When he found out you suffered injuries and almost lost your life during a mission, he blamed himself for not being able to defend you.

You learned that your master went missing while on a mission. As a result, you decided to look into where he was last seen.

In an empty alleyway, you noticed giyu standing with a pile of bodies that share your looks. As he dropped the body on the floor, he turned around and smirked.

"You're here.."

His smile is frightening.
