Yuiitsu is sent by Academy City to Baggage City with very sensitive, top-secret documents and to negotiate with the now decimated Anti-Academy City Science Guardians. She speaks with an old man who sets the Guardians' policies and forces his hand by demonstrating that it would be best to end the conflict now, while negotiating she uses that argument that if Academy City were to weaken and no longer be the capital of the Science side, the Kihara Family would spread throughout the world, a fact that terrorizes the old man. He agrees to sign the papers Yuiitsu brought with her, which ends Baggage City's involvement in the conflict against Academy City.

Yuiitsu goes to a secret underground laboratory beneath District 3, where Kakine Teitoku is sealed in a giant room. There, she explains to Kakine the situation with Fraulein Kreutune and asks for his help with the situation. She understood that Kakine would likely cause chaos and destruction, but since she is a Kihara, it doesn't matter to her. Thus, Yuiitsu lets him loose in Academy City.
