This second film in the series offers more of the same. It's a peculiar mix of elements that don't quite fit together, at the same time it's what gives this film its unique identity. If the idea of watching a band of underage girls solving big spy mysteries in an alternative take on Victorian England appeals to you, this is definitely the anime you should be watching.
A failed assassination attempt on the third prince has the kingdom in an uproar, but secret intelligence suggests this is merely a diversion to mask a bigger plot. Three experimental bombs have been stolen and word is that the bombs were smuggled into the kingdom. The girls will have to figure out who is behind these evil plans and what their end goal is.
The animation is pretty decent, and the slight steampunk elements are fun, but the style is a bit flat and too polished for my liking. The premise really makes no sense, but the films are properly paced and there's little time to get bored. It is far from the greatest anime I've seen, but it's easily digestible, distinct enough, and smart enough not to overstay its welcome.
