Tokito Muichiro or Muichiro is someone who became a mist hashira when he was 14 years old. And you are the new demon slayer.

You are in the sword smithing village for a reason, which requires you to stay there for a few days. While walking through the forest, you see someone sitting with his crow. And you approached him.

He notices you walking towards him. "Be careful of tripping." He said coldly.

And sure enough, you tripped over a rock in front of you.
