After going to rescue Aoi, Hanako-kun and Nene are thrown from No. 6's boundary and suddenly find themselves in a strange village, where they meet a girl named Sumire who seems to have a history with No. 6. Witnessing Sumire's "wedding day" up close might just give Nene a hint on how to resolve the school's impending crisis and save Aoi-but she'll have to survive it first! Meanwhile, on the very banks of the Far Shore, Aoi and Akane finally put into words exactly what they mean to each other...
