Incubus Isekai is an adult Ren'Py game created by ReioO000, presented with 2D animated visuals. You play a reincarnated character in a conventional fantasy isekai setting, where you fight monsters, gain levels, and meet beautiful women. The overall play structure blends sandbox-style freedom with turn-based combat, letting you progress through encounters and character growth.
The current build is v0.11, released July 28, 2026, and development remains ongoing. It runs on Windows, Linux, and Android in English, uncensored. The latest update adds a magic attack system with mana usage, new mana potions and a magic staff, unified potion handling, and merged SlimeAttack and GolemAttack into one attack system with magical options. It also customizes the Android icon and loading screen for all players.

Fixed some visual bugs.
I also refactored the entire prologue, combat system, and shop so that in the future each stat can have a unique purpose instead of only scaling weapon damage(for example, agility could allow you to dodge or attack more times, and so on) however, this is not implemented yet, just like the mana system
v0.09

New Character ( Claire )
2 new scenes for Claire
New minigame in the dojo (if you think it looks similar to minigames from other games… that’s just your imagination)
Minor & UI Changes:
Added temporary notifications for the cheats menu
Added a button to unlock the gallery
Andd some bugs fixes:
the orbs from previous matches don’t get cleared
Claire appears in the background when announcing the ending
check text opacity at the end of the minigame
add a pause or menu after finishing a match because you end it full force
when you get stronger it kind of freezes, I think it's because the bar gets disproportionate

because claire had negative time
the time stops at -0.1
you win has no opacity
challenge: claire looks ugly
each time I save a game after doing a minigame, loading it takes you to the last minigame you did

If you unlock the gallery, don’t skip the scenes, it gets stuck
