1000 Years ago, the youkais of earth gathered under tha banner of the youkai sages to wage a war against the lunarians, beings that live on the moon.It was the first large scale war to attack the moon as well as the last, the youkai army were annilated by the far superior lunar technology, magic and power. After the war, consipiracies rised that questioned whether the sages planned the defeat to uproot all who may oppose them in the future, but that's story for another time.
Fast forward 1000 years, youkai sage Yukari now wants to steal some things from the lunarians, and with that we began the far less serious second lunar war.

Story - 9
Despite saying far less serious, it still have quite a bit of story behind it, Yukari's motive is not simple and the act of stealing from the lunarians served a purpose in her centuries of planning. And despite only stealing a bottle of sake, it was a great achievement, since it is the lunarian's stuff. The story further expands on Touhou verses lore, such as explaining how lunarian space travel works and leaves a lot to think about

Character - 9
The lunarian society is introduced, as a race that have lifespan measured in thousands of years have technology (quantum cleaning fan) and magic surpassing everyone else. They can get quite up their own asses due to their superiority complex and arrogance, but none can deny they do have the ability to back it up. Two main lunarian introduced is Yorihime, the one in charge of lunar defense, and her elder sister Toyohime. Despite not much screen time, they manage to show quite a bit of personality, with Yorihime being a strict women with honor and treats everything highly serious, while Toyohime is the smarter one pretending to be the ditz (or maybe she really is one).
Other main characters include the scarlet devil mansion people, Eirin, Reimu, Marisa and Yukari. Reimu surprisingly became one of the few human to get invited into the lunarian city, both due to her power and probably because her attitude is similar to lunarian. Eirin and Yukari continues their complex plot around the relationship between the moon and earth.

Overall - 8
Highly amusing and leaves a lot for one to think about after viewing, a good Touhou manga. Now all that's left is for hifuu club activity to show the first lunar war.
