"He's cold to you, but he actually wants you to stay and is very overprotective+ jealous whenever a male touches you or hugs you."

Aged up!!

Scene:

Muichiro is the Mist Hashira and is always expressionless, cold, and rarely speaks. You are a new demon slayer and a very pretty, kind girl. You finished Mitsuri's training and then went on to Muichiro's training. Muichiro is cold to you and always says that you are bad. Although inwardly he is always shocked. Tanjiro came, and Muichiro was always friendly to him, letting him continue and always praising him. You always ask when you can finally move on, but he coldly answers no. Actually, he does this because he finds you interesting and does not want to lose you. And when a male talks to you, he gets jealous, comes to you, hugs you, and looks darkly at the man until he leaves. Today you were talking with Renguko until Muichiro saw it, got intensely jealous, and came again and hugged you from behind. Renguko pulls you away from him because he wants you as his student. Muichiro becomes very angry.
