Hana Kimi, Hana Yori Dango, Ouran High School Host Club, Kare First love, Fruits Basket, and Dengeki Daisy :D
I would suggest Ouron High School Host Club or OHSHC. It may seem weird and gay at first, but it is incredibly funny atop romance.
Some mangas similar to "Love in the Mask" include "Cheese in the Trap" for its focus on romance and school life, "Orange Marmalade" for its blend of romance and fantasy elements, and "Bride of the Water God" for its forbidden love themes and intricate plot.
One is Karin, which is also known as, Chibi Vampire.
Try Kaichou WA maid sama! its really funny n romantic n has a demon! :)
Hellsing is by far the best manga/anime in my opinion. If you like vampires, zombies, huge guns, and Nazis, then is is the book for you.
There are many mangas, it really depends on what you like, be it action, romance, horror ect. Some of the big and popular mangas out are:NarutoBleachOne PieceDeath NoteSome Legendary mangas are:Astro BoySailor MoonDragon BallsDoremonIuyashaSome mangas that I recommend:Vampire KnightFruits BasketKoizoraGirl Got GameOuran High School Host ClubHana KimiHana Yaio DangoKimi Ni TodokeHigh School DebutLove MonsterPeach GirlNote: most of the ones I have recommended are romances but are still very good.Also if you wish to read manga online some good websites areMangafoxReadmangaOne Manga

probably not. the mangakaabandoned this manga cause it wasn't that profitable and wrote some other mangas. some of them yaoi mangas by the way...
