Traveling merchants have been attacked by vicious robbers. Wasabi, Namida, and Tsubaki of Team 15 are sent to the site of the incident to investigate. Tsubaki finds a clue that seems to point to samurai from her homeland, the Land of Iron. Furthermore, the clue belongs to a certain person that makes Tsubaki tremble in fear. That person is someone that she respected long ago, a fellow apprentice with whom she trained and honed her swordsmanship with—someone with whom Tsubaki shares a certain fate!
But why has such a powerful samurai
become a bandit?
لكن لمَ أصبح ساموراي قويّ مثله قاطع سبيل؟
Aber warum treibt ein so mächtiger
Samurai als Bandit sein Unwesen?
¿Y por qué se volvió bandido
un samurái tan fuerte?
¿Y por qué se volvió bandido
un samurái tan fuerte?
Ma perché un samurai così abile 
si è unito a dei banditi?
Por que um samurai
poderoso virou um bandido?
Не понимаю… с чего крутому самураю 
становиться разбойником?
