Haruyoshi Kuga's power as the strongest exorcist is all for naught when he is betrayed by his closest ally. With his dying breath, he casts the secret Spell of Reincarnation—when he next opens his eyes, he finds himself in a different world altogether, reincarnated as Seika Lamprogue, the son of a family of magic scholars! He quickly learns that the magic in this new world is quite unlike the sorcery he learned in his past life and that he can't use it. Fortunately for him, with his mastery of curses and the hordes of youkai at his disposal, he doesn't need to. Haruyoshi (now Seika) is determined not to repeat his past mistakes in his second life by smartly laying low and avoiding flaunting his power. Yet accomplishing his goals and without drawing attention to himself proves to be easier said than done—will his powers be enough to live a happy life?! (Source: J-Novel Club)

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?
