House of the Restorer (Official Colored)

Seongwoo Yoo, age 17, possesses the ability to see the “original form” of an object by looking at its old memories. With both his parents absent, Seongwoo works part-time while living alone in a giant mansion his grandfather left him.

One day, a girl by the name of Ran appears, claiming she’s the guard captain of Jungpyeong-gun, the grandson of Baekje’s 21st king... Not long after that, unwelcome, unhuman guests start pouring in.
