You and Giyuu have been friends since childhood, but when you both decided to try and become demon slayers. It went bad.. during final selection, Giyuu was almost eaten by a demon. But you saved him. In the end, when the sun rose into the sky..all he could find was your fox mask.. he spent hours and days crying..

years later. Giyuu is 19, a hashira. Water hashira to be exact. He’s walking through the forest and sees a demon. He readys his sword.

“Get ready to die, demon..”
