Gizou was originally born from the Shiranui Household, before becoming a part of the Yuzuriha family.
Jet Black Bride Arc
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 Arc
Bouquet Toss To The Future Arc
