Kenzou is an elderly inmate at Green Dolphin Street Prison, and the former guru of a sect. He is sent to assassinate Jolyne Cujoh in the maximum security ward. He eventually battles Foo Fighters instead when it comes to save Jolyne. Kenzou is a Stand User, and wields Dragon's Dream.
Kenzou is a small yet athletic old man, with a heavily wrinkled and clean-shaved face, but he has unusually long eyebrows over slanted eyes. He has several thin braids on the back of the head.
Kenzou wears a furred bodysuit open on the chest, a jeweled skullcap on which are several big pearls, and a similarly jeweled necklace.
Kenzou believes that the secret to good health is "urine therapy" (drinking his own urine) every morning. His prison card also states that he has knowledge of Kung-Fu, Tai Chi, and tea ceremonies.

Dragon's Dream manipulates the concept of Feng-Shui to show the luckiest angles, and is used by Kenzou to strike from odd angles for maximum lethality. It is remarkable in being neutral in a fight and equally usable by Kenzou's foes.
In his youth, Kenzou was the leader of a very popular cult that included Hollywood stars and other famous people, reaching 30,000 members. However, his sect was soon investigated by the police and FBI. Subsequently, Kenzou and thirty four members of his cult attempted a mass suicide. Kenzou drugged everyone and put fire to the building, burning everyone. However, Kenzou collapsed in a surprisingly safe spot where the collapse of the walls shielded him from the flames and the smoke and barely survived. He subsequently received a total 280 year-sentence in Green Dolphin Street Prison for this crime, and endeavored to climb back up to the upper echelons of society where he could relive his former glory.
About forty years after his admittance at Green Dolphin Street, Kenzou's assassination talents are called for.
Kenzou is sent to the maximum security ward alongside D an G, Viviano Westwood and Guccio to assassinate Jolyne Cujoh. After Westwood loses control and frees all the inmates, Kenzou makes short work of most of the inmates and drowns them. He confronts a battered Jolyne but detects Foo Fighters and attacks it first by kicking the corpse is is hiding it. F.F. comes out and shoots Kenzou, but the corpse's leg twitches, protecting the old man.
Kenzou and Foo Fighters properly engage each other. He summons Dragon's Dream and reads the lucky spot. Thanks to that, he avoids F.F.'s shots and drives his fist inside of its throat, using a specific technique to trigger a secretion of mucus from the adrenal gland that is supposed to make his targets drown by themselves. He then turns to face Jolyne but F.F. surprisingly pierces its own throat and shoots again. Kenzou barely manages to be avoid the attack and kicks F.F. but it simply squeezes between the bars of a handrail to escape. Seeing inside of F.F., Kenzou is intrigued by the unique flow in its body but remains confident as it retains the same weak points as a human.
He reads the lucky spot again and summons Dragon's Dream, who is seen by F.F. and irritatingly explains to F.F. the ins and outs of its ability for the sake of a fair fight. After an exchange of blows, Kenzou reaches Dragon's Dream and his arm connects with F.F.'s unlucky spot. Although F.F. blocks the fist by dislocating its elbow, a series of events causes pieces of glass to pierce F.F.'s face. It opens its mouth in shock, allowing Kenzou to attack although F.F. backs off to avoid the attack. Dragon's Dream points to another unlucky spot above F.F.'s left ear. Kenzou rushes towards F.F., who attempts a kick but Kenzou then grabs the leg. When F.F. attempts a knifehand strike, Kenzou makes a straight spearhand strike at F.F.'s throat and jams his other hand in F.F.'s throat. In retaliation, F.F. bites Kenzou's fingers. In pain, the old man strikes F.F.'s liver and pushes it towards Dragon's Dream. F.F.'s arm enters the dragon and punches a corpse, which causes another unlucky series of events that make a piece of machinery slice through F.F.'s head. F.F. is now dangerously low on water.
F.F. shoots Kenzou, who is barely out of his safe spot and manages to hurt him. However, the attack is not enough. F.F. thus plans to trick Kenzou into misreading Dragon's Dream with a mirror made of water but desperately needs it to sustain itself. Kenzou begins to rant about the hell his life has been since his arrest and orders Dragon's Dream to show him the way to make his final attack. F.F. runs towards the fire extinguishing hose the guards used, pursued by Kenzou. F.F. searches for the faucet, only for Dragon's Dream to appear and warn F.F. not to touch it as Kenzou attacks. F.F. decides to intentionally put its arms in Dragon's Dream while Kenzou performs a sweeping kick on its head.
F.F. manages to sneak into the hose and break the faucet open, but its earlier prevents it from touching the water since its arms attack it. F.F. is thrown down to the execution room and the hose activates the execution sequence on the electric chair there. By pure unluck, F.F. finds itself unable to get away from the chair. Kenzou arrives and F.F. narrowly misses him with its shot again, but this time, F.F.'s shots break Kenzou's jewelry and it steps on two pearls that make it trip and fall back onto the electric chair. Desperate, F.F. attempts to kick Kenzou but the old man blocks the attack and kicks F.F. in place as the electric chair starts up.
F.F. is being electrocuted but Dragon's Dream reveals that it was able to collect the sweat from Kenzou after his effort. Kenzou realizes he's in an unsafe spot and is grabbed by F.F., who share the electrocution with the old man. Kenzou barely survives it and Jolyne approaches to finish him off despite her own injuries. However, Kenzou manages to avoid the attack and himself stands up to kill Jolyne. He tries to jam his foot in Jolyne's throat but Narciso Anasui intervenes. With Diver Down, Anasui turns Kenzou's legs into springs, preventing him from reaching his lucky spots again. Unable to stop bouncing around, Kenzou lands in a bucket and is defeated for good.
