I mean the Pheasant one is straight up gonna be NTR (chubby wife with front bang)
So the party members:
Monkey - react to tomboy
Pheasant - chubby wife with front bang
Dog - spiral glass imouto
Momotaro - shy, plain-looking milf (with glasses, because ofc)
I'll take the genius inventor little sister with spiral glasses. We can get rich off of her inventions and she's probably a beauty underneath those glasses.
...wait. What's that sound?
Oh shit, I just pissed of the glasses oni. I've gotta go.
Each Oni bragging about the woman in his life. Wouldn't be shocked if the followup is them fighting each other over who's the cutest while Momotaro sneaks off.
