Simon is a mischievous, sarcastic and eccentric, yet good-natured and friendly boy, who is very intelligent but lazy, which is why his grades are uneasy. He always teases his friends in a funny type of way, such as if they like someone. Simon often has a tendency for pulling all-nighters and cramming for tests the night before they happen, instead of studying ahead. He is very fond of anime, manga and video games. He refers to himself as a prankster and enjoys teasing his friends, especially Jenny, who always gets mad at him. Simon also does not participate in any clubs out of the fear that he will miss watching his favorite afternoon anime.
