A third-year student in Heartslabyul and its vice-dorm leader. Trey is calm and mostly kind to his fellow students. He also is rather good at cooking, which Ace and Deuce are amazed by. Due to this, Trey often makes sweets for Riddle, who is his childhood friend. Trey also has a habit of backing up Riddle with the rules he enforces, despite him not necessarily agreeing with them.
