I like the concept, but it was ruined by the main cast.
Japs are unstoppable in their pursuit of a perfect beta MC. The dude is so beta he can't even refuse his mistress' commands. Now he don't even has a dick, so he can stay virgin forever.
Another downside is the loli commander. Her design is lame, it was way easier for me to accept Testarossa in FMP, because she wasn't looking like a clown and she was always supervised.
The art is good, can't say the same about the story of the source novel.
