I don't know much about the game but isn't it decided by what word you pick during the Sorting Hat? Like ambition is Slytherin, Curiosity is Hufflepuff etc.Mio in the weirdo house makes sense. Trelawney was from there, too. Both fortune tellers.
Lui went into Gryffindor. I guess she's still a bit of a chuuni.
Your wife is retarded, so Hufflepuff makes sense.
Everyone else would rather filthy gaijin not dirten the roads of glorious nippon except maybe as roadkill. Quite commendable. Letting foreigners steal your schtick just causes Vshojo.
"Curiosity" definitely fits Nene more than any of the other words. She certainly feels like a Hufflepuff.
