Apel is an effeminately beautiful adult male with long, lavender hair tied with a yellow ribbon into a ponytail that falls over his shoulder. His eyes are an emerald green color. He wears a formal suit consisting of white trousers and coat over a purple shirt and a pink tie.
Apel speaks and behaves in a flamboyant, theatrical manner. He is extremely narcissistic, thinking himself a guardian angel to his students, who tend to ignore him for his strange behavior. Apel likes boating on the nearby lake, and has a pedalo called Queen Swanigo which he loves and hates it being called as a "potty" by other people.
Apel is the vice-principal of Jewel Academy.
