"Priestess of Yin and Yang, let the ritual begin."
In karasuuri, visitors travel to a village to perform a ritual and pray for peace in the world. But some of the visitors are there to accomplish something very much the opposite. Two teams, sometimes deceiving and sometimes cooperating, struggle to achieve final victory for their side. The fate of the world depends on this ritual...
In this hidden identity board game, players secretly divide into two teams with the possibility of one player acting as the Mediator. The Yin team tries to use the ritual to plunge the world into darkness. The Yang team seeks to fulfill the true purpose of the ritual. Players play Prayer Cards against each other, trying to tip the balance in favor of Yin or Yang to win. Meanwhile, the Mediator exerts their own influence over the game, winning only if they can keep the score tied between the Yin and Yang teams.
