Soul Reapers of the 10th Division—led by its captain Tōshirō Hitsugaya and vice-captain List of Soul Reapers in Bleach#Rangiku Matsumoto—are sent to escort the "King's Seal". The rare artifact is stolen during transport by the deviated Soul Reaper Sōjirō Kusaka and two girls known as Ying and Yang. Hitsugaya seems to recognize the Soul Reaper, who wounds him and leaves, and abandons his post to pursue the man and leaves his squad behind to fend for themselves. Later, the Soul Society suspects Hitsugaya of treason, orders his immediate capture, and puts his whole squad under house arrest.
