Uji to Mononoke no Monogatari

Tales of Exorcist Clans and Specters. Reborn's new assignment was to train the next heir to the Vongola-Uji, a world-renowned exorcist clan. He expected to handle a no-good, weak boy who is ignorant of his heritage but what he met instead was a fluffy brown-haired teen who knew more than what he should know and his mysterious set of friends. A Secret Santa gift for SkyGem.
