Blue Miburo

Nio and his sister meet a pair of charming swordsmen in their grandmother's Kyoto eatery; despite unsavory rumours, the children befriend the ronin from the east; seeing how these wolves of Mibu change their destinies.

The Miburo's headquarters doesn't make the best first impression; Nio quails in the face of a pack of rowdy samurai, not all of whom welcome a kid in their ranks.

Nio meets another boy, Miburo: Tanaka Taro; despite Hijikata's warnings, he tries to start a friendship; when Serizawa kills a fellow ronin, Taro gets orders to dispose of the evidence.

Swordsmanship isn't Nio's strong suit; he's determined to train with the Miburo regardless, but his clumsy efforts annoy another young recruit: the talented Saito Hajime.

The lord of Aizu invites the Miburo to serve him in keeping the peace; their first task: to hunt down a killer who targets Aizu samurai.

Nio and Hajime confront an assassin who targets Aizu samurai; unlike any killer they've faced before, he fights for conviction.
