About
Taking place right after Aizen's defection from the Soul Society, a festival is being held. Ichigo and the others attend before going home. However, some special Mod Souls have been accidentally uncovered by a member of the Department of Research and Development; one of the Mod Souls, Kai, takes the form of the researcher and takes his fellow Mod souls away. Some of the Mod Souls begin festering with hatred and transform into copies of Hollows, such as Shrieker and Grand Fisher, causing havoc throughout the seireitei.
