MC reincarnated in an Eroge JRPG he played as the protagonist's sidekick that uses scarf as a weapon~ It's a modern fantasy setting~ Got adopted(?) by the Principal(powerful hot mom if I remember) of the school he's going to attend~ He interacts with the Heroines before the Protagonist~ The only Heroines' characteristics I remember are: Principal's Bookworm Daughter A Princess Female Knight(Obviously since there's a princess) Japanese Beauty(the usual) which the MC loves since the game I think there are more but I forgot or haven't read it yet~ I really want to read it again~
