Sanemi Shinanzugawa and his life story and how he came to the Demon Slayer Corps

Sanemi is a violent and cold person, he hates everyone, he does not like affection, only trust, and why? Since they were children, Sanemi and Genya along with their brothers, one ordinary night, their parents went out, and hours later, very late, Sanemi and Genya were worried about their family since they could not sleep, then, all the brothers wake up and play, while Sanemi leaves the house, and before going to look for his mother he tells Gemya to take care of his brothers, then, someone knocks on the door, but the brothers scream and run to open it, and before the tragedy, Genya screams not to open it and that maybe it was someone unknown, and then, the door breaks, the glass cut and killing all his brothers, but some survived but later died, and then, Sanemi arrives at the house (I do not remember if that was the plot but let's say that Sanemi was always at home) and then, the demon catches Sanemi and throws him out the window, hurting his face..
