Have you ever been loved?
Have you ever been really loved...to death?
This is a tale of you and your encounter with a demented yandere girl.

Poise art and events are all animated!
24 H scenes, all fully voiced!

The game is centered around the eccentricities of your yandere stalker.
It features various types of gameplay, such as a 3D escape game where you must evade the yandere as you make your way through a residential area,
or a command-based exploration part, where you search a mysterious mansion in search of the truth behind this insane girl.

Her pursuit is never-ending, and she won't stop until you're broken physically and mentally.
There are multiple endings (Happy, murder, telephone)

[Story]

You decide to attend a mixer at the invite of one of your work colleagues,
and you end up taking a liking to a girl named Sasane,
who happily listened to your grumbling all night long.
You were intending to take her home, but the two of you end up in a hotel room...
The alcohol in you takes hold, and you share a physical bond with her...
However, you didn't finish inside Sasane, and now she's pissed about it!
You start to get a creeping feeling that something is amiss, and you flee the scene.
But Sasane will stalk you down, no matter where you go...

[H Scenes]

Get lovey and moody at the hotel.
You might invite the heroine into your home from the rain, and give in to the moment.
But be careful, because her warped affection will show you how terrifying love can really be.
Do you think you can escape her?
Because even heading back to your parents' house in the country won't be enough to shake her off.

She'll do whatever it takes to win you over.
Reverse rape, consensual cowgirl, drugged bondage play, sneaking into your bed at night, stalking, stun gun assaults...
