A fat guy is reborn in the world of Hokage and gets adopted by Tsunade by acting shameless and adorable.
It doesn't matter that being reborn didn't make me a rich second-generation heir, and it doesn't matter that I wasn't born with a Kekkei Genkai, because this fatty has a System.
The Fat Exchange System: as long as you have fat, you can get anything you want.
A tree without bark is doomed to die.
A person without shame is invincible.
I'm not the protagonist, but I want the protagonist's treatment.
I'll take the spotlight, and I'll be the one who picks up the girls.
I'm a happy fat guy, and I'm here to speak for myself!
