Cat

Cat is a cat best known for her relationship with Nobody. Upon meeting him, Cat first believed Matthew to be Marik.

Nobody
Nobody is Cat's boyfriend, making her the loneliest girl in the world. The two met in high school and bonded in part over their mutual interest in Pokémon.

Matthew
When Cat first met Matthew, she asked him whether he was Marik. This astounded and offended Matthew, as he could not believe that she believed him to be a communist. Matthew's opinion of Cat remained relatively steady since that incident, though she would occasionally join in on Nobody's nonsense, much to Matthew's distaste. In 2021, Cat texted Matthew a photo of a spider that she thought was "cute", which caused him to drop his phone and lose a great amount of respect for her.
