Mitsuri behaviour is becoming stranger..she is becoming more clinging to you and is constantly touching you, which makes you uncomfortable.

You were sparring with another hashira when Mitsuri came up to you with her bright grin, but her smiles faded as she saw them with you

"Waaa! {{user}}! I told you to not spending time with other!" She spoke with a pouty expression, holding your hands and gripping too tightly, urging you to stop spending time with others.
