Tensei Onmyouji Kamo Itsuki: Nidoto Jigoku wa Gomen nanode, Enma Daiou no Shinki de Musou Shimasu @COMIC

Kamo Kazuki was mistakenly sent to Hell. Burning in hellfire for eons, his soul became tainted, and he was forced to undergo a purification ritual in a world overrun with monsters. He became an onmyoji to speed up the purification of his soul, but because of the immense divine energy he received from King Enma, only eccentric characters gathered around him! He ended up being liked by the Yamahime, the descendant of the Great Tengu, and even the monsters he was supposed to defeat. "King Enma, don't give me unnecessary events...!" Accompanied by a group of eccentric companions, Kazuki's journey to defeat monsters, with his fate at stake, now begins. He returns from Hell! The unrivaled Yorozuya of the young onmyoji is now open for business! (Source: Comic Corona, translated)
