With the defeat of Muramasa, peace has returned to the Soul Society. Renji, Rukia, and the other Soul Reapers are having a good time at the Kuchiki mansion's party, when the place is suddenly attacked by two unknown beings. Having left her Zanpakuto behind, Rukia falls into danger when, to her surprise, the manifested Sodenoshirayuki comes to her rescue.
Uryu begins his own investigation to track down the enemy who attacked him. As he goes around searching for clues, he notices that people close to Ichigo are acting strangely. Meanwhile, Ichigo's Fullbring training is nearing its completion.
Ichigo escapes from his house in confusion after witnessing his friends and family welcoming Tsukishima as if they've known him for years. Regrouping with Ginjo, Ichigo learns that the same change has also happened to Riruka and the other Xcution members.
