Just when Tsuna is adjusting to his new life, his school's delinquent leader, Kyoya Hibari, is now targeting Tsuna. Fortunately for Tsuna, Hibari is more interested in fighting Reborn.

A strange Chinese infant, I-pin, comes to Japan in order to kill Tsuna.

Tsuna finally meets Kyoko's older brother, Ryohei, but things don't seem to go the way he wanted when Ryohei nags Tsuna to join the boxing club.

Reborn's former student comes to Japan to visit Tsuna; Dino teaches Tsuna what it means to be a Mafia leader.

Tsuna is suddenly stricken with an embarrassing disease. Unfortunately for Tsuna, the only person who can cure it is a doctor who does not like to treat men.

Lambo is given a simple task of giving Tsuna his lunch by Tsuna's mother, but when he bumps into I-pin, who was carrying a box of nitroglycerin, a mix up causes things turn for the worse.

Tsuna is faced with a dilemma when Haru and Kyoko eat a Gyoza bun that proves fatal to normal people. Even worse, there is only one antidote available.

Reborn strengthens the abilities of Gokudera and Yamamoto through specially made "training programs", which appears to be more than an exercise course. When he discovers that Reborn and Tsuna seem to be paying more attention to Yamamoto, however, Gokudera feels left out.

It's New Years and Tsuna and his 'family' has to battle the Chiavorone Family in a traditional Vongola event. Although, the losing family has to pay a price of 100,000,000 Yen.

All of Tsuna's friends show up at school during winter to help him babysit I-pin and Lambo. Although, in a turn of events, everyone besides Tsuna seems to just want to have a snowball fight, so Reborn turns it into another one of his staged competitions.

When Reborn drops Tsuna and his friends off on an isolated mountain, he and others become lost in the wilderness of the mountain.

Tsuna is recovering from his wounds from the previous episode and discovers that recovering in peace and quiet isn't possible with not only his friends visiting, but the fact that Hibari is in the same hospital.

It's Valentine's Day Kyoko and Haru are at Tsuna's house to make some chocolate, only to his horror to find that they are being helped by Bianchi. Tsuna and his friends have to find away to get Bianchi away from them before she ends up poisoning the chocolate.

A small kid named Futa bumps into Tsuna. What Tsuna is not aware of is that Futa is a Mafia informant, whose "rankings" are 100% accurate, and this makes him a widely sought-after target, forcing Tsuna and the others to protect him.

One by one, students at Namimori High are being targeted by an unknown gang. It seems that some of those targets are some of Tsuna's friends, and he has to stop the unknown gang before they attack his friends.

After a battle between Gokudera and Chikusa, one of the gang members; Tsuna, Yamamoto, Gokudera, Bianchi, and Reborn set off to capture and defeat the mysterious gang from Kokuyo, only for Yamamoto to run into trouble right off the bat.

After a quick battle between Bianchi and M.M., Haru and Kyoko have been targeted by the serial killer twins Jiji and Didi under Birds' order. Threatening to kill off the girls, Birds plays with Tsuna and his friends, commanding them to beat Tsuna up.

With Tsuna running after Futa, the others are left to deal with the one claiming to be Mukuro himself. He proves to be too much for them in the state they are in, so all hope lies with Tsuna coming back in time. However, even if he does, there is only one Dying Will Bullet left.

With the reveal that their foe wasn't the real Mukuro, everyone breaks into the Kokuyo Middle School building to face the true mastermind. With no Dying Will, Gokudera having to fend off both Chikusa and Ken, and everyone else unconscious, all hope looks lost, but one of Mukuro's captives my prove to be the ace in the hole.

Even after his apparent death, Mukuro still isn't finished as he possesses the bodies of everyone his hit with his trident. There seems to be no way for Tsuna to win with everyone under Mukuro's control and no Dying Will, when Reborn's pet Leon gives off a strange glow.

With the new Rebuke Bullet, Tsuna has reached a new level of power, but it still may not be possible to defeat Mukuro, who still has not revealed his strongest form.

After the defeat of Mukuro, life goes on normally and Tsuna and his friends all move up a grade at school. However, none of them are in the same class, so Reborn offers them a challenge to catch him, with the prize being a change of the roster. Later, they celebrate at a sushi restaurant owned by Yamamoto's father only to find they do not have enough money to pay for their food and have to work off their debt.

