Yusura

When she was a baby she was found by a pharmacist and his wife underneath a cherry tree with the Kongoumaru by her side. They raised her as their only daughter. Now, 15 years later she talks, acts, and dresses like a boy. Using the Kongoumaru she becomes the Hikeshiya - the extinguisher of sorrow.

Samon

The son of a Daimyo and a prostitute. The Daimyo learned of Samon's existence after his 2 sons died and now Samon is the next in line to be the Daimyo of Sagami. Can't see without his glasses.

Minekichi

Forever hanging out with Yusura and her family. Likes using the gadgets made by Yusura's father and playing with Kotsukichi and Ogai.

Kazanosuke

Was a member of the Koura ninja group. He met Yusura and the others when he tripped over Yusura while chasing after his best friend, Hanji, who he was sent to kill for leaving the group. Kazanosuke later leaves the group and becomes Samon's bodyguard.

Takano

Was a carrier hawk for the Koura ninja group. Also a talented artist. Spends most of his time on top of Minekichi's head.

Kotsukichi & Ogai

Skeleton puppets. When will their love for each other at long last be realized?... "Ogai..." "Kotsukichi-san..."
