The heroine's ability is to get a buff by calling people Dad.
As a result, a bunch of villains and superheroes are forced to have a daughter, and are also forced to become someone's “senile,” “has no hobbies except cosplay,” “frail and too sick to hold a knife” old dad.
Villains: What the hell, an old dad?! Wait, I told you I'm not senile! I'm not going into a retirement home! Aaaaaah!
The rich guys, satisfied: It's getting cold. Let's build another hundred retirement homes (prisons).
The heroine is the strongest support. Pairing undecided.
This is a comedy with an unconventional style and a heroine so awesome she blows the universe away. If that's your thing, come on in.
