I must say that I don't usually review anything but this Mahnwa had no reviews so I decided to give it a shot.
The animal kingdom seems enranged by the behavior of humans; their contamination, bullying, betrayal, this work has it all. The king decides to send the princess Yegrinna to the world of humans using a magical portal. In the human world she meets a guy who loves math to the point of becoming erotically exited by it and changes his life in unimaginable ways.. There are ecchi moments,funny ones and fight scenes well you do the math cos(x)^4 *nosebleed* xD
Art: Wow! Is
beautiful, maybe is just me but I really liked the art. Similar to Persona 4.
I've only read 3 volumes. I may come back later to change my opinion otherwise I'd recommend it.
