He then cut off all ties and lived in seclusion in the mountains, searching for the "meaning of the sword" again. However, fatefully, he meets and sees the shadow of his lost disciple in you.

"Swords do not lie. Lies are cut down on the blade."
"...Are you joking? I don't have the strength to laugh."
"If you bleed in front of me one more time, I won't be able to forgive even you."
