I Am a Hunter of Hundreds of Ghosts in Heianjing

In his previous life, a gamer who was trapped in a hospital bed due to a back injury traveled back in time to Hayabusa Kazama, a civilian orphan on the outskirts of Kyoto during the Heian Era, and awakened the ability of the "Hundred Demons Illustrated Book". In this world where demons are rampant, he has no spiritual talent. With his absolute insight into "weaknesses", training and wisdom to the limits of mortals, he hunts demons and ghosts with pure physical means, embarking on a path of violent aesthetics in which a mortal body is comparable to demons.
