This is horrible. I don't have the first clue how this manga has 4 stars. The art is like the notebook-paper doodling of a moderately dedicated high-schooler: not hopelessly incompetent, but fundamentally defective in proportion, consistency, and expressiveness.
The plotting and characterization, though, are hopelessly incompetent. This series isn't worth the effort to explain how bad it is. If you doubt me, just read the first chapter on a scanlation site. Heck, just read the first fifteen pages. You'll see what I mean.
