At last, Kenshin faces off against Aoshi Shinomori, the head of the Oniwaban Group. In the Bakumatsu Era, the battle-obsessed "Oniwaban group" lost their meaning of existence after surrendering the castle they served without even being able to fight. Aoshi is unable to bear this regret and is in earnest pursuit of the title of the strongest warrior. As a former Revolutionary warrior, Kenshin cannot tolerate conflict without morality. Two men who made killing their profession in the Bakumatsu Era clash against one another, putting their pride on the line.
Our only regret is the fact
that we could not fight.
.ندمنا الوحيد هو حقيقة عدم قدرتها على القتال
Das Einzige, was wir bedauern, ist,
dass wir nicht kämpfen konnten.
Nuestro único arrepentimiento
es no haber podido luchar.
Aunque sí siento rencor por
no haber podido luchar.
On regrette seulement
de ne pas avoir pu en découdre.
Il nostro unico rimpianto 
è non essere riusciti a combattere.
Nosso único arrependimento
é não ter podido lutar.
Мы жалеем лишь о том,
что не скрестили ни с кем клинки!
