I've been doing a few things based on the anime and manga Princess Resurrection (Kaibutsu Oujo) lately, so I thought I should say a few words about it since I don't think it's all that well known. It's a fun popcorn sort of show that I really enjoy, despite the fact that it is pretty cheesy at points.
Hime is the daughter of the king of monsters, who rules a realm parallel to the human world. Members of the Royal Family are very much like ordinary humans as children, but become immortal when they reach maturity. In order to avoid power struggles between immortals, each generation of the Royal Family must fight each other for the throne. The battle involves assassins, duels between Royal siblings, and overly convoluted plots. The last one left alive gains the right to claim the throne.
Hime moves to the human world at the beginning of the series where she lives in a mansion on a hill overlooking Sasanaki City. She hires a live in maid named Sawawa, who brings her little brother Hiro to live with her. We begin with Hiro arriving by himself in Sasanaki City and following directions in a letter from Sawawa to the mansion. On the way, Hiro encounters a mysterious and beautiful woman (you'll never guess who this turns out to be) and her child like android servant Flandre. Hiro promptly gets himself killed, either by being hit by a van that swerved to avoid Flandre in the manga, or by being crushed by steel beams falling from a construction site in the anime. Fortunately for Hiro, Hime and other members of the Royal Family have the ability to resurrect the dead and turn them into immortal servants. The main cast is rounded out in the next few episodes as Hime befriends the werewolf Liza and the vampire Reiri.
Princess Resurrection is mainly episodic, with an action comedy sort of feel, with more emphasis on the comedy. Nobody's going to claim that this series is going to save anime, but it's fun light entertainment. The series has the blessing of Universal Studios, and frequently features classic movie monsters such as the invisible man, triffids, and the mummy.
My attempt at a Princess Resurrection doujinshi starts here.
