Demon Girl's Level Drain Revenge

One day, a suspicious drug that became popular among students from the black market...
It's called "Futanari medicine."
This story takes place in Kivotus in this medicine and among the girls.
 
In vol.1 Satsuki x Gehenna mob (Futanari), Asna x Bani mob (Futanari), and Hanako x Koharu (Futanari) appear.
Each one is included in two videos.
Only one side is Futanari.

This is a Story of "Love"
One day, Hitomi Tadehara, the best friend of Ichika Shinonome, committed suicide right before her eyes.
"I'm sorry for hurting you so much, Ichika-chan."
"If I could start over with you, I'd like to have a normal romance this time."
Though Hitomi should have taken her own life, one day she naturally reappeared in front of Ichika.
From that day on, Ichika began to be consumed by Hitomi's twisted affection.
Classmates who interfered with Ichika's love were killed by Hitomi, and Ichika herself was gradually tainted by Hitomi's warped desires.
Can Ichika accept Hitomi's love?

Deck-building x Status Effects x Defeat
There's always that one card that throws a spanner in the works when you're playing games with a deck-building element.
Use them, they'll mess something up. Don't use them, they're even more of a pain in the ass.

You end up forced to use them by your opponent's actions.

Forced by the rules of the game to "use" or "lose.
Or perhaps you'd be tempted to use cards with disadvantageous effects like "seduction"...

...once you're completely sucked in, it's already too late.
Before you know it, you'll be hanging off the precipice with no way back, accumulating tons of different status effects, and having cards taken right out of your deck.
There's even some out there that will control your very soul.
 
Lose and the search is over
In pretty much all of our previous works, if you lose, you could continue on.
But not in this game.
Lose, and the search is over. You'll be returned from whence you came.
Losing here would mean it was all for nothing...
You're so close to victory, but if you're unexpectedly seduced at a time like this...

Your parents leave overseas for work, and you're home alone with your stepsister, Kurumi.
Kurumi is a bright and energetic girl who loves to tease you.
She knows exactly how to flirt and be naughty around her virgin older brother.
Even if it's just by marriage, you know you shouldn't get involved like that with your sister, but...
You might just give in to the cute Kurumi and cross a line that's forbidden to an older brother...

Hired as a temporary teacher in an acadelt for demons, you'll act as the demon raiser
of very unique demon girls. Sometimes you'll play with them, sometimes you'll eat with them,
and sometimes they'll eat you up...
This RPG is a bit of a risky teacher experience, but with demons.

Playtime, mealtime, naptime, snack time...

While taking care of the succubi at the Demon Garden, you must understand each
demon's preferences and personality, deepening your bonds with them...
or failing to get along, leading to the demons losing their affection
for you and milking you dry of semen as "food"...

The outcomes of each interaction with the demons vary depending on your relationship with them.

Will you deepen your affection and enjoy an ideal and joyful life with the demons?
Or will you endure a humiliating life as a toy for demons who dominate you?
It all depends on your actions...
