The MC is basically a spin on either Mao or Stalin, considering the emphasis on China, its probably Mao. He is leading the poor supressed peasants against the rich monarchies and getting called a monster or demon for responding to the violence commited by the ruling class with the only tool he has at his disposal: violence. I suppose the stance Himiko's son (Three Legged Crow's main Angel) takes is actually one often brought up by western liberals, so i'm giving it +1 for cracking down on idealist fantasies. This work is obviously biased, but it usually gives reasons when refuting idealist misconceptions and plain lies. Is this propaganda? Definitely not. The connections to real worl individuals and events are too faint. Is this apolitical? No, but you'd have a hard time and a terrible result if you tried to make a Sci-fi work without politics. It proposes a set of morals and ethics usually rejected by western intellectuals for being barbaric or cruel, while inaction is actually much more cruel.
TL;DR: Don't believe everything media and politicians say, kids. Don't be like Himiko's son.
