The Rebellion Begins: Rise of Muramasa

Prologue
In a cave in Soul Society, the Zanpakutō spirits are seen sitting at a table. Haineko gets restless, wondering when they will be able to leave, and tells the others she is going outside. She is stopped by Sode no Shirayuki, who tells her that they are still missing several people. Haineko wonders how many people are going to join them, to which Kazeshini cackles, stating that he can handle this on his own. .
