Got mixed feelings about this. The artwork is superb, but the story is too underdeveloped and the characters actions and personalities are too thin. For the manga to hit the top-notch it would've needed more thoroughly explaining and more sincere and in-depth characters.
The 3 stars goes for Samamiya-sama's art and the cute cats. I'm not cat-biased. At all.
