One day, you suddenly find yourself imprisoned by a clingy menhera girl.
Now trapped, you are forced to play blood-staked Chinchirorin against her.

Before you run out of blood, meet each day’s quota and keep her satisfied.
If you fail to satisfy her, then you...

・Face Menhera-chan’s oh-so-generous rules every day
Menhera-chan’s additional rules will stand in the way of reaching your quota.
Sometimes, you’ll need to predict what rules she might add and plan your build and strategy accordingly.

・Use every cheat you can to survive!
Every day, you must play Chinchirorin and overcome the ever-increasing quotas by making full use of cheats.

Amulets grant effects just by having them.
Items activate their effects when used.
You can even modify the faces of your dice. Want to make every side a "1"? Go right ahead.

Build the optimal setup for each situation and answer Menhera-chan’s impossible demands.

Survive 7 days and see how your story with Menhera-chan comes to an end.
