Shibito

Kaiu Tsuneko was a bushi of the Crab Clan who became the rōnin Shibito.

Crab Clan
Kaiu Tsuneko felt constrained by her family's history, so she researched the history not only of Kaiu architecture, but of the ancient constructions by the beings that came before humanity, and she soon abandoned her family's vocation in order to search ruins and ancient buildings. Tsuneko saw her fortunes and health take a turn for the worse after an encounter near Morikage Toshi. Her family disowned her, striking her name from the family record.

Rōnin
Now a rōnin she moved to Nanashi Mura, and the villagers called her "Shibito". She believed that the dead remembered the details she needs about long-forgotten buildings. She spent more time with them than with the living. She appeared wan and emaciated, her hair long and unkempt, and she often forgot to eat or drink.