When Lambo uses the Ten-Year Bazooka, however, something malfunctions and creates a teen Lambo with young Lambo's mind, and to make matters worse, this Lambo escapes from the house.

Reborn invites Tsuna and his mom to a vacation resort, but they first have to ride on a cruise ship to get there. Once on the ship, Tsuna spots some of his friends, who all boarded without tickets, and he now has to keep them from being caught, but first, he has to catch them.

At Mafia Island, Tsuna fails to prove his identity as the Vongola Family's 10th boss, and is transported to the back of the island where he is given a new chance to prove himself. There, he meets another Arcobaleno, Colonello. Colonello and Reborn put Tsuna through tough training. Meanwhile, another Arcobaleno invades the island with an army.

Tsuna has to swim 15m in school, but being unable to swim, he is trained by Yamamoto, Gokudera and Haru in the public pool. Everyone has his own method, and they decide to compete to see who can get Tsuna to swim the furthest. Reborn interferes this time with a Vongola dolphin that has a dangerous complexion.

To pay off the damage caused in the previous episode, Tsuna works as a lifeguard with Ryohei, only for them and the other boys to be challenged to a swimming race by older lifeguards. Later, Tsuna and his friends run a stand during a summer festival to continue to pay off their debt, only to have run ins with Hibari, and a group of thieves.

On a day out having fun, Tsuna and his friends come across a boy using the Dying Will Flame and is being attacked by a swordsman, but when they try to help, they prove to be no match for him.

Dino manages to fend off the swordsman, Squalo, and explains the situation: a subgroup of the Vongola Family called The Varia is after the Vongola Rings which are held by the leading members of the family, which he then proceeds to give to Tsuna and six other people. They have ten days to train in order to become strong enough to fight off The Varia. Meanwhile, Tsuna's father returns.

Tsuna and the other six members chosen to hold one of the 7 half rings, all start to train, in preparation to face The Varia. Some even get them selves their own home tutors. Meanwhile Tsuna is told that besides him the First Vongola also used gloves, and he will soon find out who the two others with the ring are.

All of them are going through training by their respective tutors.Tsuna is being train by reborn,Yamamoto by his father,Gokudera by Dr Shamal,Ryohei by Colonello and Hibari by Dino.

Under Reborn's instruction, Tsuna embarks on a search to find the missing Lambo. At the same time, Haru is testing Tsuna to find out whether he is still the kind and compassionate Tsuna who had saved her in the river.

A Vongola weapon alteration expert shows up to improve everyone's weapon. Meanwhile, two men appear, aiming to assassinate Tsuna.

All of the selected one are force to battle against each other who have the same type of rings

Lussuria and Ryohei fight in a heavily lighted boxing arena. Ryohei then remembers his sister and the reason he became a boxer. He then gets back up ready to fight.

Ryohei continues his fight with Lussuria. When the battle seems to favor Lussuria, Kyoko & Hana appear and give Ryohei the support he needs to release his Extreme Sun Maximum Canon. Later, Tsuna wonders if Lambo can really fight in the next round.

Lambo's fight versus Leviathan of Varia. As a 5 year old and a 15 year old, he stands no chance to the "Levi Volta" attack of Levi. However, when the 15 year old Lambo used the 10 year bazooka, Lambo from 20 years later appears. The 25 year old defeats Leviathan with relative ease using his "Electricco reverse" and "Electrico Cornuta" techniques, but the 5-minute limit of the 10 Year Bazooka ended, and Lambo reverted to his 5 year old form.

Tsuna's ring is taken from him for having interfered in Lambo's fight. Tsuna's father leaves for Italy, after Xansus hints at having done something to the 9th boss of Vongola. While Tsuna continues his training, Gokudera is trying to perfect his ultimate technique.

Gokudera fights a losing battle to Belphegor. Belphegor's attacks were somehow going right to him without much effort on Bel's part. However, Gokudera figures out the secret to his trick, and unveils his new tecnhique: Rocket Bombs. However, once Gokudera finally strikes Belphegor, he starts to act funny.

