The Swooping Descent of the Dark Emissary! The Propagation of Malice

While tracking the arrancar, Rangiku and Shota discover that its song can force souls to walk towards it, and that it can multiply itself without limit. A researcher from the twelfth division reveals that another arrancar is creating the copies, explaining their inability to die. The Soul Reapers defeat all of the arrancar, and Shota finds the person he was searching for: his sister, Yui. More clones from the arrancar attack, and Yui runs to the park, where Shota admits that he abandoned her out of fear.
