My favorite manga, without a doubt, has to be Sailor Moon. It´s so old now, but it´s a total classic!

I love Naoko Tekeuchi´s drawing style.
As far as more recent manga, I really like the manga called
Skip Beat! The main character is a girl who refuses to become depressed when her famous star boyfriend dumps her....instead she vows to get revenge and beat him in what he´s best at: showbiz!

It really makes you laugh and smile and go "awww".
I also recently started reading a manga called "
Subaru", which is about a girl who is fighting to become a ballerina after discovering a passion from dancing after dancing for her bother in hospital...the drawing style at times is not to my taste, but the story itself is so beautiful....
A manga I would totally recommend is
Please Save my Earth. It´s 21 volumes long, and the drawing style is quite plain, but the story is very very interesting. The plot revolves around a girl called Alice, and a series of people she meets....it turns out that most of them have some sort of "ESP-type" power....and though they don´t know it, it has a lot to do with their past lives....
@lolitagirl: Wow! I just started reading LIFE a week ago or so, it´s such a coincidence to read a post about it! I´ve only read volume one so far, but it´s certainly a gripping story. I have to read it in small doses.
@Zeruda: I also read Vampire game a while ago! It was a fun story, but I never finished it because it seemed so long.....and I think I only had a volume or two left to finish.....maybe I should go back and read it again, hahaha.
