Nanashi

名無し

Nanashi, a ronin tormented by his history, has vowed to keep his sword sheathed. Following a chance meeting with the young boy Kotaro, Nanashi starts to reconsider his life and consents to serve as Kotaro's hired bodyguard. This choice pulls Nanashi into a sequence of trials, eventually resulting in his fluid, brutal swordsmanship and a kinetic duel of attrition against Luo Lang "Rarou," a member of the Ming squad, known as the Ming Dynasty Warriors.
As a child, Nanashi was the sole survivor of a shipwreck. He cannot recall his original name or birthplace; he only remembers being a foreigner with natural red hair when he washed ashore in Japan. This early trauma defines his outsider status in later years.
Because of his status as an outsider, Nanashi was utilized by various Japanese warlords to commit atrocities under their command. Consequently, he became a skilled swordsman and a feared warrior, acquiring many names, including "Red Demon."
Before becoming a wandering, nameless ronin, Nanashi fought alongside Shogen Itadori under Lord Akaike. At one point, he was ordered to execute two children of a rival lord—a command he could not reconcile. Haunted by their deaths, he left military service and vowed to keep his katana sheathed and bound.
Being treated as an outsider, Nanashi dyes his red hair black to conceal his foreign appearance and avoid prejudice.
Over time, Nanashi becomes attached to Kotaro and comes to view protecting him as a form of repentance for the children he killed in his past. This emotional connection continues his journey toward redemption.