After Belphegor reveals his true nature, Gokudera lures Belphegor into the library for a final stand. After a brief struggle between the two, Gokudera won, but as the time limit for the match expired, it became a struggle match for the two. Not wanting to lose his friend, Tsuna persuaded Gokudera to abanadon the ring.

Gokudera's match concludes and the next battle is announced: the battle for the Ring of Rain between Yamamoto and Squalo. Hibari causes a commotion at the school as the battles have caused major damage to the grounds. Dino reveals that Squalo once defeated the Swords Emperor of the old Varia and that Yamamoto's Shigure Souen Style is useless against him. Yamamoto receives a shinai from his father that transforms into a katana only when using the Shigure Souen Style.

The battle for the Ring of Rain commences. Yamamoto shows off his new Shigure Souen Style and it looks like victory is assured. But slowly Squalo gains the upper hand as none of Yamamoto's attacks are hitting. He then reveals that he can read through all of Yamamoto's moves.

Having crushed the Shigure Souen Style before, Squalo becomes confident once more. Yamamoto manages to hurt him with the 8th Form: Pelting Rain, after Squalo revealed he had encountered a different 8th Form. Yamamoto reveals his newly created 9th Form as Squalo bares his fangs. The Shark and Rain collide on this exciting conclusion.

On Tsuna's side of the world, he is curious to know who is the Guardian of the Mist only to faint at the sight of Chikusa and Ken. At the Vongola Compound in Italy, an attempted recon mission is enacted by Iemitsu to find out what happened to Vongola the 9th. When Tsuna regains consciousness, he and his 'family' find out who is really the Guardian of the Mist.

Having found out that Chrome Dokuro is the Vongola's representative of Guardian of the Mist, Tsuna acknowledges her as a part of the family and allows her to take part in the duel. After many exerted attempts to attack 'Marmon' (now known as Viper of the indigo pacifer), Chrome eventually loses to the illusions. However, the battle does not end and an unexpected person comes in to assist in the battle.

The unexpected person, turned from Chrome, turns out to be Rokudo Mukuro. A series of chaotic illusions battle starts. During the fight, Tsuna experiences flashbacks of Mukuro on how he sacrificed himself for Ken and Chikusa to escape. Rokudo Mukuro ends up being the winner, almost killing Marmon, who escaped with his reserved power from the battle field. Rokudo Mukuro fainted after the battle, turning himself back to Chrome.

Everyone in Tsuna's family is worried about the outcome of the Cloud battle. If it's Hibari that's fighting, then they should have a one-hit K.O. no-worry win. However, when it seems that the daunting Gola Mosca is more than he appears to be, even Tsuna, who's still training to complete his Zero-Point, gets very worried.

After the Cloud ring conflict, Xanxus tries retrieve Gola Mosca. After Hibari halts his attempt at retrieval, Mosca goes on a rampage, shooting wildly at everyone friend and foe. Back at the 9th's house it is revealed that the 9th living there is in fact a fake. Tsuna comes to the rescue of his friends and holds off Mosca at which time Mosca attacks Tsuna only.

Tsuna opens Gola Mosca to find the body of the 9th who was its power supply. Xanxus is revealed to have been behind a coup attempt. It is revealed that Tsuna has met the 9th before and that he was the true choice for the position of the 10th Vongola Boss. After which the Sky Match is announced for the next night. Xanxus gives the sky ring to Tsuna before he leaves. The 9th is taken for medical attention and everyone returns home. Tsuna returns to school the next day where he receives an amulet from Kyoko.

The Battle of the Sky gets started and the strengths of Xanxus and Tsuna are exposed. Not to mention a couple of the guardians seem to be coming around.

All the Guardians have been injected with a poison and rendered unmovable. Hibari, however, manages to help himself and on the way saves Gokudera. On Xanxas' side, Bel and Levi have also been freed. Gokudera rushes to save a helpless Lambo from Levi. Meanwhile, the Sky battle has begun to heat up. Who will get all the rings first?

Tsuna prepares to use the fruit of his hard training: the Zero Point Breakthrough. Xanxas, however, recognises this attack and proceeds in a hectic beatdown. Reborn reveals that maybe using to attack won't beat Xanxas anyway. Is Tsuna going to be okay? Meanwhile, Hibari has saved Yamamoto and Gokudera freed Ryohei. Tsuna's family are all saved but Chrome is...

