Koori No Mamono No Monogatari
This is definitely on the top of my list of best mangas. The story was so touching and at times it really brought me close to tears with the earnest and purity of love. I loved all of the characters, the character development and the story. It had great meaning; darkness is in everyone, and although it is not a physical form, if you learn to accept it and learn from it then it is ok. Great, cute, lovable story! A must read, and a re-read at that! I hope I will come across another one as cool, sweet and epic as this!
Hanatsukihime
Siva, a devil makes a contract to give his heart to a child, Lys, for 16 years. Upon the 16th birthday, he will take his heart back. The story is cute and sad, I teared up at a few of the scenes, such as Malouf and Fatima and their fate. Siva is really hot! I love hot bad boys haha. It was a cute story, and I enjoyed it!
Konya mo Nemurenai
Endo being tall as an adult and a demon is totally sexy! He's not quite manly in his small human form lol...not to mention his "kid's dick" lol. It was a cute story, but I really wanted to see a more intense and developed relationship between Endo and Hiriki. The entire time Endo read Hiriki's thoughts, how embarrassing lol. Look out for sequel that's not yet complete: Kimi To Kore Kara
