Kuni Shizuko was the first born of Kuni Girakuma. In 644 Girakuma's family was struck by a sickness that was unidentifiable to any Kuni. Only her father was strong enough to survive the ravaging scourge, but he watched his wife and children die. Determined to find a way to undo their demise, Girakuma set out to find an escape from death. In the 9th century Girakuma was a maho-tsukai who had mastered the Art of Oni Naming. He took the hands from his dead daughter and sacrificed them (along with his own blood) during the summoning ritual. Girakuma's servant wa an Oni he called Shizuko (quiet little helper). [1]
