If あなた was making a team which characters would あなた put on it?
Here is the idea, あなた need a team of fighters to save world from a big treat and あなた can recruit any animé character あなた want.
Only one character from each animé.
5-7 Members with atleast 2-3 females.
Don't choose too many of the same type.
And at last don't just choose the most powerful characters instead try to come up with the best team with a good balance.
リスペクト to best and most detailed idea.
