まけるな!! あくのぐんだん！
The "Evil Corps," led by Don, are on a mission to conquer the universe. They set out to invade Earth first, but they struggle as some quirky Earthlings stand in their way. Eventually Don's plan to invade Earth becomes distorted...?!
The monstrous, but directionless, Don has decided to do something with his life, and he's starting by invading the Earth! But when he and his henchmen are faced with a planet full of unruly humans, is domination really in the cards?
The realization of just how many people there are on Earth has knocked the wind is knocked out of the Evil Corps's sails. Somehow, they manage to get the entire population on board their ship, but it creates a problem when Don wants to eat sushi...
The Evil Corps has been forced to start their invasion again from scratch. Desperate to try pancakes, Don wants to live in Tokyo. They drop by a convenience store, hoping to buy some sweets there...
Having found the sweets that Don was looking for, the Evil Corps has a second run-in with the loafer, who works there. Don decides to restart his invasion on a smaller scale... with an invasion of the sleepy convenience store, Bonyari Mart!
Haruta guides the Evil Corps to the Chick Street Shopping District. They could finally begin their invasion... if not for a giant chick that stands in their way! They also meet a mysterious old man, who seems to speak the chick's language...
The Evil Corps returns to their ship to plot a strategy, but finds that it has burned down. Don and Chiku are despondent, but Pepu seems to have different feelings on the matter...
The Evil Corps has lost their home. They decide to ask Don's disciple, Haruta, if he would let them stay at his house, but they are refused. But Haruta can give them a lead in finding a new base...
The Evil Corps decides to get a job, to earn the rent money for their new base (i.e. apartment). They try to get a job at a sushi restaurant, so that they can eat free sushi, but will the intimidating head chef prove an insurmountable wall to their dream?
The Evil Corps has been fired from their job at the sushi restaurant. As each blames the others for their firing, Chiku finally decides he can't take the way Pepu and Don are acting, and he runs away.
Having split up, the members of the Evil Corps decide to each get a job as individuals. The loafer gives Chiku a job handing out flyers, Chiku's fear of strangers makes it a difficult battle...
Chiku and Pepu pool the money they made at their jobs and manage to rent an apartment for the team. They're excited to finally have a new base on Earth, but...
The Evil Corps has begun life in their new apartment. Then, one day, Chiku and Pepu find a box outside. Inside, it's a letter of challenge!
