The Sealed Genryūsai

Head Captain Genryusai Yamamoto of the Thirteen Court Guard Squads steps in to battle Aizen. Genryusai’s attempt to incinerate Aizen in a blazing inferno is thwarted by Wonderweiss, whose Ressureccion form extinguishes the flames. Wonderweiss is revealed to be a Mod Arrancar created by Aizen for the sole purpose of sealing away Genryusai’s zanpakuto, Ryujinjakka.
