Tokyo Black Cat Girl is very similar to Tokyo Mew Mew. It stars Hime Azumi, who has just been asked out by her crush, named Noda, when she suddenly receives superpowers and is told by Masha (not the same Masha as in Tokyo Mew Mew) that she has the responsibility of protecting the world from the invading aliens called Bagu (translated as "Baku").
At the end of the manga, Noda is attacked by the Bagu's leader. Hime transforms in front of him and, with a bit of effort and her strongest attack yet, manages to save his life. All the Bagu's victims survive, but Noda is angry Hime kept her secret. He walks away from her, only to come back and kiss her just when she's sure he is gone. He says she owes him a lot of lunches, and Hime happily agrees. At the end of the manga, Hime goes off to defeat the Bagu, her secret work and love life both going smoothly.
Production of Tokyo Mew Mew
Mia Ikumi spent a year designing the Tokyo Mew Mew manga before the release of the first volume in February 2001. The story she originally presented to her editors was Tokyo Black Cat Girl. However, the production team decided to focus on five female superheroes, Mia was asked to reconstruct the lead character. She had reservations about the changes, as the character was originally designed for a more dramatic series.
- Tokyo Black Cat Girl is similar to Tokyo Mew Mew in that it also had a magical cat girl as the main protagonist, and the antagonists are also parasitic aliens.
- No colour illustrations were released, though Mia Ikumi has confirmed that Hime's eyes and scarf are pink.
- As Tokyo Black Cat Girl was written before Tokyo Mew Mew, it is possible that Tokyo Mew Mew was based off this bonus story, making Tokyo Black Cat Girl the original and Tokyo Mew Mew the spinoff.
- In the TokyoPop version, the alien name was mistranslated as Baku while the Kodansha translation is translated correctly as Alien Bugs.
