“Did you know? They say that being accomplices is the closest kind of relationship in the world.” This is what Toriko said to Sorawo not long after they met on the Otherside. A little over a year has passed since then. Now that the threat of Satsuki Uruma is behind them, there's something else Sorawo must face; a genuine confession of love from Toriko, with only one week to respond. Through a series of conversations with herself and those around her, Sorawo begins to reinterpret her relationship with Toriko... Sorawo and Toriko's bizarre tale of exploration and survival is coming to a climax!

Romance is boring, so Sorawo has created a special kind of relationship with Toriko that is all their own, but she struggles to communicate what exactly it is to the people they know. Meanwhile, Sorawo and Toriko’s exploration and study of the Otherside continues. During their summer break, the pair take a job from DS Research to help a private military company do some anti-Otherside training at the Farm. And it sounds like Runa Urumi will be involved too…?
