This RPG specializes in one-on-one combat. It develops only in the conversation/preparation part and the battle part.
The battle is a turn-based command battle.
Four types of striking techniques: Hi, Mid, Low, and Jmp,
The superiority of the attack is determined by the three systems of strike, grapple, and guard, and the advantageous side's technique is performed.
The game unfolds like a fighting game, requiring the player to keep track of the HP, EP, and ST (Stamina) gauges.
The more attacks you hit in a sequence, the higher your level and the more powerful your moves will be.
When ST is reduced, the opponent can be downed, and you can follow up and recover.
Of course, the opponent will also use powerful and sneaky techniques.
New equipment and techniques can be acquired with the DP gained from each battle.
But Ivilla also gets stronger with each battle and learns new techniques. More than 30 of them!

This game is rated R15 and is not an erotic game, so there is no taking off of clothes, foreplay, or sex.
However, we have tried to create a slightly erotic experience that can be enjoyed only because it is not an erotic game. I think that the sight of girls fighting each other and being beaten by each other are very attractive, and I don't think there are many games that can satisfy such a niche fetish, so I created this game.

Ivilla performs a variety of fetish techniques.
The strong point of this work is that the female alien performs exciting technique on the girl android.
As I believe such works are rare in the world, I have made an effort and attempted to localize it into English.
Lead Valcute to victory against Ivilla's evil attacks!
