Jet Black Bride ArcEdit
Gizou is waiting for Medaka Kurokami on the aircraft carrier Black, along with the other suitors. He introduces himself as pervert number zero, and states that if there is no bread, panties will also work. He wonders whether breakfast will be bread or panties. Gizou listens on as Bukiko Udou explains the rules of the second Jet Black Wedding Feast, and smiles when Kairai asks what order they should go in. Gizou is the last to battle Najimi Ajimu, making another pun concerning panties before he does so. However, he is easily defeated by one hundred of Ajimu's boss skills. As Gizou lies defeated, it is revealed that he and the others are actually nothing more than doubles for the real suitors.
Unknown Shiranui ArcEdit
Bouquet Toss To The Future ArcEdit
Gizou confronts Medaka at Hakoniwa Academy as part of the 100 Flowers Run, along with Iihiko and the rest of the Shiranui family. After Medaka defeats Kairai, Gizou pulls down her skirt; Medaka sends him flying with a kick in End God Mode. His message to Medaka is that she can change ideals and panties.
- The names of the six doubles all contain kanji that hinted at them being impostors. His name, 偽造 (Gizou), can mean "Forgery".
- Gizou's preference for girls' panties is fulfilled by Yuzuriha, who does not mind exposing her panties while fighting.
