Marmalade Boy is a shōjo manga by Wataru Yoshizumi. It was published by Shueisha in the magazine Ribon from May 1992 to October 1995 and collected in eight tankōbon volumes. The manga was published in English by Tokyopop, which also licensed the anime series. Tokyopop has since lost the license to the manga series, as Shueisha refused to renew it, leaving the releases out of print.
Marmalade Boy first premiered in the May 1992 issue of Ribon where it was serialized monthly until its conclusion in the October 1995 issue. The 39 unnamed chapters were collected and published in eight tankōbon volumes by Shueisha starting on December 12, 1992; the last volume was released February 20, 1996. Shueisha later republished the series in six special edition volumes. The first special edition volume was released on March 15, 2004, with new volumes published monthly until the final volume was released on August 11, 2004.
The series was licensed for an English language release in North America by Tokyopop. The individual chapters were serialized by the company’s manga anthology, Smile, from December 2001 through April 2002. Tokyopop released the first collected volume of the series on April 23, 2002, releasing new volumes monthly until the final volume was released August 5, 2003. It was one of the first manga series that Tokyopop released in the original Japanese orientation, in which the book is read from right to left, and with the original sound effects left in place. Tokyopop’s volumes of the series are out of print. Shueisha refused to renew the company’s license of the series after becoming part-owner of rival publisher Viz Media. It is also licensed for regional language releases in France by Glenat, in Mexico by Grupo Editorial Vid, in Spain by Planeta DeAgostini Comics, in Italy by Planet Manga, and in Germany by Egmont.
In the week of March 31, 2013, a sequel to Marmalade Boy titled Marmalade Boy Little went on sale in the year’s fifth issue of Cocohana. While Miki and Yuu make appearances, the new series, set 13 years after the end of the earlier one, focuses on Rikka Matsuura and Saku Koishikawa, Yuu and Miki’s respective sister and brother.
Miki Koishikawa’s ordinary life as a sophomore in high school is turned upside down when her parents suddenly announce that they are getting divorced in order to swap partners with a couple they met back in Hawaii. They seek her approval of the shocking change, and while at a restaurant during dinner where Miki meets the other couple as well as their teenage son Yuu Matsura, who is around her age, she reluctantly agrees to the arrangement. At first, Yuu appears to be a complete jerk who takes every opportunity to make fun of and tease Miki, but he actually turns out to be fun and attractive, and Miki finds herself falling in love with him. Little by little, she accepts her new family arrangement and opens up to Yuu as they become best friends.
After a while, Miki and Yuu’s relationship starts to become complicated because of the former relationships that they’ve had and developed with other characters. These include Miki’s long time classmate and former crush from middle school, Ginta Suou, and Yuu’s former girlfriend from his previous school, Arimi Suzuki. A secondary subplot develops when Miki’s best friend, Meiko Akizuki, herself starts to have her own problems because of the relationship she has gotten into with one of the school teachers, Shin’ichi Namura.
Throughout the series, Miki and Yuu’s relationship is further developed and tried, influenced by the other characters around them and the relationships that they develop with these characters.
