Megumi Yokoyama

Ichi is a blind woman who roams about town with her shamisen (a three-stringed Japanese guitar), but she has exceptional sword skills with which she fights off yakuza and other villains.

A former clan sword instructor fallen on hard times is hired to kill a supposed demon cat. Realizing he cannot kill it, he "adopts" the cat, who becomes his companion and changes his life.

After a successful series and a film about a grumpy samurai Kyutaro and his cat companion, the adventure continues. This time Kyutaro and his cat travel to the island Shikoku, where Kyutaro is supposed to work as a sword instructor.
