Episode 40. Ren, Kanzaki, Asakura and Toujou are fighting off a horde of Zelles that interrupted their brawl. From the side, Kitaoka notices all of them and decides to unleash his Final Vent to take them all out. He lampshades the fact that it's been a while since he's done his incredibly cool finisher... before a Zelle knocks him over the bridge and beside a very confused Ren.
Kitaoka: *Slots in Final Vent* It's been a while since I've done my incredibly cool finisher- GAH!
Ren: *Sees Kitaoka crash onto the streets, stares at him while a horde of zelles is attacking him* Kitaoka?
Kitaoka: ... Yo.
