Your Rating for the Artwork: A
Your Opinion/Review of the Art: I personally like the style of the manga, the character artwork is great with each one having a unique look, but that aside it is clear we are viewing the work of a talented manga-ka; someone that can really draw. It is very detailed and there are lots of nice little details and touches in every panel.
