As Carmen awakes in Matsumoto, Nagano, Shadow-san has once more vanished. At Matsumoto Castle, she learns Shadow-san's Katana is part of a Daishō, realizing he stole the other half of the pair. Meeting with him, Shadow-san aims to return the katana, having stolen it as initiation as a thief. Carmen encounters Paper Star, who distracts her so Lady Dokuso, a veteran V.I.L.E. agent, can retrieve the Tantō; reporting her success, she is offered to replace Shadow-san should she prevail. Carmen meets Shadow-san, learning his true name 'Suhara' from the curator, who is his elder brother- Hideo. Shadow-san explains that, while Hideo was content with his scholar's livelihood, Suhara was not content living poor and became a thief. To prove himself, he stole the katana while Hideo saved the Tantō, and has regretted the choice ever since. Now understanding, Ivy covertly disarms the guards before Shadow-san fights, while Carmen fights Paper Star for the Tantō and entraps her. As Dokuso poisons Shadow-san, Carmen arrives and forces Dokuso to flee. They return the Daishō to Matsumoto Castle, and Suhara pleads with Hideo, who still does not forgive him. Shadow-san then joins Carmen's crew, no longer calling Japan home
