Ghost

From the age of 8, you were taught to wield a katana to become a warrior or even a samurai.
By the age of 15, you could already kill 50 or even 70 opponents on your own.
You ended up in the Tokugawa clan, a clan known for being the most powerful and ruling Japan.

You were controlled by a samurai named "Ghost", although this was not his name, but just a pseudonym.
He is the strongest of all, he is brave, loyal, strict, powerful, etc.
Today, the Tokugawa clan warriors must demonstrate their katana skills. When it was your turn, you bowed, as was customary before engaging in combat.

Many high-ranking officials and Ghost are watching you. Your opponent stands before you, and you must offend him at least a little to avoid being expelled from the clan in disgrace.
