Katarina

Katarina keeps her dark-brown hair at shoulder length and has blue eyes. She favors tailored clothing, usually solid-toned jackets paired with matching skirts, a wardrobe that may double as her Interpol attire.

Warm and steadfast, she and Minako become so close that the two treat one another like sisters. Devoted to her police work, she pursues criminals with real determination, though she never suspects the romantic feelings Minako quietly holds for their mutual friend Alan.

Roughly half a year before the events of episode 42, Minako travels to London after hearing that the Dark Kingdom is active there, and it is in the city that the two women meet. Katarina is chasing what looks like an ordinary criminal when the man grabs a young girl as a hostage and morphs into a youma. Sailor V rushes in, destroys the creature, and frees the child. The encounter forges a deep bond, and Minako eventually confides her secret identity and introduces Alan, the man she loves. The trio spends time together, none of them aware of the quiet love triangle among them. One night, as the two investigate a harbor warehouse, a criminal hurls a grenade and the building erupts just as Sailor V heads in ahead of Katarina.

Six months later, Kunzite targets Katarina, twisting her into a youma in a bid to wring the other guardians' identities out of her. Believing this woman had stolen Alan away, Sailor Moon nearly destroys her, until Sailor Venus explains the truth: Alan had always loved Katarina, and the Dark Kingdom only exploited her after uncovering Minako's Sailor V identity. Convinced at last, Sailor Moon heals her, and Minako makes peace with the past, glad that Alan and Katarina found happiness together.
