The Drifting Classroom, Vol. 1

Not sure if this is the right fit?

Consider Blood on the Tracks, Vol. 1 by Shuzo Oshimi.

“Blood on the Tracks, Vol. 1 reads like a slow, tightening claustrophobia: ordinary days drip into escalating menace as art and pacing spotlight small domestic details until they feel threatening. Its useful part is the way quiet suburban scenes become disturbingly intimate, pulling readers into the protagonist’s uneasy perspective. Main limitation is the relentless discomfort — scenes meant to unsettle may feel repetitive or gratuitous to some, and those seeking lighter horror or clear explanations will find the first volume deliberately opaque.”
