This is my favorite manga series of all time. It's still going, and basically it's about this little boy who is a mage, and he's surrounded by all these school girls, and most of them are trying to perv on him even though he's only 10 and they're all like, 15. There's always either something extremely funny going on, or something extremely exciting. It's almost never sad...though there have been moments. It's super cute, and I urge anyone who has not already read it to read it. You will not regret it.
F.Y.I: Those of you with a shota-complex...or those of you who have a weirdo schoolgirl-complex, you gotta read this.
