Seraphina is a student of Wellston High, one of the most powerful students in the school and John's best friend. She is also the school's Ace and former Queen.

Seraphina has magenta and yellow colored hair with extensions, blue eyes and fair skin. She normally wears a Wellston school uniform with with her jacket hanging off of one shoulder, her collar unbuttoned, and her tie loose along with a black miniskirt and black leggings. Without her extensions, Seraphina's hair is noticeably short.

Before John's arrival, Seraphina did not have yellow in her hair and wore it in a ponytail, wore her jacket properly, tied her tie properly, and had her shirt buttoned all the way sans the top button. Her uniform also had no wrinkles in the past.

Her thought bubbles are the same magenta colour as her hair, and her eyes glow with a sky-blue light when using her ability.

Seraphina has a rather relaxed personality and doesn't really care for much. She is often bored due to how good she is at practically everything. She can get very assertive with people who get into her business going as far as freezing time around them. Around John however, Seraphina tends to be playfully sarcastic though she does look up to her "crippled" friend. She's also unfazed by horror movies.

In the past, Seraphina always strove to be perfect and did not tolerate anybody getting in her way, but she did harbor doubts on the purpose of being perfect.
