Masaru Oshita possesses brown hair with visible balding and a distinct birthmark or mole. He commands the Koryukai gang, seizing control amid Tokyo's earthquake-induced power vacuum to orchestrate criminal operations, including the abduction of Kiyomi Suga. As the central antagonist, he directly opposes protagonists working to dismantle his gang and secure Kiyomi's rescue. His existence as the reincarnation of the ancient foe Lord Johakyu pits him against the reincarnated 108 stars of destiny, culminating in a fated clash with Takateru Suga, the reborn leader of these celestial warriors.
