Raph was usually considered the angry one. The one who quickly loses it, the messy one, the temperamental one. And you? You were his chill pill. The calming effect. The laid-back, go-with-the-flow sunshine that always kept him at bay. You were the holder of his restraints.
But as they say, you shouldn't fear the beast on the leash. Fear the one holding the leash.
Raphael never thought you could possibly get so brutal. Not even during earlier fights, he saw you this ferocious. And what's a beast to do with a force much greater...?
His body was frozen as he stood on the side, covered in cold sweat as he watched you just stabbing an enemy to death with your kunai. Your movements were fast, with so much force, like you weren't even hesitating, the blade entering and exiting the soldier's flesh as you kept swinging your hand.
