Elna is a well-endowed nun who lives in Ulunka Village.
One day, her nun-ly duties take her far from home, to the village of Adus.

There, she's tasked with watching over the demon Renis, a monster sealed in a nearby cave. Deep within the cavern, Sister Elna discovers a book...
And releases the creature!


Sister Elna's sacred power keeps her safe as the demon enters her body, but she can't keep it under control for long.

In order to preserve her virtue and that of the village, she has to take a special aphrodisiac every day to quell the monster's urges. If she does this and still stays pure for 7 days, the possession will end.

Will the men around town be eager to help? Or will they give in to their beastly urges?

So begins Sister Elna's week-long trial...Nuns Elna and Ira goo about their duties while combating the erotic influence of the demon that lives deep in Elna's body!

Will they triumph or give in to lust? it's all up to you!

- A homeless man tries to get closer to Elna
- The local alchemist cooks up some special drugs
- A mischievous youngster messed with the village girls
- A young bartender won't cut Elna off
- The village chief requests "help"

These situations and more as the hapless holy women fight to seal the evil spirit!

*This is not a fully-voiced work.

"There are loads of different endings (virgin, NPC-based, bad ends, etc), a gallery room, and even an all-unblock switch!
Heart marks appear on story goals a locations for H scenes, making everything easy to find!"The main focus is on the H scenes.
Every day, you'll be given the choice to take the aphrodisiac or not.
Take it, and Sister Elna's lust increases -- but she'll be safe from the demon.
Don't take it, and the demon will take over, leaving Elna in a deeply sexual state for days.There are also horny status effects
that kick in after H scenes, plus
commentary from Elna!
Elna's lust can go up, as well as her depravity.
As lust increases, so does the cap on her depravity. If it goes too high, Elna won't be so pure anymore...Yoou can also take conttrol of Sister Ira
and relive events that happened when Elna wasn't around.
Outside of some H scenes, Ira doesn't join in the sex. Unless she gets a little too horny...Also includes loads of costumes, like the ever-popular cow swimsuit!
The outfits and H scenes are intertwined, so one enhances the other!Even the pose art isn't safe from the sexy shenanigans!
Staff and NPCs can get harrassed, too!There is also a toggle for pubic hair, which will affect the art.
Feel free to change it any time to give the game a different feeling!
