Swordsmanship isn't Nio's strong suit. He's determined to train with the Miburo regardless, but his clumsy efforts annoy another young recuit: the talented Saito Haijme.

Nio and Hajime confront an assassin who targets Aizu samurai. But unlike any killer they've faced before, he fights for conviction. Do the boys stand a chance against him with their blades or their words?
