The Tsunayashiro Clan’s Future and Tokinada Tsunayashiro

Neither He-El nor Shunsui Kyoraku had expected this. There was actually someone inside the Great Spirit Library. This ancient, solemn, mysterious Great Spirit Library, which recorded a series of major events and secrets of the Soul Society from ancient times to the present, had always been controlled by the Tsunayashiro Clan. It was protected by layer upon layer of defenses, and no one could force their way in. Even obtaining authorization from the Central 46 Chambers was difficult. One also needed the Tsunayashiro Clan's permission.
