Description
Aiko Tokosumi, often called Anko by her friends, is a middle school student and one of the pilots chosen to control the giant robot known as Zearth. She is the daughter of a famous and busy announcer or journalist named Akira Tokosumi. Despite coming from a wealthy family, her home life is marked by distance and neglect, as her parents are often absent and have a poor relationship, leaving her to feel isolated. Her initial desire to become an idol is largely motivated by a wish to receive attention from her workaholic father. She has brown eyes and blonde or light-colored hair cut to her neck, and stands about 150 centimeters tall. A distinctive physical trait is a pilot's mark located on her right ear.

Aiko's personality is complex, blending a proud and sometimes haughty exterior with a fundamentally good-natured and caring heart. She can appear reserved and shy, but possesses a strong inner mental resilience. Although she is deeply shaken and distressed upon learning the full, tragic truth about what it means to be a Zearth pilot, she demonstrates significant psychological growth, refusing to succumb to despair. Her core motivation is the desire to protect others and find a sense of purpose, which becomes intertwined with her quest for her father's recognition and the need to safeguard her fellow pilots.

In the story, Aiko serves as one of the key pilots, being the eleventh pilot in the original manga and the tenth in the anime adaptation. Her role is particularly significant because her battle is broadcast live to the entire world, making her the most famous of the children. Her father, once he discovers her involvement, uses his media connections to transmit her fight, turning her into a public figure and a symbol of the children's plight. This public exposure brings both support and immense pressure, yet she finds the strength to continue fighting even after being seriously injured.

Her key relationships are central to her development. The bond with her father is a primary driver of her actions, and his eventual understanding and support during her final battle provide her with a sense of closure. In the anime, she develops a close and important relationship with a fellow pilot named Kanji, and her dying words express gratitude to him for giving her the courage to fight. She is also a member of the group of fifteen children, bound together by their shared, grim responsibility.

Aiko undergoes significant development from a lonely girl seeking attention to a determined individual who accepts her harrowing fate with courage. In the original manga, she uses her practiced dancing skills, honed from her idol aspirations, to outmaneuver and defeat her enemy in a creative and desperate struggle. In the novel version of her story, her battle is far more psychologically brutal, forcing her to confront the terrible moral cost of her survival, which she does by accepting her actions without seeking forgiveness. Her notable ability is her proficiency in dance, which translates into exceptional agility and spatial awareness during the robot's combat, allowing her to perform acrobatic maneuvers. Her mental fortitude, the ability to face an impossible situation and find the resolve to act, is ultimately her defining strength.
