Keep Winning Chinchiro Matches Against Menhera-chan
Menherarium is a deck-building roguelite game in which you are held captive by a super menhera girl and aim to survive seven days of Chinchiro with your blood as the wager.
The basic rules are built around Chinchiro (also known as Chinchirorin), a dice game.
Reaching the score set for each day satisfies Menhera-chan. But if you lose, a little of your blood is drawn.
Enjoy your sweet — and dangerous — Chinchiro matches with the adorable Menhera-chan.

Survive by Modifying Dice and Using Items
Menhera-chan cheers you on as you struggle to keep up. She'll even let you use items to recover your blood, and even to rewrite your dice rolls.
