Cutie Kenko is the primary antagonist featured in the live-action special episode Pretty Guardian Sailor Moon: Act Zero. This character is a human male who operates as a jewel thief, and his criminal activities drive the central conflict of the story. His background is largely defined by his chosen profession; for a period of six months, he and his three female accomplices committed a series of successful robberies targeting jewelry stores throughout the Azabu-Juban district. Beyond his life of crime, his hideout is filled with equipment and props, indicating that his crew also functions as stage magicians when not conducting heists.

In terms of physical appearance, Cutie Kenko is a young man with black hair that features light grey-dyed sections covering his forehead. He has dark, obsidian-shaded eyes. His attire consists of a long-sleeved tuxedo combined with leather elements that extend to the lower part of his legs. He is never seen without a very long red rose, which he typically holds, and a small knife is attached to the left side of his belt. His personality is not extensively detailed, but his actions portray him as cunning, theatrical, and ruthless. He commands his minions with authority and shows a cold determination to achieve his goals, even resorting to extreme measures such as attempting to cut a swallowed key out of a teenage girl’s body.

Motivation for Cutie Kenko is straightforward: he is a thief driven by the acquisition of valuable jewels. His role in the story is that of a villain whose crime spree inadvertently brings together the main characters. He plans to rob the jewelry store owned by the mother of Naru Osaka. During this final heist, his minions easily overpower a group of girls dressed as homemade Sailor guardians, including Usagi Tsukino disguised as Sailor Rabbit. When Cutie Kenko attempts to open the case containing the most valuable gems, Usagi snatches the key and swallows it, forcing him to retreat with her as a hostage to his hideout.

His key relationships are primarily with his three unnamed female minions, whom he directs to attack and capture his enemies. His primary adversary is Sailor V, the crime-fighting alter ego of Minako Aino. After Sailor V tracks him to his hideout using a device planted on the jewel case, Cutie Kenko engages her in battle. He proves to be a notable threat, using his abilities to damage her before the police, alerted by the other girls, arrive to arrest him and his entire crew. The character does not undergo any significant development, as he appears solely as the obstacle to be overcome in this single episode. His defeat and arrest conclude his part in the narrative.

Regarding notable abilities, Cutie Kenko and his minions employ combat techniques and weaponry inspired by stage magic. His signature prop is his long red rose, which he can throw to create a flashbang-like effect that stuns his opponents. He also wields a sword sharp enough to cut through solid objects and carries a concealed dagger. He uses a radio to play disorienting sound effects, such as a helicopter, to bluff that reinforcements are arriving. His minions attack using coordinated formations and sticky strings, and they place hostages inside boxes used for magic tricks. The character’s recurring use of roses as a theme visually resembles the fighting style associated with Tuxedo Mask in other versions of the Sailor Moon series.
