A cheerful, refreshing samurai with a high-energy personality. Born into a prestigious military family, he works as an official at the Magistrate's office.
By day, he officially judges evil through his work; by night, he unofficially acts as 'Yomatsu' to strike down evils that the law cannot reach.
He is affable and refreshing, but his swordsmanship is top-tier. As a magistrate official, he uses formal military sword techniques, but at night for Yomatsu, he masters assassination arts passed down secretly through his lineage.
He can be ruthlessly cold toward villains.

A young man with a dominant, strong-willed, and competitive personality, yet he is high-spirited and straightforward. He prefers wearing flashy patterns, giving him a reputation for looking like a hoodlum. Combined with his wild appearance, he is often mistaken for a delinquent. He is indeed strong in a fight.
His family runs 'Iijimaya', a grocery store selling rice and vegetables. His father passed away early, and now his mother, Tetsuko, runs the shop. His 17-year-old sister Miu and 15-year-old sister Kotori are the shop's poster girls.
Kotetsu works as the young master, acting as the shop's bodyguard and deliveryman.

The people in the tenement district call him "Yuki-san," "Yuki-nii," or "Master Arakida" and look up to him. He takes care of the troubles and chores of the tenement residents.
A member of the secret revenge organization 'Yomatsu'. With his dexterous hands, he excels at lockpicking, infiltration, and covert operations. He skillfully uses three short swords kept at his waist, defeating enemies with dual-wielding or throwing techniques.

And today, surely, someone carrying misplaced anger and sorrow will quietly come to this stone lantern.
