A Demon Lord and a Summoned Girl's Open World

I was a shut-in who was the ultimate player in a game, and was summoned to an isekai!
An RPG where you are a demon lord and use that power to go on adventures and make harems!

[Story]
A shut-in gamer is summoned to an isekai as a demon lord, and lives life in a harem.

A free play RPG where you can go on quests or make harems!

- Harem every day! Fun time with members every night
- When characters enter ultra-lewd mode, stimulate their weak points
to send them into crazy ero-mode.
- Lesbian play capabilities!
- Ecchi orders for members! Force them to expose themselves in public!
- Non-member ecchi targets!


What a free play RPG is:
An open world game without specific goals! You can:
- pursue harem life! Focus on non-stop sex!
- hunt animals and live peacefully, and avoid destroying the world?
- revive the demon lord power for fun?
- invade the elves and place them under your rule?
- defeat new intruders and force them to join your harem?
