It is either Eirin's drug, Nitori's invention or Marisa's mushroom fault!!
Yep it was all of them.
Its name is "let's skip all steps together"!I wonder why they had this in reserve at the shrine.I released an amazing invention.This is a mushroom used to produce love-inducing medicines.Aah, this.
It's a medicine capable of getting people to like each other, it's amazingly strong and quick.If eaten raw the mushroom has a stronger effect.I remember Marisa showing one of these to me.
