Saikyou Onmyouji no Isekai Tenseiki: Geboku no Youkai-domo ni Kurabete Monster ga Yowasugirun da ga

Betrayed by his allies and on the verge of death, the strongest exorcist, Haruyoshi Kuga, desired only one thing—to be happy in his next life. Using the secret art of reincarnation, he was transported to another world. Reborn as Seika Lamprogue, third son of a distinguished family of magic scholars, he's found to have no magical power whatsoever, which is an unacceptable shame in a family of mages. However, he soon comes to realize that his new world's magic is nothing compared to the sorcery he mastered as an exorcist. With his control over divination, curses, and legions of youkai who serve him, his life in this new world should be a breeze! The only question is: how can he make use of those powers while laying low to avoid another untimely demise?
