Cute High Earth Defense Club HAPPY KISS!

Shuzenji Kyotarou, Kirishima Ryoma, Wakura Nanao, Manza Taiko, and Dogo Ichiroku, who claim to be the "Earth Defense Club" and do not fight anything, but enjoy a lazy daily life. One day, the five meet Karurus, who claims to be the first prince of the Honyaraland Honyara royal family, while soaking in Kurotamayu. Karurus, who came to rule the earth happily, appointed the Knights of Karurus Happy Kiss to help the defense team. Suddenly fighting a mysterious monster who rampages at school ...!?

In front of the Earth Defense Department, which brilliantly calmed the monster as the Karurus Knights Happy Kiss, Furanui, the villain who created the monster, appeared. In fact, he is Karurus' half-brother, competing with Karurus to show his qualities as the next king. And behind Furanui are three student organization officers who became the Knights of Furanui Edelstein. They turned the students in the complex into monsters in order to rule the world by spreading fear.

Nanao Wakura, the director of the Defense Department, and Daiki Unazuki, an officer of the Student Organization Inside School, continued to interact with each other with the same loose attitude as before, despite being in a hostile relationship as a magic knight. One day, a member of the Student Organization turns a high school student who works hard at an ice cream shop into a monster, but because of that, the shop does not turn around and Nanao and Taiki are temporarily pushed by the troubled shopkeeper. To work as a clerk. That caused an unexpected big response ...!?

An unfamiliar high school student with eyebrows rushes into the conversation between Taishi and Ichiroku, who have a fierce tongue-and-groove battle in Kurotamayu, "whether or not there is a reserve." His father sought romance too much to find the buried treasure, and his family collapsed. He insisted, "There is no buried treasure!" Meanwhile, the recording of the buried treasure excavation program started in a certain mountain in the city of Eyebrows. Each of the five members of the Defense Department volunteers to participate in the location because of their unpleasant thoughts.

A long line suddenly occurred at Brow Difficult High School. It was a line of students seeking a cookie that was reputed to have been made with a special recipe by Student Organization Inside School Skeletal Martha. A student who came to be attracted to such cookies. Furanui immediately felt the smell of misery from this student ... On the other hand, Martha escapes as soon as she sees Dogo Ichiroku. What kind of drama was there in their past?

Kyotarou does not bring an umbrella at all even if he enters the rainy season. Ryoma puts in Kyotarou with an umbrella, but Ata of the student organization who sees such a situation gently clasps his fist. The Defense Department enjoys a relaxing time after school at Kurotamayu, and a suspicious shadow that shows the situation from behind. The Defense Department is impatient with "Molester⁉", but the suspicious shadow is that he was a student at Eyebrow High School who wanted to get along with anyone because he saw the Defense Department that seemed to be free.

The traditional event "Swimming Tournament Full of Men at Eyebrow High School" (there is also a men's contest ☆) will be held. Some students, like Ichiroku and Martha, prepared their swimsuits with a lot of energy, while others were depressed about participating in the tournament and were not good at swimming. The tournament has finally started while various thoughts are mixed! However, unexpected things happened one after another ...

The story is summer vacation. The members of the Defense Department were spending their days as usual while soaking in the black ball bath. Kyotarou quibble with Karurus' wish to have a correct summer vacation in Japan! Karurus, who thought he wasn't happy, asked Kyotarou, "If you ask me ...". Upon hearing that, Kyotarou changed his attitude completely! For Karurus's "correct summer vacation in Japan", he took the rest of the members and struggled to make memories of the summer vacation ...

The Defense Department decided to participate in the school festival in order to maintain its appearance as a club activity. I couldn't come up with a good idea, and as a result of the members searching the club room for hints, I found "Party Dice"! Shuzenji says that this item, in which participants deepen their friendship with each other, is perfect as a product. The members were once convinced, but on the day of the school festival, the old birds screamed. The members stretch their bodies to demonstrate the game to attract customers, but ...

As usual, the five members of the Defense Department relax in Kurotamayu. The topic is that Kyotarou's words and actions are old-fashioned. The next day, I go to Brow Difficult High School as usual, but I'm surprised that Ichiroku, who is short of breath in the middle of the stairs, says "You're an old man!" I was an old man. "I was cursed because I treated Kyotarou-senpai as an old man yesterday ...?", But when I looked around, the school playground was full of students who became grandpas! ??

Ata explodes her anger with a casual word from Kyotarou. The full-scale confrontation between Edelstein and Happy Kiss is about to begin! In the midst of a fierce battle, Ata's mouth finally talks about a long-standing grudge. It's a bitter memory of my childhood ...

Happy kiss that came to Honyara Land. What they saw was a horrific coup scene. Karurus and Furanui are upset by the appearance of King Camopapa captured by the rebels. The final battle of Happy Kiss, which encourages these two people and confronts the rebel army, finally begins! !!