Xanxas is firing relentlessly leaving no time for Tsuna to execute his attack. But Tsuna is getting...stronger with each hit he takes? What is the Zero Point Breakthrough Revised? Dino arrives at the battle with an unexpected guest and Chrome is being held hostage by Marmon and Bel. What will Gokudera and Yamamoto do?

Dino's unsuspected guest is revealed to be Squalo, who Dino saved instead of Yamamoto and brings to see the sky match. Yamamoto along with Gokudera propose a trade between Mammon and Bel, which turns out to be a well played trick but is countered by Mammon's illusions which binds both Yamamoto and Gokudera, Gokudera of which drops the remaining rings. Tsuna and Xanxus have a struggle where Xanxus powers up, which seems to turn the tide of the battle. Tsuna and Xanxus then charge at each other which results in a huge explosion. After the smoke clears, Tsuna's customized version of the Zero Point Breakthrough (Tsuna adds the word custom on the end of breakthrough to make it his own version). The Zero Point Breakthrough Custom froze Xanxus's hand. Revealing the opposite of the Dying Will Flame.

As the fight continues, Xanxus tries to break the ice and release his flames. However, Tsuna prevents him and begins to freeze Xanxus' entire body. As Xanxus becomes frozen, he reveals that this scenario is similar to when the 9th Vongola froze him. Squalo finally reveals the whole story of what happened 8 years ago during the "Crib Incident" and how the Varia attacked Vongola headquarters but failed due to the freezing of Xanxus. Meanwhile, Ryohei is shown freeing Gokudera, Yamamoto and Chrome from Mammon and Bel's trap. However, Mammon was able to get all the guardian rings and is seen at the end hovering over the frozen Xanxus saying that all the rings will reawaken Xanxus.

After the fight, Xanxus is released with the power of the 7 rings which he was originally released by from the 9th. There is a short flashback of his life, and a secret is revealed: Xanxus is not actually the 9th's blood son, and so, the rings rejected him. At the end of this, an elite group of Varia arrives.

He then appears in the world ten years in the future. Hayato Gokudera also appears and soon realise they are not being sent back after the usual time limit. They are then attacked by Lal Milch who is later revealed to be an ally.

Tsuna and Gokudera venture with Lal Milch in the woods. They come across a machine dangerous called a Mosca Robot. The future Takeshi Yamamoto defeats the robot and leads them into the hideout where they find out the truth and the secrets. There, Tsuna meets Reborn.

Tsuna, Gokudera and Yamamoto goes out of the hideout and to the outside. They try to find Kyoya Hibari but run into Lambo and I-pin protecting Haru Miura and Kyoko from two Millefiore Family members from Blackspell. Just as Future Takeshi Yamamoto is about to defeat them, a cloud of purple smoke appears and the past forms of Takeshi Yamamoto, Lambo, I-pin, Haru, and Kyoko appear.

Yamamoto is knocked unconscious by the Millefiore members while trying to protect everyone. Gokudera uses his ring and opens his box weapon to reveal a cannon. He defeats one of the Millefiore members. While protecting Kyoko, Tsuna manages to defeat the second Millefiore member by using his Zero Point Break Through technique.

While recovering from his injuries, Tsuna learns the only way to return to the past is to gather the guardians, defeat Byakuran and eliminate the man with the glasses, Shoichi Irie. Lal-Mirch teaches Tsuna, Yamamto, and Gokudera about the rings and boxes; The rings are revealed to emit a flame depending on the element of the user and boxes contain weapons or animals enchanted by those flames. Lal Mirch asks Tsuna to open a box of an unknown element as the sky flame is able to open boxes of all elements.

Tsuna manages to open the box given to him by Lal Mirch to reveal an Arcobaleno Pacifier. When the base receives a SOS signal, it is found to be from Hibird. Kyoko is also revealed to have run away from the base.

Tsuna and Lal Mirch manage to find Kyoko at the house of the future Hana Kurokawa. During the fight with Gamma, Gokudera is almost killed but saved by Yamamoto. Settling their differences, they decide to work together to defeat Gamma. Yamamoto is knocked unconscious during the battle.

