対魔忍アサギ外伝～カオス・アリーナ編～

Asagi, who had been captured by Oboro, underwent a humiliating remodeling of her body, magnifying her sexual feelings thousands of times greater than that of a normal human being. Asagi's body trifled with, she is unable to control it by force of will alone. Thus, in the end for Asagi, Oboro has arranged her to participate as a combatant in the Chaos Arena, an organization of illegal martial arts.

When she loses, a disgraceful lynching awaits her, but how long can Asagi continue to fight, day in and day out, in the ring...!?
