Heian period. In the dead of night, within an old Japanese house, a young man in a loose brown robe sits before a pale, weak child, his eyes lifeless and his smile stiff. He addresses the child as "Lord Ubuyashiki." The child, with long hair and a sickly pallor, glares at the young man with a demonic, crimson-like gleam in his eyes. Despite the young man's calm demeanor, his trembling hands betray his fear. This Heian period... is not what he expected.
