Premise
Powerful exorcist Haruyoshi Kugano is betrayed and fatally wounded by his student. Using a reincarnation spell to be reborn, Haruyoshi vows to become unbeatable in his new life. However, his spell goes awry; rather than being reborn in Japan, his soul ends up in another world similar to European Medieval Era. Reborn as Seika Lamprogue, he sees the world uses magic that functions differently that his jutsu; though this doesn't stop him from his plans. He now just wants a peaceful life, but his curiosity and iota of compassion lead him into trouble repeated.

Characters

 * Seika Lamprogue (セイカ・ランプローグ)
 * A powerful exorcist reborn into a world of magic. As his spirit is not native to it, he lacks any magical power. Instead, he uses talismans and jutsu to manipulate the six elements—Water, Fire, Earth, Air, Light, and Shadow—and spells/curses leaving everyone confused because they have no concept of his mystical techniques.

 * According to Zor's status vision, Seika is the labeled "Most Terrible Demon King"; heavily implying Haruyoshi's soul took the vessel meant for the Demon King to reincarnate. Leaving possibility both Seika and the true Demon King were reborn in the wrong bodies.
