I decided to read this because I loved the anime...
... but honestly, this was a disappointment. I saw the amount of chapters translated and figured surely the story had to be ahead of the anime here. NOPE. It is just long, drawn out, repetitive, and packed with filler. The manga art style seems out of place, and constantly shifts between normal mode, shoujo-mode and cartoony animals mode. It has a tendency to give long, drawn out explanations of every little thing repeated over and over again with slightly different wording... but still describing the same damned events.
It doesn't have anything like the tension that the anime had. Most of the conflict with Being X is absent. The action scenes are awkwardly drawn so it is tough to know what is even going on. The supposedly comedic misunderstandings are repeated often enough to an absolutely stupid extent... to the point where it seems the entire plot now hinges on them. You could count the number of times anyone in a conversation with Tanya did NOT misunderstand her on one fucking hand.
While it isn't "bad", and maybe my expectations were too high, this was still a let-down..... at least compared to the plainly superior anime.
