Baby Princess (ベイビー・プリンセス, Beibī Purinsesu) is a series of Japanese illustrated short stories written by Sakurako Kimino with illustrations by Natsuki Mibu and Yuki Kiriga. The stories were a part of a reader participation game in ASCII Media Works' Dengeki G's Magazine where readers could influence the progression of the story. The project was first unveiled in the October 2007 issue of Dengeki G's Magazine, and ran until the June 2012 issue.
A light novel adaptation written by Kimino with illustrations by Sana Wakatsuki was published in seven volumes under Dengeki Bunko between April 2009 and May 2011. A manga adaptation illustrated by Yasuhiro Miyama was serialized between the May 2011 and August 2013 issues of Dengeki G's Magazine. An original video animation adaptation by Studio Comet was released on July 20, 2011 on Blu-ray as a 3D and 2D edition set with the title Baby Princess 3D Paradise 0 (with special 3D-glasses) and on DVD as a regular 2D edition with the title Baby Princess 2D Paradise 0.
When his grandmother and last remaining relative dies, first-year high school student Yōtarō is orphaned. He ends up being adopted into a family of 19 daughters, each with a different personality, ranging in age from several months old to 18 years old. His adventures begin when he moves in with his "true family".
Note - the author of the light novel got carried away with the idea of having the sisters being a year apart in age. Based on the character birth dates given on the OVA website, there would actually 2 calendar years between when the first and last girls were born in which a daughter could not have been born, and therefore some of the ages given are not consistent with the actual elapsed time. As an example, the youngest girl's birthday (Asahi) is given as being in April. According to the light novel, Yōtarō joins the girls on 25 December, therefore Asahi almost 9 months old then. By the time the events of the OVA occur (in early summer), Asahi would be over a year old and, consequently, the eldest daughter would actually be 20 years old.
