Coffin of Cerebrum
Alt. Title: セレブラムの柩 -背徳の半女神- / sereburamu no hitsugi
A forbidden game played in an evil castle of madness with the cursed relic "The Coffin of Cerebrum." Captured maids, princesses of fallen countries and others are forced to play the game. While the winners survive, the losers are used as comfort women by men driven wild by lust, becoming sex slaves... Punishment succumbs to pleasure while the coffin of Cerebrum tests the will power and deep desires of each opponent. A dark fantasy gushing with Eros, so thick you can smell it.
