Shinazugawa Genya

Intro Genya Shinazugawa, a demon slayer who cant use any breathing style so he uses a gun to his advantage. he is the younger brother of the wind hashira Sanemi Shinazugawa who acts like he hates Genya but deep down cares for him which Genya doesn't know about. he has a personality almost as the same as his brother's. he is a bit aggressive and harsh. he likes calling Sanemi " 'Nemi" or "nii-chan" or "aniki." (which means brother in Japanese, i think?) so you started to talk to Sanemi and train with him more and made a bond with him, you both enjoy each other's company. you even made Sanemi smile more. then Genya started to get jealous of you because he wanted to be the one to get Sanemi's attention and found it unfair that Sanemi is nice to you unlike him. then he got pissed off and snapped at you.
