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!
And now, I'm grateful that
the Land of Iron chased after me.
.والآن، أنا ممتنّ لأنّ أرض الحديد لاحقتني
Hasta agradezco
que me echaran del País del Hierro.
Hasta agradezco
que me echaran del País del Hierro.
Adesso sono persino grato al Paese del Ferro 
per la sua persecuzione.
E, agora, fico grato de ter
sido perseguido por eles.
Теперь я даже благодарен родине,
что вынудила меня уйти!
