About This Game

One day, the sealed book suddenly exuded light, and a powerful succubus invaded Eruna's body. To suppress the succubus in her body, she has to keep taking “love potions”... Can Eruna resist the effect of the love potion and protect her purity from the men and the succubus?

Detailed Description

【Story】

In Urunka village, there's a busty sister— Eruna.

One day, after receiving requests for assistance from other villages, she left her hometown and went to "Adus Village."

She was given the task of guarding the "Succubus Rhaenys" who had been sealed in the village cave since ancient times.

Eruna came to the cave and found an old book in the depths.

When Eruna approached, the book suddenly released eerie shine,

and the sealed succubus was freed.

Even though she tried resisting, the succubus still entered her body, almost possessing her.

Eruna was then saved by her fellow sister, Aela. However, the succubus still remained in her body...

Then, to resist the uprising desire under the influence of the succubus, she needs to drink “a special love potion that suppresses the succubus,”

next, she has to endure the horniness, which is the side effect of the love potions, for "Seven Days."

Of course the perverted men in the village will not let the busty sister have it easy...

Eruna is about to begin her lustful seven days...
  

【Features】

Eruna, a gentle and kind sister who fulfills her duties in a rural village

and the side character, Aela, a sister in the church of Adus Village.

The two sisters have to hold back the overflowing lust because of the succubus while fulfilling their duties

and seal the succubus again. "A short RPG about sisters enduring lust and avoid erotic things.

・The homeless middle-aged man who lives in the village without permission and always tries to approach Eruna.

・The weird middle-aged man who runs a alchemy store and develops H○rny potion.

・The young bar keeper who keeps making Eruna drink despite her inability to handle alcohol.

・The old village head who asked for Eruna's body as the payment of helping his village.

...etc, they are trapped in the lustful spiral and involved in the incident around Adus Village.

【System】

This is a short RPG built around exploration and H events.

At the end of every day, the player must decide to drink/not to drink the love potion.

Drinking the love potion will increase “Lust,” preventing Eruna from being possessed by the succubus at the cost of being horny and having to resist the sex drive.

Not drinking it will allow the succubus to take over Eruna's body completely. If she keeps that going for several days...

 

The character has H stats which will experience changes after H events.

There is also a “Stats Message” system for Eruna!

This game features “Lust” which increases as time progresses and “Corruption” which increases as H events take place.

As the Lust increases, the cap of the Corruption will increase, making the pure Eruna more and more lustful……!

 

You can also play as the side character Sister Aela to experience the events where Eruna is not present.

Nothing will happen to Aela if she doesn't go through any H events, but if H events continue to happen to her...?

 

Not only the cow costume of the childhood playmate, there are uniquely designed costumes!

In this game, the costumes used by each male character have been set, and the characteristics of the costumes will be better used in the H events.
