Scarlet Flash Battle Princess Remilia

A dark fantasy game where you play as a male protagonist hunting a legendary female swordsmaster known as the strongest warrior. After trapping her in combat, you can corrupt and enslave her, progressively breaking her will and pride through repeated battles and sexual dominance. The game features turn-based dungeon combat where victory allows you to inflict various corruptions on the heroine, along with a daily-life segment where you witness the psychological aftermath of her degradation. Multiple corruption paths exist—from weakening her physically to implanting masochistic traits and breaking her spirit entirely—letting you customize how thoroughly you reshape her into your obedient pet.
