I feel like sis is about to die
The commenters below are acting like they didn't read the prologue and read hints towards the goals of the adults around her in this current world.
At this point in time she really just sees them all as the same type of people.
Hope she gets to become more open or at ease with studying.
So she will summon a very handsome spirit with a rotten character? A consensus of "hot guy" and "evil spirit". The summoned spirit will immediately make passes on all her friends etc.
...I feel like the teacher has zero experience with kids if he wasn't worried about her immediately going out and trying it after that sudden show of interest.
i... i'm honestly getting so angry over how she's acting. Sure, spirits and stuff are really cool but didn't she hear the part about the guy summoning a sinister spirit and that he ended up passing away within a year?
