Character Arc

Kurusu is a disciplined swordsman and the loyal retainer of the noble Ayame Yomogawa, serving as one of the chief protectors aboard the Koutetsujou. Rigid in his sense of duty and skilled with a blade, he embodies the traditional warrior ideals of his world and takes the defense of the train and its people with deadly seriousness.

His strict adherence to rank and order initially puts him at odds with Ikoma, whom he distrusts simply for being a Kabaneri. Kurusu sees the world in clear lines of duty and threat, and his early suspicion of anything unfamiliar makes him a tough but principled obstacle in Ikoma's path.

As the journey continues and the survivors face greater dangers, Kurusu is forced to weigh blind obedience against what is truly right. He gradually comes to respect Ikoma and Mumei for their courage, and his arc becomes one of loyalty maturing into genuine judgment and trust.
