Fukayama, the final battle!

Ryohei (Yusho Nakajima) comes with his grandmother and a lawyer to consult on a request for a retrial in a case in which his father Takahiro (Takashi Kobayashi) is alleged to have set a fire and murdered his mother. When Miyama (Matsumoto Jun) and Maiko (Kimura Fumino) go to see him, they find that Takahiro admitted his guilt because he could not bear the guilt of making Ryohei the son of a criminal. Fukayama checks the security camera and notes the amount of kerosene Takahiro purchased.
