Teruyu (played by Shotaro Mamiya) is shocked to learn that Maruko (played by Kenta Suga), who lost in the evil bear game, lost his life for the bet, but he warns her that possessing the “Devil Key” is dangerous.He declares to Ryukin (Jun Hashimoto) that he will challenge the game and collect keys to get close to the person (Ozawa Yukitsu) who killed his father Seiji (Yoshikawa Koji).

Teruyu doesn't want to put his precious friends Hatsu (Tatsuki Tanaka) and Yuki (Furukawa Kotone) into more danger, and tries to distance them by telling them not to get involved again, but Hatsuyu feels for TeruyuAnnoyed.Finally say the harsh words.

At the same time, mixed martial artist Takeshi Hyoto (played by Eijin) won a martial arts competition with a landslide victory.I was alone in the waiting room, staring at the “Demon Key” in my hand.Although it is difficult for Hyoudou to win, since he encountered the Demon Key, he has won consecutive battles and gained money and power.

At the cabaret club where he went to celebrate after the Hyōdo match, Chiya Uesugi (played by Ryusei Ryo) appeared in front of him and suggested that he could get what he wanted if he took Oda Teruyu's key.

After the quarrel, Yuuki wanted to reconcile Huiyu and Hajime, and invited Huiyu to dig out the video letters buried when the three were in their second grade of middle school, but Huiyu flatly refused.He asks Hajime to invite Teruyu, but Hajime is busy raising funds for the company and is in no mood to do so.

Yuki, who had no choice but to go to junior high school alone, found Teruyu standing in front of the school gate and forcibly pulled him in.When the two dug out a corner of the campus, they found a tin box and took out a DVD from it.

Huiyou was about to read a video letter in the classroom. He turned to the direction where the sound came from and saw Hyoudou pointing a knife at Yuki.Hyoudou, who had the devil's key hanging on his chest, put pressure on Terutomo and said: “Give me your key!” Hatsu arrives and pounces on Hyoudou to save Yuki, but he is taken hostage.

Hajime tells Terumomo and Yuki to escape.Huiyou, who didn't want to lose the one he cared about anymore, inserted his “Devil Key” into the floor and shouted “Come out, Devil!” Gadot emerges from the tornado and the second round of the Akuma game begins!!
