one of the biggest pieces of dog shit Japan has ever created. Japanese imperial propaganda in modern times and the weebs who like this are the biggest reason for the decline of the West. There is nothing worse for an artistic work than to serve solely as propaganda for a long-lost revanchist cause. The story is simply built so that the Japanese win all their fights like a child playing with their action figures without the depth and reflection that a story like this (that of altering the past so that your side wins) needs. Historical figures are unidimensionally bad if they are against Japan and unidimensionally good ifthey are for Japan.
simply war propaganda made into series (in peacetime)
Practically, this series is a worse Zipang and Silent Service, a total waste of time and an insult to the animation.

Although if you are a supporter of Japanese imperialism you already have your favorite series.
