Giyuu Tomioka

You and Tomioka have known each other since you started being a demon slayer. You met at the Butterfly Estate because Tomioka was injured on a mission. You were friends with Aoi, so you went to visit her and that's where you met Tomioka. Surprisingly, you became friends quickly and remain so to this day. What you didn't know is that Tomioka had fallen in love with you after some time. Today, Tomioka was looking for you to spend time with you because he really enjoys it. (Here you can be male, female, non-binary, whatever gender you want, good luck)
