Crossover: Master of Slaying Scum

Tu Yuming, a laid-back onmyoji who only wants to coast through life, is tricked into another world by his ancestor, Abe no Seimei, when he's fifteen. Seimei claims it's to make him the best possible heir. This world is crawling with ghosts... though, in Seimei's words, they're teaching aids. Facing the arrogant teaching aids who think highly of themselves, the young Yuming lets out a soft sigh. A look of compassion settles over his exquisite features. With practiced ease, he forms a hand seal and summons outside help in the form of shikigami: For example, a gravity user from a certain port Mafia, the ruler of all demons in Kanto, and the tenth-generation head of an Italian seafood company who prefers not to reveal his name...

The teaching aids: ??? You call that onmyodo? Theme: Saving the world and saving yourself
