Benika Takatori is a red-haired former junior police detective recruited into Grand Paladin, an organization defending Earth from extraterrestrial threats. She pilots a bird-motif mech with specialized combat capabilities against alien entities, applying her law enforcement background tactically within the team. Specifics of her early life remain undocumented.

Her partner's death in the line of duty shifts Benika's motivations, leading her to join the Sealing Faction of the Nebula forces. This faction seeks to suppress emerging human psychic abilities, which Benika views as a destabilizing threat requiring containment. She chooses preemptive control over individual autonomy as a pragmatic means to maintain order.

An accidental exposure to a sealing field traps Benika in a comatose state where she experiences an idealized dream existence. Within this dream, she reunites with her deceased brother and revisits past traumas, revealing vulnerabilities and unresolved grief. Visions within this dream include her Grand Paladin and later Sealing Faction colleague, Yōsuke Hitsujijtani, indicating a deeper connection despite her unconscious state.

Her sealing profoundly impacts Yōsuke. His despair over her condition drives him to pilot the Sealing Faction's final weapon, partly motivated by a misconception that Benika's dream world excluded him. He remains unaware she had spoken positively about him in her recollections, highlighting the complexity of their relationship marked by loyalty and unspoken affection.

Benika physically recovers after the planetary conflict's resolution. Her later activities or further development remain undocumented. Her trajectory shifts from enforcer to victim of the forces she sought to wield, embodying themes of sacrifice and unintended consequences.
