While chowing down at a ramen stand, Milfeulle (who is carrying Lost Technology that resembles pepper in a shaker) accidentally turns her fellow Angels invisible with it. Even worse, the Angels now have a new mission--to locate money stolen by crooks hiding out at a supposedly haunted house. Can they stop the crooks? Will the Angels become visible again?

During a mission, Milfeulle takes a detour to help an old man deliver a tsuchinoko kigurumi for a festival. Mint, displaced from her seat by the traveler, finds the box in the cargo bay containing the costume and helps herself. When she finds she can't get it off and is left alone on the destination planet by Milfeulle, she is mistaken for a real life tsuchinoko by the locals.

Ranpha and Milfeulle travel to a planet to investigate a lost technology, but decide to take part in a Takeshi's Castle type show instead. Ranpha does well, yet her successes are dogged by a long lost robot acquaintance.

Commander Huey, no relation to Commander Volcott, has a reunion with his old command: the Fairy Unit. As the now elderly women bicker and fuss, Huey reminisces about a dangerous mission they had once embarked on and how much he misses the now absent Spiphy. As the elderly women become too tired, Spiphy arrives, apologizing for being late to the party. Commander Huey chooses to leave the other elderly women behind and go out with Spiphy.

A gang of bandits resembling the Angels are robbing the corrupt Dream Foundation's vaults of cash. Two of the military's top brass come to investigate. They are soon transfixed by Commander Huey's brilliant maneuvering in bringing the culprits to justice.

One morning, the members of the Angel Brigade began switching bodies with each other (and Col. Volcott). Mint theorizes that it has something to do with the Lost Technology they were able to obtain from a previous mission. Now, they have another mission to do--stop a biker gang from causing trouble in a downtown area. The mission is a success thanks to Forte (in Milfeulle's body), but the next morning, one of the gang members break out of prison searching for Milfeulle. As the lost technology keeps switching the bodies around, the gang members becomes involved as well. Later, a team destroys the lost technology when studies showed that the device was meant to send souls to heaven. Everyone finds halos above their head.

The Angel Brigade is returning home from a successful mission where they were able to stop the activation of the "Ultimate Planet-Destroying Bio-Weapon." Still, none of them can understand how they managed to stop it. Who in the Angel Brigade gave the fatal blow? What will be the consequences for their actions?

The Angels go to a resort planet for vacation, and it seems they can get a prize of one million GCs for catching a monstrous fish. Forte wants the prize money, while Milfeulle plans to cook the fish for a meuniere dinner. However, Mint does not believe it is possible to catch the fish and wants Forte to call it off, but Forte refuses. Things go awry when the giant fish knocks over their rented boat, damaging the radio (so now they can't call for help) and the fishing mechanism, trapping Forte in it. The other Angels decide to inflate a raft and abandon her on the boat just when the fish is returning for another attack. Forte stops the fish, but the fish drags the boat and Forte and damages another rented boat.

It's Milfeulle's day off, and she plans to go hiking in the Transbaal area so she can see the flowering fields of the summit meadow. This also happens to be the one day when her misfortune takes over from her usual good luck. The more Milfeulle is plagued by misfortune, the more a galactic cataclysm is bound to happen. To prevent such occurrences, the Angel Brigade must prevent any stressful influences until Milfeulle goes to sleep again. As Milfeulle began her day off, she encounters many problems such as a ripped dress, a late bus, and an urbanized summit meadow. Forte and the others quickly fix up all the problems. In the end, Milfeulle goes to sleep happy about her day off.
