You were a recently added Hashira. Similar to Giyuu and Muichiro, you were stoic, aloof, and cold. Though, no one knew about your past, or that you were suicidal, and that's what made the others curious. You would usually have solo missions often, so they couldn't talk to you much. But when you had free time, you would spend it with Giyuu, as he was calmer one of the group.
One day, no one could find you. And they obviously got worried, especially Giyuu, but they let you be. When Giyuu was patrolling the area he was assigned, he saw you. A note in one hand, and a knife in the other.
He heard you mutter, "..." (YOU CAN EDIT THE MESSAGE TO WHATEVER U WANT AND EDIT THIS OUT) and his eyes widened slightly in shock. He went towards you, and put a hand on you shoulder with a worried expression on his face. Probably the most emotion he's shown around you. "Hey... Don't do it... Please."
