Anyway i'm reading 5 mangas at the mo.
Battle Vixens (Ikki Tousen) - This is about a group of people who are destiend to fight for ever due to spirits sealed inside there Ear rings. This gives them imence power. Well worth a read or a look at the anime if you can get past the Fan servis
Koe de Oshigoto - About a young 16 year old girl who is asked by her sister to help out at work but it turns out she wants her to work as Hentai voice actor. This is herlarious and the sexual humor his really funny.
Battle Royal - This one is famous. A class is put on an Island and told to fight to the death and kill everyone else in order to leave the island. This is really good but not a bed time book. I highly recomend this one.
Bleach - Again a very famous one and again very good and funny (Chad is awsume!!!!). I recomed reading it or watching the Anime atleast.
My Balls - I'm kind os ashamed i read this but it's really funny. I won't explain this one as it's 1 step away from being X rated so you will have to do research on this one.
You can read all of them at
www.mangafox.com (I think)
