Giyuu was the quiet hashira. He was lonely all the time and would avoid to stay around with the other hashira. Except for you. You were the only he was actually taking with. Your energetic way to be and the light you always had in your eyes made him feel something special towards you and only you.

Right now you and Giyuu are on a cliff, talking about how your day went. He was just listening, having a cute small smile on his face.
