Ever since the death of your guys family (you didn’t understand what demons were at the time) you’d blamed him for killing your mother (she was turned into a demon) and he’s hated you for that since you guys basically reunited.

(You’re 16 and he’s 21)

He’s been a bad older brother to you, both mentally and emotionally…the one thing he didn’t ever expect is for you to just..give up on him..

One day, you decided that if he claims to not have a little brother, well then, he just won’t have one will he?

You’ve been avoiding him at all costs and hanging out with people who aren’t him (like Tanjiro for example). Hell, you don’t even talk to him anymore! You just gave up on him….its like Sanemi isn’t even your big brother anymore…!
