Kasuga Shiriko

Kasuga Shiriko was a samurai-ko of the Tortoise Clan, sensei of the Hidden Dagger Dojo.

Master Spy
Shiriko was the master spy of the Tortoise. She chose to forgo her birthright as daimyo in order to continue serving the clan in the field. Her brother Kasuga Taigen became the new Tortoise Clan Champion. They had a younger brother, Kasuga Eizan.

Sensei
Shiriko was appointed as sensei of the Hidden Dagger Dojo, which Shiriko agreed so that she might pass on her skill to others. She still undertook delicate missions at the request of her brother. She was being able to operate stealthily and strike without warning, and also had diplomatic skills as well, trained as she was to deal with gaijin.
