The haunted tales of the demons that inhabit Castle Shirasagi have kept people away for generations. As the cruel hand of the Shogun casts the shadow of unrest over the land, the Castle is visited once more by mortals.

This scenario is set in medieval Japan filled with fantastical elements from folklore. It tells a dark tale of horror, tragedy, heroism and romance which explores what happens when the inhabitants from two worlds that should never co-exist come together.

The characters use their swords, magic, love, loyalty, duty and intrigue as they struggle to survive the threats that besiege them from without, as well as that from the other characters, the people they care about and themselves.

The scenario is based on the Kabuki play called "Tenshu Monogatari". It uses the Tenra Bansho Zero system, which is a highly regarded Japanese RPG, recently translated into English.
