If I could have given this series a higher score than just 10, I would've. I have never written a review on any series before, but Hana to Akuma really impressed me!
I don't think my English is good enough in order for me to fully express just how fantastic I find this manga, which is such a shame, but I will try my best anyway!

What I love the most about Hana to Akuma is the way Vivi's so, so delicate and sweet love for Hana is presented. All his actions revolve around her and yet he dares not touch her in fear of tainting her purity. She's the only one he wants to protect, but he also sees himself as a great danger to her. Vivi never planned to get attached to Hana, but somehow it ended up happening and the way he keeps questioning himself and the way he keeps wanting Hana and then pushing her away show us just how confused he is. As for Hana, I was really pleased to witness her development! She slowly becomes more conscious of all these new emotions in her as she grows, and for every obstacles she has to overcome, she becomes more aware of things like responsibility, consideration and fear - which also becomes one of the reasons why she's reluctant to express her real feelings to Vivi. I don't want to reveal too much, so I'll just say, that the love between both main characters develops really naturally which I really like since lots of shoujo mangas tend to have those relationships that just happen too fast, thus making it impossible for me to actually understand it. But this love between Hana and Vivi really has depth. On the surface it seems fragile, as if it could just break any minute, but as the characters develop and I get further into the story, it soon becomes clear just how amazingly strong this love is. Their interaction with each other creates both super funny and sweet incidents but also hearbreakingly sad ones. I laughed, I squealed, I shed a tear or two and I cried my eyes out (well, I AM a little sentimental).

The artwork is absolutely stunning and very expressive, and the mangaka has really managed to show me every single character's feelings through her drawings. I really am amazed. Especially when the character is saying one thing but not meaning it - the "hidden" feelinga are then exposed anyway by the expression of the characters. Maybe I'm just blabbering now, but all in all I LOVE the art!

Since this is my first time doing a review I'm not exactly sure if I have done this right. Please do excuse my lack of order and everything seems to have just come out in one random flow (which it actually has xD).

But for now, this is what I had to say about Hana to Akuma. I bet I will someday read it once again, perceive everything differently and most likely edit this review ^_______^ But for now, I'm happy I got to write down my thoughts regarding this series!
