Inside the Box

After meeting Rando and Eru from the everlasting summer island of Yura, Ryuhei and his friends learn that the island is not unrelated to the Shibuya incident. Ryuhei and Rando's strong feelings for their hometown cause them to clash over something, and when Desaria appears, he and Eru are isolated in an elevator. During their brief respite from the battle, Ryuhei is shocked to hear the name "Kazuhazuka" in the old island legend of the "dead man's return" told by Eru.
