Makeruna!! Aku no Gundan!

Young Don resolves to form his own ragtag army to conquer the cosmos after seeing an advertisement about how anyone can command an invasion force. The aloof Pepu and the gaming-obsessed Chiku assist him, though it is still debatable how valuable their membership is. The crew's novice captain sets his sights on Earth as their first objective with his two henchmen by his side. The guidelines state that Earth should be a straightforward target, but the situation quickly gets out of hand. As it turns out, persuading almost seven billion people to merely submit and accept their new master is no simple task. After being completely destroyed by humanity, Don and his squadron crash-land on Earth and start looking for a way to enslave people. However, due to their unexpected failure, they now have to deal with more urgent problems, such as paying their rent and getting food, so their aspirations for planetary dominance will have to be postponed for a little while.
