Inuyasha: The Vow Beneath the Kikyo Blossoms

Lin Yan, a modern archaeology graduate student, transmigrates after touching an excavated clay fragment from a Kikyo shrine maiden ritual at a museum. He isn't the strongest fighter, but he has the ability to "empathically relive the past": by touching an object or the ground, he can sense and briefly reexperience fragments of emotional memories left behind there. He hasn't come to replace Inuyasha, but to serve as an "understander" and fill the void in Kikyo's soul, the lack of a feeling of being accepted.
