While making this review, I was trying to keep it as short as possible, keep this in mind. I personally prefer short reviews, with as few spoilers as possible. If you have any questions, please go ahead and ask or Google your question.
Aono Tsukune is an average boy who failed his High School entrance exams. Tsukune's parents went to the ends of the earth to find a high school that would accept him. Tsukune was enrolled at Youkai Academy, an academy for the education of monsters. Tsukune was unaware of the details of his new school (as well as his parents) when he met Akashiya Moka, a vampire. Tsukune soon learns that Youkai Academy is a secret academy not meant to be found by humans and any human found on the grounds must be executed. He now has to pass his classes, avoid revealing his true form, and avoid being killed by the many dangerous monsters in the school.
Let me start right of with saying: This is my number one, absolute favourite manga. I absolutely love it and whatever errors it may have, I can personally not see them. So please do forgive me, if I miss anything major.
Many reviews and ratings are very bad, when it comes to this manga. Most of the ratings rate badly, solely because of the Ecchi parts you will see. Personally I find them a good way to add to the comedy, and it's always good with some eye-candy. Of course opinions on that may differ.
What surprises many about this manga is the story. The story starts of decently and keep escalating from there. If you allow the story to get a grip, it will hold so tight, that you will fall in love with the manga.
If this manga even appeals to you a little bit, I'm sure you'll agree with me on the overall 10/10.
