Ultimate Exorcist Kiyoshi Vol. 1 — Manga Raw / Buy Official

Kiyoshi’s first mission involves clearing a haunted school, but he spends most of the time trying to run away. When the demon Baalzebub mocks him, Kiyoshi’s sheer panic triggers a massive, subconscious strike that shreds reality and dismembers the monster. It is revealed that Kiyoshi suffers from an 'over-defensive constitution,' where his extreme anxiety acts as a conduit for destructive exorcism magic. His partner, Mina, is both terrified and exasperated by his incompetence in social situations versus his god-like combat prowess. As a high-ranking demon officer learns of this 'cowardly legend' and attacks the school, Kiyoshi faces his true test. For the sake of his classmates, the boy who is terrified of everyone finally finds the courage to stand his ground, unleashing a concentrated, tear-filled strike that shatters his enemy’s core completely.
