Odc. 6: Soubi walczy z bezbolesną parą Zero, osłabiony nieobecnością Ritsuki.

6

Ritsuka's teacher once again tries to go to Ritsuka's house to have a parent-teacher conference, but she runs into the next fighting pair from Septimal Moon: Natsuo (the Fighter) and Youji (the Sacrifice), who call themselves "Zero." She tells them her full name and the boys use it to take control of her. Soubi walks by and saves her, but gets in a fight with Natsuo and Youjo even though his power is at a quarter of what it usually is because Ritsuka is not with him. Soubi is having a hard time in the fight, and has one arm shackled, and thinks back to a lesson at the Fighter school when he learns that Zero is an artificial pair that can't feel pain.
