I really enjoyed it. It was a fun, short read.
The plot itself is quite simple, the protagonist is on team A and infiltrates and spies on team B, trying to conceal his true identity. Even though the plot is simple, it has many moments where it got me like "Oooh, shit!", making me excited to turn the page to see what happened.
As being written and illustrated by Akira Hiramoto (Prison School), it has his signature erotic art and situations (LOTS of pantie shots, tiddies, tight outfits, etc.). Besides from the erotism, the art itself is beautiful, i simply love the way Akira draws faces and expressions.
The characters were a joy to read. They're fun, with interesting personalities which I'll definitely miss. That fuckass senpai is an example lol. My favorite being that crazy bitch Ooshima! One thing that annoyed me though, is that it seems the author forgot about certain characters, what happened to Mihono for example?
The ending suffers from the Author's decade old curse: rushed, unfulfilling endings. It's as if the tries to pack the entire ending in a single chapter and it simply doesn't work. I feel like if he extended the ending to one or two more chapters it would have been perfect.
Alas, it was good. I can see myself reading it again in the future.
Also, if you're planning to read this manga, get comfortable seeing balls all over your face.
