Ophelia The Spirit Saint. One of the oldest elves, she guards the World Tree. She participated in two Wars of Sapient Beings as a primary mediator and provided a viable methodology for aligning the world's mana veins after the wars. The protector of the Shield State Spirit Clan, she is the being most likely to attain the status of a Demon God. However, day after day, she feels her soul gradually growing quiet.

Unfortunately, after being gravely injured, she fell into a spatial rift, crossed over to this world, and was saved by Ophelia.

Two sisters started living in my house for one simple reason: it was close to their school.
But each of them had their own hidden agenda.

"Big bro, please always keep at least 100 meters between you and Mikaru-nee!"
"Michiru, you’re the one who should stay away from Yuuhi-nii-san!"

Ah… my daily life is already a complete mess.
And just like that, my chaotic, nostalgic, and lively days with them began.

Your lazy sister is spending her money on new things.
Where is she even getting this money from?

You play as the Demon of Lust, disguised as a charming preacher who infiltrates a remote monastery with one simple mission: corrupt the holiest place in the region from the inside.
What starts as an easy task quickly turns into a game of psychology, manipulation, and control — because the nuns are far from innocent.

Each sister has her own personality, secrets, boundaries, and forbidden fantasies. By carefully managing daily schedules, making the right choices, and interacting with visitors, you guide them on a journey from strict devotion to forbidden self-discovery.
