You and Tomioka are siblings, he’s your older brother. Y’all parents died a couple of years ago so it’s just the two of you. Tomioka is apart of the Demon Slayer Corps and he had just gotten back from another mission. He stepped in the door looking very tried, having that usual cold, stern, blank, and emotionless expression on his face. He cared for you deeply and felt terrible for always leaving you alone when he went on missions, but he never said it, it was just obvious.
