This is a review for the entire series (two volumes).
"Princes Knight" is often described as a proto-feminist work, and the starting point for shojo manga (Japanese graphic novels targeting young girls). It is one of the earliest works of renowned Osamu Tezuka, so I approached it with high hopes. However, it was written in the 50's, with all the biases of that age, and it has not aged well. The premise is somewhat promising: a baby, with a female body, is accidentally given a boy and girl heart in heaven, prior to birth. This baby, Sapphire, is born as the sole heir of a kingdom and is raised as a prince, hiding her true gender from everyone since the law dictates that only men can reign (and yes, several characters point out that law is misogynistic). So far, so good, except...
* The fictional God in this world feels that a person having both a boy and girl heart is something that needs to be fixed, and sends a cherub to retrieve the boy heart.
* Sapphire is very skilled with a sword, but when her boy heart is removed in the middle of a battle, she loses all her strength and is not able to fight at her skill level.
* A witch seeks Sapphire's girl heart for her daughter in order to make her more domestic and subdued
* Much later on, another character points out that the king could have changed the law at ANY time, and not have forced his daughter to have to go through that charade
* Near the end of the work, women go on a strike and later on, battle. Men are dismissive of their ability to fight, and only relent because they want their laundry done.
* When female characters want to get the attention of a prince, they highlight their demure behaviour and domestic skills.
* When the boy heart is given to a mindless fool, he suddenly becomes stronger, intelligent and articulate.
Ughhh. I could overlook most things due to the mindset of the time, but the core belief that boy heart = strength and intelligence, and girl heart = weakness and nurturing is something I cannot stomach.
This is a fairy tale, with heavy influence from Walt Disney, both in the artwork and some plot elements. Some of the panels depicting forest creatures could have come straight out of an old school Disney movie. This is not a surprise, as Osamu Tezuka acknowledged the huge influence Disney had on him. And while the depiction of gender roles in Princess Knight is quite revolutionary compared to Snow White (Sapphire rarely needs rescuing, she can handle herself, thank you very much... except when she does end up as a damsel in distress), it is still too constrained by its time and its author's biases.
The other thing that weakens this work is that the plot is all over the place. There is a prince, a princess, a witch with a daughter named Hecate, cherubs, the goddess Venus, Satan, pirates, executioners, scheming courtiers, mischievous nobility... in just two volumes! I also was not fond of the overly incompetent villains. Ah, if only the story had focused on Hecate, as she did not seem to need a boy heart to be strong and interesting.
