Trauma Ryoushi Kesshou

A middle school student named Tokitou Haruto lost all his friends after reading a science fiction novel and using terms from it in school. The experience left him isolated for years. As a high school freshman, he encounters a recurring phenomenon where time stops. He begins to question whether these episodes are real or dreams. His uncertainty ends when he meets Sakazaki Kuon, who also experiences the time stops. She is part of a group that fights monsters emerging from the time-stop dimension called Kohakjal. Haruto is now faced with the possibility that he may be uniquely connected to this group and their mission.
