Plot
As his bead bracelet is removed from his wrist, Kyo evolves into a monstrous creature right in front of Tohru, causing him to evade her. Tohru follows after him, but she unknowing trips behind a tree and begins to vomit. Akito appears, as he taunts her about the knowledge of the Sohma family secret. Akito soon leaves when Shigure locates the two. He apologizes for her finding out the truth about Kyo, but regardless she continues to search for Kyo. Kagura talks with Yuki, saying that only Tohru can help Kyo, which, in turn, convinces Yuki to find Tohru, due to his affection for her. It is revealed that Kazuma took Kyo in as his adoptive son, because his grandfather suffered the same cursed during his time.
