VN Ren'Py [Koikatsu] Mika's Adventure NTR HAREM [v0.1.5] [Piruluk]

vexingzion · May 15, 2026

Overview:
Play as Mika — an adorable priest with a cute face, a demon's cunning, and a shameless appetite for conquest. Chosen by the powerful demoness Lilith, Mika is tasked with infiltrating the Hero's party, corrupting his companions, and stealing every woman who catches his eye. Mika happily accepts. After all, someone's got to do it — and who better than a cheerful, shameless pervert with a talent for trouble?

This is a **light-hearted, humorous, and unapologetically perverted Netori + Harem** Visual Novel. The story is a parody-style adventure where Mika's personal mission — conquering women of all races — runs parallel to the Hero's quest to save the world. Every city, kingdom, and race brings new women, new stories, and new opportunities for Mika to find his next conquest.

Content Warning:

Mika's journey begins when Lilith gives him his mission. Together with the unsuspecting Hero's party, he will travel across a vast world — visiting bustling human cities, savage orc territories, ancient elven forests, underground dark elf cities, and the legendary dragon peaks. While the Hero fights to save the world, Mika fights to conquer its women.

An upcoming update will add a large world map with free exploration. Every location is filled with memorable NPCs — a blacksmith who secretly loves cute dresses, a guard who desperately wants to be remembered, an S-rank beastwoman mercenary who fights dragons by day and shares her bed with Mika by night. Future updates will introduce women of all races — elves, demons, dragons, mermaids, and more. Every corner of the world hides someone worth meeting, and worth conquering.

This isn't just about stealing girlfriends. It's about traveling the world with a shameless, cheerful pervert — chosen by a demoness, welcomed by a hero, and trusted by no one who values their wife or daughter.
