Interesting take on Rumia's backstory. Clashes a bit with Reimu's way of killing anything that becomes a youkai as well, since village humans aren't allowed to.
There's some subtext here and there it feels like, could be the yuri goggles. Zuikaku always talks about shoukaku as do others about sister ships or who've they've met before as the above stated.
Well, I said I’d wait on my judgement/opinion earlier so here it is:
Ok... this manga probably won’t be licensed and sold in bookstores, in my opinion. It’s funny, yet the artwork doesn’t shine like others have managed to get published through amazon.
There’s enough interest for it to be sold through electronic media.
