Stab in the Dark

Giyuu left his past behind him, or so he thought. He learns differently when a boy stabs him.

Disclaimer - I don't own Demon Slayer. The inspiration for this was learning that the character book revealed he'd been sent to a relative who was a doctor before he ran away and ended up in the care of his sensei, yet I've not found anything that touched upon that specifically. Also, written for Whump of July 2021 - the prompt being stabbing. Originally posted on Ao3 on the second - contains spoilers for the character book.
