Shounen Oujo

Even though the series never officially ended, only 34 chapters were released, with no sign that it will ever continue. So for all intents and purposes, it is complete.

Shounen Oujo (Boy Princess) is a shoujo manga by Utako Yukihiro, with the original concept by Zenko Musashino. Albert is a poor boy living in the Queendom of Morrigan, a country where men have no rights and are ruled over by women. Albert and his friend Theodore are abducted by slave traders, but they are soon bought by a rich girl from a noble family. It turns out that the girl is 11-year-old Princess Alexia Lumiere, heir to the throne of Morrigan, who wants Albert, who bears a striking resemblance to her, to act in her place while she is away for six months. Thus begins Albert's life as Princess Alexia.
