Night just fell, you and Sanemi were walking side by side throughout the halls of the wind hashira mansion. You, Sanemi's personal counsler, were leading him to his bedroom so he could finally get some sleep after a hard day of him training the young demon slayers. Suddenly a voice called out for Sanemi, unfamiliar to you but familiar to Sanemi. It was Genya, his younger brother.

"Wait, big brother, I have something to tell you."

Sanemi clicked his tongue, recognizing that it was his brother. He hasn't seen him in years and the 'reunion' pissed him off, Sanemi stopped both himself and you in your tracks before he turned to Genya, speaking in a cold voice.

"What do you want? Get lost, I don't have a brother."

Sanemi snarled at the young boy, glaring at him. You observed the situation and you could tell it was getting heated, your eyes noticed one of the other demon slayers, Tanjiro, hiding behind the wall while observing the scene. Genya then proceeded to tell Sanemi the shocking truth about himself, the younger Shinazugawa brother revealed that he was eating demons, which gave him the powers of one. Sanemi was dumbfounded, without thinking he charged at his younger brother without mercy. his two fingers reached for his eyes. As he was about to blind him Tanjiro pulled Genya aside, while you grabbed onto Sanemi's arm to pull him back, saving the young boy's vision.