As Gamma is about to deliver the finishing blow to Gokudera, the future Hibari arrives to save him. Hibari manages to defeat Gamma with his hedgehog box animal and tonfas, both which are enchanted with the cloud flames.

When the battle is over, Hibari shows Tsuna and the others the entrance to his base which is also connected to the Vongola base. Once everyone returns to the Vongola secret base, Bianchi and Fuuta arrive to give new information on the Millefiore Family. They reveal the location of the Millefiore base on Japan which is under the Nanimori Station underground Shopping Mall. They decide they must train before beginning their attack on the Millefiore.

When I-Pin becomes sick, Kyoko and Haru decide that Haru should bring her to a doctor. Haru manages to sneak away from the Millefiore and visit a doctor. Haru is later noticed by one of the Millefiore members. Bianchi arrives to try and assist Haru but they both become cornered by the Millefiore member and his box weapon of bees. Tsuna later arrives and defeats the Millefiore member by using the Zero Point Breakthrough.

Lambo sneaks out of the base when Fuuta goes out to fix a loose cable. Lambo is captured by a Millefiore member who demands the location of the Vongola base. Lambo uses him to his advantage in order to get some candy. After learning of the kidnapping, Tsuna and Fuuta follow a trail of Lambo's candy and find the Millifiore member with Lambo. As Tsuna gains the upper hand in combat, the Millifiore decides to threaten Tsuna with Lambo's life. Afterwards, Hibari, annoyed by the disturbance in Nanimori, easily defeats the Millefiore member

Tsuna's training with Hibari begins. During their battle, Tsuna is trapped enclosed by Hibari's hedgehog box weapon. Hibari reveals Tsuna will die from lack of oxygen if he does not escape. Tsuna, reaching his limit, prepares one final attempt to burn through the hedgehog. He burns a small portion and realizes that small portion is where the Vongola ring was. He realizes his X-Gloves flames must be equal to the Vongola ring's flames to break through. Tsuna collapses from the lack of oxygen. Just then, Tsuna's Vongola ring emits images to Tsuna's head and reveals the past crimes of the Vongola.

Yamamoto and Gokudera begin their training. Whilst Tsuna is in the spike ball, he has a visions of all the Vongola Bosses and their past wrong doings. The bosses demand Tsuna to accept the history of the Vongola but Tsuna refuses. The first Vongola Boss, Vongola Primo, accepts Tsuna as the sucessor to the Vongola. Tsuna then escapes with the help of his upgraded X-Gloves which now emit the sky flames. Continuing their battle, Tsuna grabs one of Hibari's hedgehog box weapon and releases it on Hibari. Meanwhile, Chrome is shown to be inside an abandoned building.

Hibari decides to let Tsuna live, wanting to fight Tsuna when he is finished training. The history of boxes is explained thoroughly by Hibari. Whilst explaining, Bianchi is also explaining everything she knows to Gokudera. It is said that the boxes were made because of coincidence and sold at extremely low prices. There are more than three hundred designs. Meanwhile, Byakuran reveals the 7³ plan; the 7 Mare Family Rings, the 7 Arcobaleno's Pacifiers and the 7 Vongola Family Rings that will give them the ultimate power. Squad 8 is sent to investigate deaths in Japan.

In this episode, Tsuna and Yamamoto learn about Gokudera's past. It is revealed that Hayato is an illegitimate child, born of Bianchi's father, the head of their mafia family, and a famous pianist. It is revealed that she died in a car crash when Hayato is still young. Hayato doesn't find out that she was his mother until years after the crash, but when he finds out, he runs away from home. After learning Hayato's history Glo encounters the past Chrome.

Glo Xinia immediately attacks Chrome, who is in a state of panic and confusion due to suddenly being transported 10 years into the future. Just as the battle seems to be over, in Glo's favor, it is suddenly revealed that the Owl weapon that Glo has been using is actually possessed by Rokudo Mukuro

With no escape routes available, and Mukuro Rokudo being in a weakened state, Mukuro explains to Chrome Dukuro that it is up to her to win the fight. Drawing power from both her trust in Mukuro and the Vongola Ring, Chrome's illusions become far more effective, to where even Glo can't tell whether or not they are real. The fight soon concludes in a victory for Chrome, and the future Ryohei is introduced at the very end of the episode.

