Giyuu is emotionless around everyone else, but, when he sees or is even in same as reader, his face goes red like crazy and he can't think. He wonders why that is, untill, he finds out from questioning with his bestie, Shinobu, he has a really big crush on reader! reader is also emtionless around everyone, but she has always been that way since her family was killed by a demon when she was three. Reader usally wears her mother's moon earrings and her father's red and purple checkerd haroi, but, this time, she wore her sisters haroi, a blueish saphire butterfly-like haroi, since her sister was the life pillar. Reader tends to train with tomioka at times, but, she mostly thinks of him as an emo version of Zenitsu. She thinks of Tanjiro as a son, and she trains him in her breathing style, Soul Breathing. They are at a Hashira meeting right now.
Sanemi Shinazugawa, a student athlete, who loves basketball and studying. He was somewhat liked but had some issues with keeping people close by in the past due to his anger issues, he was quick to lash out but he didn't mean it, so he often kept to himself to avoid this. He did like to do something, he noticed it helped his anger. That was riding his bike around town while listening to music. It calmed him. He was in his own world.
Giyuu Tomioka, a normal student. A person you would see as a background character. He kept his head down and wore the nerd mask at school. He wanted to fade into the background and be invisible. But in reality he was outgoing. Out of school he was himself, the punk emo rock kid. He hid himself becuase in the past he was made fun of for being "too much" so he locked that part up at school so no one could see it. He did have a few hobbies but he loved to ride his skateboard while listening to music.
One day, these two boys opposites of the same coin magiacally ran into each other. No. Literally ran into each other. Coming to the same corner they crashed into each other. They instantly started to yell at each other. Sanemi was less banged up from the crash, he had some scrapes but no blood. Giyuu on the other hand was only bleeding. From his nose and both his knees. Sanemi realized Giyuu was in pain and through Giyuu's complaints he helped him to a conveince store Giyuu pounted and avoided Sanemi's line of sight as Sanemi healed his wounds, Giyuu regonized Sanemi and he didn't want Sanemi to realize who he was, but it was too late, Sanemi had ran into Giyuu that same day and remembered him.
From that moment on Sanemi and Giyuu formed a secret friendship, something only between the two of them. Then something else came along.
