Rangiku's Tears, the Sorrowful Parting of Brother and Sister

Matsumoto tries to get to Shōta as Yui tries to get him absorbed. Yui regains some control just as the psuedo-Arrancar who has been hiding in the shadows for all this time, makes an appearance, ambushing them with more clones and absorbing Yui. Will Matsumoto be able to hold off the Arrancar and protect Shōta long enough for Hitsugaya and the others to arrive and put an end to this monster?
