gag mangas are mangas with not much...seriusness...almost like superman... It has simple drawings with very simple stories. Almost close to American comics.
It depends on what you like to read. If you like mangas about young kids life, young romance and a comedy manga, then it's for you. If not, they probably not.
Mangas are Japanese The drawings are very beautiful the storylines are interesting often read right to left
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.
Science Fiction, Romance, Action, Fantasy, Horror, Mystery, Supernatural, Comedy, Drama, etc
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
Here are some mangas (besides Kitchen Princess) I read that have romance in them:Fruits BasketFlame of ReccaZodiac P.I.Rurouni Kenshin/Samurai XCardcaptor SakuraAngelic Layer (only a little)Full Moon wo SagashiteKaimikaze Kaito Jeanne andShugo Chara!Some of these mangas are not E rated, so chose wisely. :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.
Prince of Tennis!
There's Bloody Kiss. It's your choice whether it's good or not. there's Chi-bi vampire or Karin it is watchable in English and they are the same show but diff. titles.
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.
some good ecchi mangas are: velvet kiss nozoki ana love junkies hetakoi and more.....
