According to the series' origins in the 2001 Elf H-game, Kisaku Itou, the sadistic protagonist of Kisaku The Animation, is a master of blackmail whose methodical depravity distinguishes him from his impulsive brother Shusaku. His slow-burn approach—gathering compromising material to coerce women like Aoi and Madoka—creates a tension that’s as psychological as it is sexual, hooking the viewer with anticipation.  The explicit scenes, packed with ahegao faces, X-ray cumshots, and taboo acts like forced anal and public gangbangs, are designed to overwhelm, the censored visuals teasing just enough to spark imagination.  Kisaku’s twisted charisma, blending menace with perverse honor (he scorns consensual sex as “weak”), makes him a villain you hate to love, his control over his harem igniting primal arousal through dominance and taboo.
The fanfiction above amplifies this by plunging readers into Kisaku’s world, where every thrust and moan mirrors his calculated chaos.  Aoi’s reluctant submission and Madoka’s eager corruption play into the series’ themes of power and betrayal, while the orgy’s escalation mirrors Kisaku’s insatiable greed, keeping readers horny with vivid, relentless debauchery.  Kisaku is a raw, unapologetic ride that leaves you wanting more because of the combination of schoolgirl innocence and milf aggression that is tied to Kisaku's blackmail-driven lust. Every scene is dripping with forbidden heat because of this.
