I read a lot, and also forget a lot. I prefer comedy and slice-of-life mangas ^^
Neko Musume Michikusa Nikki: Daily life with a neko girl and her monster friends
Gon: The true power of a small dinasour against Earth's nature. Speechless manga
Aqua/Aria: Slice of life about Undines, a gondola-rowing tour guide on a flooded Mars
D-Frag: Very silly but comedy manga
Gokicha: a tiny roach girl who wants to be friend with human
Hibiki's magic: A light-hearted manga with touching moments
My name is Zushio!: Read it, and laugh (there is a fox girl inside for someone interests)
To name a few
