Kagure Blue, Mekage Suzu of the Holy Ninja Task Force Kagelenger, chooses to fight alone—an action strictly forbidden—to defeat the evil female ninja Jelarna. This battle is also driven by her grief over the death of her friend and fellow holy ninja, Kaede. However, a new crisis emerges when Mercenary Ninja Centipedecurse, who wields poisonous curses, allies with Jelarna to destroy Suzu. Centipedecurse's cursed centipede parasite embeds itself in Suzu's heart, forcing her to fight through excruciating pain. The torment takes a severe mental toll, eroding her willpower until she loses control and succumbs, falling into depravity by orally servicing her enemies. Ultimately, her story ends in a devastating BAD END that irrevocably alters her fate.
