On the day of the battle, Chiyu asks Haru and Takumu to join them on the field so she can see the battle to the end. As the sudden death duel begins between Haru, Takumu and Seiji, Haru is ambushed by an ally of Seiji’s, Black Vice, who possesses a deceleration ability. As Haru remains trapped, Takumu takes on Seiji using his new incarnate ability, Cyan Blade, managing to overcome Seiji’s Demonic Commandeer ability and slice off one of his arms. Seiji explains that he was bullied by his older brother, driving him to become more powerful and get his revenge. He then proceeds to take Chiyu hostage and torture her, causing Takumu to lose his will to fight. As Haru laments the hopelessness of the situation, he manages to regain his resolve and break free from Vice’s grip. As Seiji prepares to finish off Takumu, he is stopped by the arrival of Kuroyukihime, who managed to enter the field from Okinawa using the item she got from Sulfur Pot. Engaging battle with Vice, Kuroyukihime encourages Haru to stand up and defeat Seiji.
