Ms. Takeuchi is the woman who wrote the original Sailor Moon comic books, starting in 1992. The series was first published in Japan in comic magazines aimed at pre-teen girls.

Ms. Takeuchi's first sailor-suited superhero was actually Sailor V. The sailor-suit costume was suggested to her by her editor, based on the girl's school uniforms that are common in Japanese. Later, Ms. Takeuchi expanded the Sailor V idea to a whole team of girls who would fight evil. The Sailor V character was later introduced into the Sailor Moon series and became Sailor Venus.

In a 1992 interview, Naoko Takeuchi was asked who her favourite character was. She replied somewhat bashfully that it was Tuxedo Mask, because she likes a man who looks good in a tuxedo! She was also asked about Umino (Melvin) because he is the only character of that type in all her stories. Naoko said she likes Umino a lot but that she probably wouldn't create more characters like him. She also said he will actually be very handsome underneath his glasses! In another interview, Ms. Takeuchi said that Usagi (Sailor Moon) is the character most like herself, and Haruka (Sailor Uranus) the character least like herself.

An interesting story I heard was that Ms. Takeuchi lent her celebrity status to help raise funds for victims of the Kobe earthquake. Tickets were sold by auction for an event where Ms. Takeuchi drew a caricature of each person and used them as models for minor or background characters in one of her comic books. Apparently, some fans paid huge sums for the chance to meet their idol and have their likeness used in one of her manga.

Naoko Takeuchi has a science degree and worked as a pharmacist (or chemist?) before becoming successful in the world of manga (Japanese comics). She married manga artist Yoshihiro Togashi, (author of Yu Yu Hakusho) in 1998.
