Denjiro is a samurai from Wano Country and one of the Nine Red Scabbards who served as Kozuki Oden's retainers. After becoming grief-stricken over Oden's execution 20 years ago, Denjiro's appearance changed and he started going under the name Kyoshiro. With this new identity, he became a yakuza boss and recruited followers to form the Kyoshiro Family. Eventually, he started working for Oden's usurper, shogun Kurozumi Orochi, as his money changer and bodyguard; he would successfully keep his true allegiance to the Kozuki Family a secret and bide his time until the day would come of the Scabbards reuniting for the final battle to take down Orochi and Kaido. Apart from his Kyoshiro identity, Denjiro would disguise himself at night to rob the rich Flower Capital citizens and give to the poor living outside, earning him the moniker "Ushimitsu Kozo". He also took care of Oden's daughter Kozuki Hiyori for the past 13 years, raising her to become the oiran Komurasaki. Denjiro is a slim yet very tall and muscular man standing at 306 cm. Before Oden's execution, he used to have rather big and round eyes as well as dark hair that was always kept in a long ponytail. He was always seen wearing a pair of sunglasses. When he was young, he wore a dark kimono with a four-leaf clover pattern; his face was also much rounder compared to its more pointed edges as an adult. As an adult, he wore a dark kimono with a small crescent moon on the left side of the chest.
Because of his grudge towards Orochi, Denjiro's appearance changed sometime in the last 20 years. His eyes became slanted, he no longer wears sunglasses, he grew large sideburns, and his hair color changed to light blue. Eventually, he also started hiding his ponytail in a massive faux-pompadour. He wears a dark blue kimono with circles and target patterns on it, as well as a blue, high-collared cape. During the raid on Onigashima, he took off his faux-pompadour when revealing his identity. When preparing to infiltrate the castle, he wore the Beasts Pirates foot soldier uniform. When going out as Ushimitsu Kozo, Denjiro puts a hokkamuri bandana over his head to hide his hair. When he was young, he took pride in his abilities to manipulate people and get what he wants. He was a fan of Kozuki Oden even before becoming his retainer, and held him in high regard for his bold actions. Oden's death was so traumatic that the very process of grieving caused Denjiro's facial structure to be altered. Denjiro's loyalty and strength of will cannot be understated. An unspecified time after Oden's execution, Denjiro (as Kyoshiro) became a subordinate to Kurozumi Orochi and spent the better part of the past 20 years earning his trust in order to find a chance to overthrow him and restore the Kozuki Family to power. Denjiro has shown great emotional control, despite his immense hatred for Orochi. He is able to perfectly restrain himself from expressing it and even bowed to the latter as well as protecting him from Zoro in order to not jeopardize the Kozuki revolution on the Fire Festival.
After becoming Oden's retainer, he and the rest of the Scabbards worked to aid him in any way, until they were caught by Shimotsuki Yasuie during their attempt to steal his money. After being lectured by Yasuie, Denjiro and the rest of the Scabbards became noble and educated samurai. Denjiro, being the more knowledgeable one, was the one who would take some of the teaching onto himself. Denjiro served as the voice of reason for Oden, especially when it came to Kuri's finances. Denjiro attempted to advise Oden against making foolish decisions like giving Orochi money and leaving Wano, though Oden was rarely persuaded. Denjiro has also shown to be very kind, as after becoming Kyoshiro, he works hard in secret to give money to the citizens left impoverished by Orochi's tyranny, and he also took the responsibility of caring for Hiyori after she was separated from Kawamatsu. As Kyoshiro, Denjiro acts as a cheerful man who loves to drink. While intoxicated, he was unafraid of speaking bluntly about the shogun Orochi despite the potential danger, and he mocked the shogun for believing a prophecy from Kozuki Toki about his downfall. In this state, he is prone to experiencing rapid mood swings, ranging from laughter to intensity to falling asleep. He falls asleep in public frequently due to being up in the middle of the night as Ushimitsu Kozo. Due to his self-indulgence, Denjiro does not appear to bother with his obligations as the boss of his family. This was seen when he ordered his subordinate to contact Queen himself for an assassin to eliminate an individual who refused to comply with their extortion. However, he still cares about his family and will do what he needs to have them defended or avenged, regardless of how low-ranking they are. Ultimately, he is quite diligent when he feels like it, as he was able to raise Komurasaki to become Wano's top-ranking oiran. He even protected Orochi as the loyal guard dog from Roronoa Zoro's attack against the shogun. However, his efforts to help Orochi are all a ruse to help the Kozuki Family on the day of the final battle.[2] As Denjiro trapped Sasaki, he showed a confident smile as their revolution proceed smoothly, finally elated that his patience in waiting for a chance to avenge Oden has paid off as he can finally exact revenge on Kaido and Orochi.
