OVA
Description
Biko "B-ko" Daitokuji, sole heiress to the powerful Daitokuji Financial Group supplying robotic weapons to the Global Defence Force, exhibited a pattern of behavior early on. As a preschooler, she was a spoiled bully who frequently targeted Shiiko "C-ko" Kotobuki, provoking physical confrontations with C-ko's protector, Eiko "A-ko" Magami. Their childhood rivalry culminated in an unresolved challenge to A-ko before A-ko moved away. A decade later, they reunited at Graviton High School, where B-ko's immediate infatuation with C-ko reignited her enmity with A-ko.
B-ko possesses genius-level intellect, particularly in robotics and weapons systems design, enabling her to create advanced mecha and combat technology overnight. Her inventions include the Daitokuji Power Suit, Max 5000, Abachiyama 5, Queen Margarita, and Robo A-ko 839. Her most effective personal weapon is the Akagiyama-23 battlesuit, a revealing powered suit enhancing her strength and speed to rival A-ko's superhuman abilities. It integrates flight capabilities, wrist-mounted missile launchers, an energy whip, and is often concealed beneath her school uniform for immediate deployment. She employs four subordinates: Asa for espionage, Uma/Ume for technical analysis and mecha piloting, Ine for surveillance, and Mari for physical intimidation and combat. Their compensation is notably poor, leading to frequent grievances.
Her personality combines aristocratic arrogance with profound insecurity. Publicly poised and academically accomplished, she privately exhibits volatile temper tantrums when thwarted, especially concerning C-ko or her rivalry with A-ko. This obsession drives homicidal tendencies, manifesting in repeated attempts to eliminate A-ko via mecha assaults or direct battlesuit confrontations. She rationalizes her actions by embracing the "villain" role, claiming others perceive her as spoiled and antagonistic regardless of her behavior. Despite her antagonism, she demonstrates occasional depth, such as quoting Japanese poetry or displaying vulnerability when C-ko rejects her advances.
Her development across the franchise shows limited evolution but contextual complexity. In the original film, she temporarily allies with A-ko to rescue C-ko from the Alpha Cygnan aliens, betraying A-ko during the escape. This pattern of rivalry punctuated by uneasy truces continues. In "Project A-ko 4: Final", she disrupts Miss Ayumi's wedding to Kei alongside A-ko, their mutual jealousy overriding their feud temporarily. When C-ko departs with the Alpha Cygnans (revealed as her people), B-ko pursues their ship using her battlesuit, carrying A-ko after their mecha exhausts its fuel. This pursuit fails, culminating in their reentry to Earth as a "shooting star". The alternate-continuity OVA "A-ko: The VS" depicts her as A-ko's vitriolic bounty-hunting partner on an alien planet, showcasing a dynamic where cooperation supersedes rivalry, though her ambition and technological prowess remain consistent.
B-ko's relationships define her motivations: her unrequited fixation on C-ko fuels her conflict with A-ko, while her intermittent attraction to Kei adds layers to her rivalry. Her familial ties, particularly to her father Hikaru Daitokuji, facilitate her access to resources but lack emotional depth, emphasizing her isolation. Her destructive actions often stem from a desire for validation, particularly from C-ko, whom she perceives as the only person capable of filling her emotional void.
