IN A CITY FULL OF PEOPLE, YET FEELING COMPLETELY ALONE...
Tucked away in Ikebukuro is a little shop of curios called Sonohara-dou.
While there are many intriguing items to be had at this store, one
person in particular visits for Saika, the cursed sword in Anri's
possession. Although the visitor leaves empty-handed, Sonohara-dou is
broken into in the middle of the night. Was anything stolen? Anri isn't
sure, but Yahiro, Kuon, and Himeka swear to help her out. Meanwhile,
busy again as a courier with a mysterious new job, Celty hears about
Anri's problem. She visits the shop out of concern, only to see
Akabayashi and a host of other Saika-related people... What is the
mystery that lurks behind this sudden rush for control of Saika?!
