Get Skills Through Sex! ~Ugly Old Hero's Demon King Subjugation RPG~

A lecherous hero embarks on a quest to defeat the Demon King, growing stronger by defeating female warriors in battle. Each victory triggers an intimate encounter, after which the hero acquires the opponent's combat skills—including powerful attacks, healing magic, support abilities, and more. As the hero collects skills from twelve different heroines (including a strict military officer, a sarcastic maid, ninja, and twin bunny-suited sisters), they become increasingly formidable. The player combines collected skills strategically to overcome tougher enemies and ultimately face the Demon King in a final showdown. The game features accessible difficulty with increasing complexity in the mid-to-late game, allowing players to progress steadily while gathering abilities and enjoying encounters with each heroine.
