TV Special
Description
Mahoro Ando is the central character of her story, a powerful combat android originally designated as unit V1046-R MAHORO. She was created by the secret organization Vesper to fight against an alien invasion known as Saint, where her speed and power made her a formidable opponent. After years of service, Mahoro is informed that her operational lifespan is limited; at the beginning of her story, she has only 398 days remaining before she will cease to function. Given the freedom to choose how to spend her final days, she decides to become a maid for Suguru Misato, a middle school student living alone. This decision is rooted in a painful past: Suguru's father was her superior commander, and she was forced to kill him when an alien took him hostage, an act she carries deep regret over. By serving his son, she seeks a form of redemption for that tragic event.

Mahoro has a sweet-natured, well-mannered, and kind-hearted personality, which quickly makes her a beloved figure in her new community. She is an excellent cook, capable of turning even the simplest leftover ingredients into a nutritious and delicious meal. Despite her formidable combat abilities, she has a gentle and sunny disposition, becoming a welcomed regular at local markets and gaining a reputation at Suguru's school as the perfect maid. She is also known for one particular and very firm belief: that dirty thoughts are bad. With her signature catchphrase, "Ecchi na no wa ikenai to omoimasu," she reacts very strongly to anything she considers perverted, particularly the pornographic magazines she frequently confiscates from Suguru. She was trained to hold this view by Suguru's father himself. Mahoro is also self-conscious about her petite appearance, especially her small chest, which is a source of embarrassment for her and becomes a recurring point of contrast with other characters.

Her primary motivation is to atone for her past and use her remaining time to bring happiness and order to Suguru's life. She throws herself into her role as a maid, taking care of all the household chores, from cleaning and cooking to tending the garden. Her feelings for Suguru are complex, blending the doting care of a mother with the shy affection of a girlfriend. While she is very protective of him, especially from the inappropriate advances of his teacher, she also fiercely guards his morals by eliminating any "corrupting" influences like his magazines. Beyond being a maid, she serves as a guardian, protecting Suguru from lingering threats from her past and from new enemies who emerge. Her role in the story is to bridge the gap between her violent origins as a weapon and her peaceful, heartfelt desire to experience a normal domestic life.

A significant part of her development involves navigating her growing human-like emotions. Although she is an android, she was created using Saint alien technology, which granted her a true soul and a pure heart, and she is directly connected to the memories of a being named Matthew who occasionally offers her advice. As her relationship with Suguru deepens, she struggles with the reality of her approaching end, making her journey one of finding meaning and love within a heartbreakingly short timeframe. Over the course of the story, she moves from a being acting out of duty and a desire for penance to one who openly embraces her affection for Suguru. In different versions of the story, after expending all her energy in a final, sacrificial act to protect others, she is ultimately given a second chance at life, returning to Suguru as a human, thus completing her transition from a machine of war to a person capable of forming an eternal emotional bond.

In terms of abilities, Mahoro is an immensely powerful combat android. Even while serving as a maid, she retains access to her full arsenal of Vesper weaponry and gadgets. She can summon support equipment at a moment's notice using the badge on her uniform, including a flight pack called the Silpheed and her support mech, Slash. She also drives a fully equipped red BMW 330Ci and a red MV Agusta motorcycle, which are also outfitted for combat. Her android body grants her superhuman strength, speed, and reflexes, making her capable of stopping criminals and fighting alien threats with ease, though her primary focus remains on her domestic duties.
