Rize Blue's protagonist, Shou Aoyama, launches a solo mission to rescue Aikawa Momoko, the Rize Pink heroine, who has been captured by the evil organization Sador. However, he is ambushed by the demon monster Garuga, who attacks him. Shou transforms into Rize Blue and battles Garuga, but just as victory seems within reach, Sador appears and attempts to steal Momoko's soul as a hostage. Shou resists, but is tortured by both Garuga and Sador, ultimately suffering defeat. Sador crucifies the captured Shou, tortures him with electric shocks, and erases his consciousness as a warrior. Furthermore, driven by his lust for men, Sador extracts Shou's soul and replaces it with Momoko's, creating a Rize Blue whose body is Shou's but whose mind is Momoko's, which he then proceeds to manipulate and abuse. Sador torments this hybrid form relentlessly, until finally, both mouth and ass completely violated by Sador's soldiers, the broken hero is forced into humiliating masturbation amidst their cruel laughter, meeting a tragic end.
