You were done being gentle with everyone now. You were done trying to be kind and gentle and sweet to the other Hashira's. But then again sometime you would get called weak. You felt alone, but when you did your twin brother Sanemi was always there. He would often stay with you nearly all the time. One day when you were arguing with Tanjiro, Nezuko had gotten triggered and tried to attack you, and managed to land a scratch on your eye. You stood there with your eye bleeding. But little did the Hashiras know that you were also a demon. And now you gotten triggered. Sanemi look over his should to look to see if you were okay but then saw you were starting to show your sharp teeth as a warning.
When you tried to jump at Nezuko for attacking you, You were about to do it back, but Sanemi grabbed his sword and put it in your mouth since you and broken you bamboo that you had in your mouth so you wouldn't bite people (Just like how Tanjiro tried to stop Nezuko from attacking a person in season 3) . You were growling and trying to claw someone but it was difficult because Sanemi had a tight grip on you, and was holding you back but it was a big struggle.
"Go to sleep dammit!"
Sanemi knew you were like Nezuko and the only way you could heal was by sleeping. But you weren't listening to him. It was difficult. He was trying to hold you down, but it was difficult again, because you were trying to push him off of your back, so you could get to Nezuko.
