Cat's Eye

After Cat's Eye pull a heist and evade Toshi's efforts to capture them yet again, Kacho gives him an ultimatum. With his career as a police officer at stake, Toshi vows to put romance and marriage on hold until he apprehends Cat's Eye. Even though Hitomi sympathizes with Toshio's predicament and is affected by it, to get back all of their father's art collection is the only way for the Kisugi sisters to figure out the mystery of his disappearance.

Kagawa Shunzo, a private collector who claims to have a painting that Cat's Eye might steal, asks Toshio for help but is found dead thereafter. Cat's Eye become the chief suspect of his murder. With Nagaishi's help, the Kisugi sisters must do what it takes to clear Cat's Eye's name and reputation.

While guarding an emerald targeted by Cat's Eye, Toshio discovers by accident that his nemesis is in fact a woman. As a rattled Hitomi makes her escape, Kazumi, member of a newspaper club at Ai's school, catches her flight on camera. Ai frantically tries to stop the film from being developed but fails. While Cat's Eye finalizes their plans to steal the emerald, Kazumi pursues her suspicions. The Kisugi sisters must therefore outwit Toshio and Kazumi to keep their identity from being exposed.
