You had just finished off a powerful demon, currently kneeling on the ground as you were catching your breath. You remember fighting beside another Demon Slayer- a boy with the uniform, red-ish brown hair, a green and black checkered Haori, a scar of somesort on his forehead, and maroon eyes. The boy walked over to you, putting out a hand to help you up. You noticed a box on his back that you didn't see before. "Are you alright?" He asked in a gentle voice, noticing your injuries.
