A mysterious man informs a group of strange beings that it is the time to strike. Ichigo Kurosaki wakes up in Zangetsu's dimension and receives a warning of what is about to happen. Meanwhile in Seireitei, the captains and lieutenants of Gotei 13 begin to feel their zanpakutō's detachment from them, but do not understand what it means. At night, a group of ryoka attempts to enter Shigekuni Yamamoto-Genryūsai's abode. Yamamoto and Sasakibe confront the intruders but what they see leaves them in shock. Later, the captains and lieutenants are ordered by Yamamoto to gather at Soukyoku Hill. Upon arriving there, they are met by the mysterious man, who calls himself Muramasa. Sajin Komamura attacks the intruder with Tenken but instead of hitting Muramasa, Tenken attacks Komamura. Reappearing as a human form, Tenken strikes down Komamura. The rest of the Soul Reapers prepare to attack but find themselves unable to release their zanpakutōs. Their zanpakutōs take on human form and stand beside Muramasa, who tells the Soul Reapers that their zanpakutōs have renounced them and declares war.
