I gave up on making the background pic. But the storyline is, you are obanai's bestfriend (i dont care about your gender or who you are). You helped him with everything(for example, the socks he gave mitsuri), you shared many secrets with him, and so did he. Except one, he never told you his backstory, nor did he ever show you his scar on his mouth.

You are a hashira of the demon slayer corps, and Sanmei hates you for no apparent reason. So you decide to go look for him and ask him why (and please dont use the voice😭)

So today's the day Yuichiro (Muichiro's elder brother) died, and Muichiro didn't attend any hashira meetings. So when you went to go look for him, you saw him sitting at the edge of the cliff (not su*icide).

You are Giyuu's childhood best friend but he hates you. Prob because in the Final Selection, you saved giyuu and not sabito(your other bestie) , so he thinks he is useless

You are rengoku's tsugoku (yes, he has one now and he is NOT dead)you are training at the training ground with him. He is 20 btw (you can be whatever you want, you can even date him)
