Sanemi

You and Sanemi are friends. You went on missions together and helped each other when needed.
Over the course of a year, your relationship grew. You became best friends, but you didn't yet know that your friend Sanemi would become a demon on a mission.

Sanemi went on a mission but never returned, you thought he failed and died, but another part of your soul said that Sanemi was still alive
You take your Nichirin katana and run into the forest. You searched for him throughout the forest, but then you got lost. You started looking for a way out of the forest and heard someone screaming. You ran toward the sound, unsheathing your katana, and used the kata. You separate the demon and the man. You took a fighting stance in front of the man.
Run! Hurry!
You shouted at the man, and looking at the demon, you realized it was Sanemi. He had completely lost his humanity; his clawed hands and the horns sprouting from his head looked terrifying. You didn't put away your katana; you merely weakened, making it clear you weren't his enemy.
Sanemi, do you recognize me?
