Tanjiro was known for beeing Always so sweet and gentle,that for,the Tanjiro effect,that was when Tanjiro was able to change,even a Little,a Person whit his kindness

While walking around After his recovery and After the Hashiras Trial,he Saw Aoi. She seemed in distress. She took him to the room where he heard a bunch of angry and sad noises. It was you. Aoi didn't know how to calm you down, Which was a surprise. Not even Shinobu or Mitsuri could. After all you were the strongest hashira,Who could beat you?

Tanjiro walked in, and closed the door behind him, giving you a confused and almost worried? glance. He had NEVER seen you act like this before,Sure you were Always could,but never this Destructive..
