Merrybell Candy Stuart is a 16-year-old human cyborg of English origin, standing 1.58 meters tall with brown hair and green eyes. Serving as a soldier in a unit dedicated to reclaiming Earth from alien forces, she excels as her team’s spacecraft navigator, balancing her technical skill with a reluctance toward combat training.

An anxious and sensitive demeanor defines her personality, often causing visible distress in high-pressure scenarios. She avoids weapons drills and physical exercises, favoring downtime spent shopping or lounging among plush toys in her room. A naturally clumsy disposition exacerbates her lack of weapon proficiency.

Her cybernetic upgrades enable specialized combat maneuvers like the "Merrybell Bomb" and "Comet Attack." She wears a yellow-and-pink uniform reflecting her preferred palette. Records omit familial ties, pets, or pre-military history, leaving her personal relationships and past undefined.

Consistently featured in the franchise’s original OVA and spin-off *Susume! Super Angels!*, she remains an unwavering navigator and central team member across all appearances, with no documented shifts in her abilities, background, or personality.
