Trauma Quantum  

Trauma Ryoushi Kesshou, トラウマ量子結晶〈クオンタム〉

Tokitou Haruto, during his first year in middle school, lost all of his friends because he became obsessed with a science fiction novel. He started calling men "Kei" and women "Florlain," which spread throughout the school at that time. Unable to cope with the sudden exclusion, Haruto continued to isolate himself throughout his middle school years. Now, as a first-year high schooler, he faces a new challenge: one day at school, the classroom becomes perfectly still and time stops again. Having experienced this time-stop multiple times, Haruto begins to wonder if it's actually a dream. However, all doubts stop when he meets Sakazaki Kuon, who is also part of a team that defends the world from monsters that attack using the time-stop dimension: Kohakjal. Could it be possible that Haruto is the only one who can truly fight off these monsters?
