The reason I have this Hana to Akuma a 10 is because not many shoujos ever venture out to capture your heart. At the beginning, you may already be reluctant to keep on going because the manga starts out as the stereotype of a "typical shoujo manga." Hana to Akuma is about a demon (if you like vampires, well, this demon drinks blood) who picks up a human girl left in the cold and in the beginning, Vivi gives off the pretense that as soon as she gives him any trouble, she'll be disposed of.
Hana, the girl, is one of those brightening girls with a brilliant happy smile that people describe as a blossoming flower.


[A flower touched by a demon will wither and crumble.]


"A flower touched by a demon will crumble."


"If I touch Hana, she will crumble and wither, too."


These are the feelings of Vivi. If he touches her, he's afraid it will hurt that precious smile of hers.


I understand why you may not like this story. I mean, afterall, a 14 year old human girl and a 200 year-old demon? And Hana looks like a kid and a dwarf next to Vivi. Ah, but (SPOILER) (SPOILER) (SPOILER),
don't worry. Throughout the 58 chapters available, there is a potion that Hana sometimes digests for occasions in the demon world in which the potion makes her grown up. Also, the last few chapters are when Hana has grown up into a 17 year old girl, and she's no longer the baby she used to be. :) This story is amazingly funny yet tinged with sadness of the impossibility of the love and will keep you laughing, but as the end of the story nears, you will feel a pain as there are less and less chapters and less chapters until the end.
