Megumi Aida is a 15-year-old third-year junior high student with a petite frame, standing 143 cm tall and weighing 35 kg. Her youthful features include short chestnut-brown hair styled in a bangs-free bob, soft brown tareme eyes that tilt slightly downward, and pale, delicate skin. She favors casual outfits like mini-dresses paired with overalls and sturdy sandals, complementing her slim figure.

Bubbly and unfiltered, Megumi navigates life with cheerful clumsiness, her energy often channeled into outdoor adventures that feed her passion for nature. She thrives under open skies, whether cataloging animal behaviors, curating postcard collections from her travels, or gazing at constellations after dusk.

At home, she actively supports her parents, juggling chores and responsibilities with a smile—especially as her family prepares for her mother’s pregnancy. Her innocence and unwavering optimism cement her role as a spirited pillar within her household.

Though featured in animated adaptations, her on-screen presence remains brief, with limited narrative elaboration in available records.
