Ijuuin is funny: as if a spider would constantly sit on his head.
The blond guy's name in the Japanese raws is Masaki not Misaki if I saw it well.
but that's what they've been calling him.. MASAKI
In the first two chapters I definitely read Misaki.
You are right. I didn't even notice because I knew his name was Masaki. In the first manga his name is Masaki too
The translator did mention in Myreadingmanga (I think) that she made a mistake by writing 'Misaki' instead of 'Masaki' as she translated it through Korean raws. And apparently, the Korean raws got it wrong first and she kind of blindly follows. Hahah so excuse, the first 2 chapters of this volume.
