Isawa Kaito

Isawa Kaito was an archer and priestess of the Phoenix Clan and founder of the Kaito vassal family.

Slaying a Demon
Near the dawn of the fifth century a demon appeared in the lands of the Phoenix Clan. This demon terrorized the northern mountain range bordering Rokugan, desecrating shrines and destroying villages, and threw the entire Garanto Province into disarray. Kaito, with only her bow and the aid of the kami, confronted the demon on a tall mountaintop, slewing the demon with her arrow, and then gave her life to trap its spirit, freezing it deep in the bottom of a well.

Aftermath
In honor of her sacrifice, her family was raised in status, becoming a vassal family of the Isawa.
