Okay for anyone who don't know who the three new Japanese people in this chapter are
Miharu = Haruto/Rio's childhood friend
Aki = Haruto' sister
Masato = Haruto's step brother (Haruto's mom remarried Masato's Dad after the divorce)

The only factor all the isekai'd people are they were in Haruto's presence when they got transmirated so they prolly just got dragged by his transmigration. Liselotte and the fox girl was with him when the bus got into an accident.
The other Japanese people got summoned there...
Well it was kinda shitty way for the father to ignore his son all his life. I honestly like that he's seeking his own goals in life instead doing something because it's expected of him. I just wish he won't fully side with Demons and become edgy and shit but that's prolly where the story will go.
