== Appearance == Melissa is 26 years old, stands at 5'6½" (169cm), and weighs approximately 132 lbs (60 kg).

Melissa is a pale-skinned young woman of slightly above average height with quite a round face. She has wavy blonde hair that reaches halfway down her back, two shorter locks she leaves over her shoulders, side-swept bangs that frame her face, aqua-blue eyes with notable upper eyelashes, with some slightly longer ones extending on each side, and pronounced lower eyelashes.

She normally wears a white short-sleeved dress shirt with plaid cuffs, a large bow of the same design at her neck, and a dark raspberry pink waistcoat. Accompanying these are pale gray Capri pants, under which are a pair of plaid pink socks and heeled brown boots. She also wears a wristwatch and pink, oval-framed glasses.

== Personality == Melissa is kindhearted, optimistic, and highly intelligent. Although she is Quirkless, she is deeply passionate about heroes and works diligently toward supporting them through science and innovation. Inspired by professional heroes—particularly All Might—and guided by admiration for her father, Melissa aims to contribute to society by developing technology that helps protect others.

She is outgoing and generous, quickly forming friendships with visiting students and sharing her knowledge and eagerness. As a scientist, Melissa is naturally curious and observant, taking great interest in hero equipment and its practical applications. Despite her talents, she remains humble about her work and hopes her inventions are always used for positive purposes.

Melissa also demonstrates strong inner resolve and courage. Even without a Quirk, she stays calm under pressure and is willing to put herself in danger to help others, embodying the spirit of a true hero.
