As the Hopper Dopant escapes Kamen Rider Accel after he transforms into Accel Trial, Yamashiro reveals that Ryubee offered him money for his research before learning the truth about him. After answering Philip that he does not know his family, Ryu takes Yamashiro in into custody so he can tell the police all he knows about the Museum. At the Sonozaki mansion, Ryubee is visited by Jun Kazu, the white-suited representative for Foundation X, assuring the man that with Wakana leading the Museum, the group's funding would be worth it.
