OVA
Description
Kei is one of the two main protagonists of this series, serving as a Trouble Consultant for the Worlds Works and Welfare Agency, also known as the 3WA. In this continuity, she is a seventeen-year-old junior auxiliary agent who hails from the colony planet Workoh, having been born on January 1. Her physical appearance is characterized by her red hair, which features bleached blonde bangs, and she has an athletic, lean build.

In terms of personality, Kei is hot-headed, impulsive, and often rude, leading many to mistakenly describe her as a tomboy or even assume she is male, a misconception she is quick to correct with physical force. Her typical approach to a crisis is to shoot first and ask questions later, demonstrating a clear preference for direct and violent solutions. She becomes very excited by the opportunity to use large weapons, with her primary tool of choice being a blaster. Despite her aggressive tendencies, she is not without insight and can demonstrate cleverness when properly motivated, though her volatility is often tempered by her partner's more contemplative nature.

Kei has a distinct set of preferences that reflect her rough-and-tumble character. She enjoys cheap thrills such as jet coasters, fast-food restaurants, drinking beer, sushi, and big-game fishing. Conversely, she dislikes wearing dresses and becomes uncomfortable when forced into feminine attire, as seen when circumstances required her to wear a schoolgirl skirt. Despite her fearless and brash exterior, she harbors a notable vulnerability, as she is completely terrified of supernatural entities like ghosts, zombies, and vampires. She also tends to hide her softer side, although it does emerge in rare moments, such as when she protected an infant by allowing it to suckle her to keep it quiet from pursuing assassins.

The character's background reveals that she was on her fourth probation when she was paired with Yuri under the codename "Lovely Angels". The two shared an instant dislike for each other upon meeting, and their relationship began with significant friction. Kei initially refused to work with Yuri and even went so far as to resign from the 3WA. However, during the "Siren" crisis, she returned just in time to save Yuri's life when her replacement partner had quit. This event cemented their partnership. While she frequently flirts with men and gets into arguments with Yuri over the latter's "girly" attitude, Kei's most significant relationship is with her partner. Despite their constant bickering, she is always the first to support Yuri in a crisis, and it is clear that her deepest loyalty and care are reserved for her. Their missions together consistently result in massive collateral damage, which earns them the infamous nickname "the Dirty Pair". Her role in the story is defined by her partnership with Yuri as they take on various assignments, including bounty hunting, assassination, and diplomatic missions for the agency. As a result of their notorious reputation for destruction, whole planets have been known to begin evacuations upon hearing of their arrival, forcing the pair to travel discreetly whenever possible.

Regarding her abilities, Kei is an excellent fighter, a trait that is enhanced by genetic modifications. She is highly proficient with a blaster, which she uses as her primary weapon in combat. Her impulsive nature and talent for causing destruction are balanced by her partner's more level-headed demeanor, creating a dynamic duo that is effective, if chaotic, at solving problems.
