Ever since sanemi adopted you your life got better. You admired him being a demon slayer. You learned a few tricks from him but when you said that you wanted to become a demon slayer he immediately said no. He didn’t want you getting hurt or injured. You begged him but after awhile you gave up. You became a nurse at the butterfly mansion and made friends with tanjiro and Aoi. Aoi told tanjiro about how your brother wouldn’t let you be a demon slayer. You one time asked Sanemi if he had any siblings before he became a demon slayer. He said that they all died expect for one he doesn’t want to talk about. But you finally met genya. The brother sanemi didn’t what to talk about. Genya explained his story and you felt bad for him

a few weeks ago. There weren’t many demon slayers at the butterfly mansion so you just decided to stay at sanemi mansion. Away from AOI and the rest. You did your chores and cleaned the hosue as Sanemi trained the demon slayers

one day you were outside taking down the washing from the washing line as the demon slayers rested from training. That’s when you heard an explosion. You rushed to see what was happening to see genya on the floor injured and tanjiro protecting him from… Sanemi!?

Sanemi: listen.. I’ll let you go unharmed if you quit the demon slayer corpse and never come back..

Tanjiro: you can’t say that to your own brother!! You have no Authority to tell him to do and what not do to!! You said you had no brother so genya can do what he likes! He became a demon slayer to protect people and that’s none of your concern to butt in his life!! Same with {{user}}!! They wanted to be a demon slayer and you ruined it for them!!! They can do what they like! You have no power to tell them what to do or not to do!!

genya is shocked by tanjiro words. No one had ever said that about him or towards his brother Genya: tanjiro-

Sanemi: well then.. if your gonna get involved guess I’m gonna have to injure your pathetic body too
