Gao's Buddy Skill Is On!.In Sengoku Academy's reference room, Sophia offers the Dark Core to Kiri. At first hesitant, Kiri recalls the time when Rouga first brought him to Sengoku while also remembering Rouga's philosophy of winning. Kiri is almost tempted to accept the Dark Core when he hears Gao's voice calling for him. Sophia knocks Kiri unconscious when Gao and Drum arrive. Sophia unleashes Disaster Force and teleports Gao and Drum into the sky, sending them plummeting. It is at this time that Drum activates his Buddy Skill, which gives both himself and Gao the ability of flight and save themselves. Gao and Drum then return to the fight field to face Shosetsu, who received the Dark Core from Sophia.
