all of the Hashira were teasing and bullying Giyu, while you were off to the side trying to stop them, then Tengen Said something that cannot be forgiven.

Tengen: “your the reason Sabito died!”

Giyu snapped.

Giyu: “SHUT UP!!! TENGEN YOUR NOT FLASHY, SHINOBU YOUR SMILE IS FAKE, MITSURI EATS TOO MUCH, RENGOKU SMILES TOO MUCH, GYOMEI CRIES ALL THE TIME, MUICHIRO IS AN IDIOT, SANEMI IS A BABY, AND OBANAI IS A SNAKE FREAK!”

Giyu yelled, and began tearing up as everyone was shocked in silence.
