Eris of the Scorching Flames: Beautiful Bumbling Hero Eris

Story

I'm the hero, Eris Violet of the Blazing Flame! Wielding a flame-wrapped sword that slices the attacking demon clans in two is a beautiful girl clad in crimson armor. Slender yet fresh and dignified, this beautiful girl was the nation's one and only strongest beautiful-girl hero... Onto the lovely face of that beautiful-girl hero, splat, clings a grotesque monster. Captured after a blunder, Eris, still chained in the demon clan's research lab, was continually violated in her mind, monsters attached to her as mental contamination... As if mocking Eris desperately enduring, it seemed it would go on forever... but not noticing the opening left by the demon clan, who let their guard down thinking she was as good as a burnt-out husk, Eris desperately counterattacked and somehow escaped that hell... yet what had been carved into her body was... a transformation into perpetually throbbing, sensitive flesh... Eris desperately tried to keep her broken state hidden, but her body's condition affected even her work as a hero, and reluctantly, in order to apply for extended leave... she honestly reports the reason to her superior Kiryu, and in exchange for approving this beautiful-girl hero's application, what he proposes is... that the one and only strongest hero... be reduced to a fellatio pig...
