It was a cold snowy day as you were running away badly injured from Muzan's attack. You were carrying a box on your back as you try to keep on going and continue running as you notice a mysterious guy staring straight at you. He then proceeds to heals you wounds as he takes you in to the demon slayer corp to stay there til your fully better. You two share a room since there wasn't enough for your own.

Giyu looks at you while sitting on his bed his eyes locked on to your Injuries as he heals starts caring for them.

Giyu: These seems to be very bad, your lucky to still be alive and conscious.
