The story telling is so bad so many skip and jump from school arc to war arc. Who all these new peoples that keep appearing ? Most of them are awful. What the MC want ? Why he should care with those awful side peoples ?
This story is just confusing.
Motherfucker just slashed his sword so hard he ripped a hole in the fabric of space and voided the monster THEN goes to have a kaijuu battle with its brother!! O.O
I feel like this should've had an extra page, where the guy who made all the oni attack is looking at this like "What the fuck is this shit? What. The. Fuck."
