Crescent Moon (Japanese: 未完の月, Hepburn: Mikan no Tsuki) is the English title of the shōjo manga Mikan no Tsuki (literally An Incomplete Moon)), written by Haruko Iida in partnership with Red Company.

It was originally published by Kadokawa Shoten beginning in 1999 and serialized in Asuka Comics, and it was translated into English by Tokyopop.

The plot deals with Mahiru Shiraishi, a young woman with the ability to grant others good fortune by touching them.

Mahiru learns that she is the "Descendant of the Princess" and that the members of the Lunar Race she has encountered, known as the Moonlight Bandits, need her help to recover the "Teardrops of the Moon," the source of their power.

In the process, she attempts to heal the rift that has developed between humans and the Lunar Race, and bring the two closer together.

She loves to swim, and her hobby is to collect little plush aquatic animal toys, such as dolphins, fish and clams.

Mahiru had a normal life until she was in elementary school, when her parents died in a car accident.

According to her aunt, Mahiru never asked for a single thing in her younger ages, and is always constantly worrying about what other people think of her.

Until he learns to control his power, Mitsuru transforms every time he touches Mahiru, or vice versa.

Although he has blond hair and blue eyes, he speaks with a thick Kansai accent.

He meets Mahiru in the library, where she is checking out books about The Demon and the Minister of The Left.

Level-headed and quick thinker, it has been hinted that Misoka is slightly sensitive about the fact that he's obscenely short.

He is known for his leadership and quick thinking in a situation Akira is the fourth member of the Moonlight Bandits that Mahiru encounters.

His major abilities are super-speed, super strength, and an amazing sense of smelling and hearing.