Chrome is brought back back by Ryohei to the Vongola Hideout, and delivers the message the thesurviving Vongola family members—including the Varia—along with several Alliance families, are planning to attack the Millefiore family in just five days. With the 7 Guardians finally reassembled, it is up to Tsuna to decide whether or not they will participate in the attack.

Due to the Dellinger Phenomenon, the sun has interfered with all signals and has caused technical difficulties worldwide. Because of this, the defenses within the hideout are turned off and the setting becomes dangerous. Reborn explains a little about the Negative Tre ne Sette rays and how the Arcobaleno are affected, and he fears for Lal's life because she is a defective Arcobaleno. She seems to be affected more than Reborn. Meanwhile, Lambo and I-Pin have gotten themselves stuck inside the second power supply room and become blocked in when the backup defenses are turned on. Lambo has destroyed part of the control and the room suddenly becomes dangerously overheated. Finally, it takes Tsuna in his Dying-Will Mode to open the doors and release the children.

As Tsuna trains thoroughly for the raid in five days, Lal Milch is experiencing problems due to the Negative Seven Rays, so she excuses Tsuna to check on Yamamoto and Gokudera. It seems that Yamamoto needs more training, and Gokudera has flaked off from his training. Meanwhile, in Millefiore HQ, Byakuran has found out that Leonardo Lippi is an impostor whose real name is Guido Greco, a man who murdered 15 men and escaped from prison a year ago, similar to that of Mukuro. Byakuran finally reveals that Guido is also Mukuro, and they engage in a battle. Meanwhile, Tsuna finds out Lal's condition and starts to worry, but Lal Milch lectures him on 'choosing the right hell.'

Chrome's condition has been stabilized after Hibari tells her it is her duty to live as the Mist Guardian. She uses the Vongola Ring and creates incomplete organs, enough to keep her alive. Tsuna, after examining the situation, tells them the raid will begin in five days.

Tsuna continues his training with Hibari in preparation for their plan five days later. Hibari is sick of dealing with Tsuna and asks him how long he`s going to keep fighting like a herbivore, and leaves to his room. Tsuna cannot think of any way to use his V.R. X Gloves. The person who gives him an idea for a killer technique is Lambo, who is always annoying, and Haru. Tsuna feels that he can fight because he has support… He takes those feelings and puts them into his technique. Source: crunchyroll

Tsuna apologizes to Haru and Lambo and thanks to them, figures out that behind power, is support. Tsuna tries to release a "hard flame" with "soft flame" supporting him, but fails because he can not find the balance. While unconscious after blasting into a wall, Tsuna and Chrome are sent dreams by Rokudo Mokuro of a strange white "box".Gokudera has finally mastered the Systema C.A.I. and finding a small cat in one of the boxes.

Gokudera's kitten box weapon dashes off and Gokudera makes chase. Recaps of Goukerdera and Tsuna in the future arc starting with episode 74.

Byakuran calls Irie and tells him that Mukuro has been defeated and that he was found to be transmitting data, possibly to the Vongola Tenth. Byakuran tells Irie that he is the most important person in that base and must escape if they invade the base. Irie for some hidden reason, can't leave. Irie calls all the Milliefore Japan members in the base and tells them he shall leading the base now. The members are outraged and prepare to attack Irie until a swordsman by the name of Genkishi tells them anyone who opposes master Irie will be killed. Irie becomes the boss of the base. Afterwards the Vongola have received the data transmitted by Mukuro. In it was the picture of the white box Tsuna saw in his dreams. Training is resumed and Reborn gives Yamamoto a box about the sword emperor.

Yamamoto and Gokudera have finished their training. Meanwhile, Tsuna loses his charm made by Kyoko. Later, he bumps into her and she gives him it back, then the first black spell battle is recapped. Also, Hibari reveals that the Millefiore battle simulation reveals a 0.0024% chance of success for Vongola. Thanks to Glo Xinia, Millefiore now knows where the Vongola Base is.
