Hello, it's me again!

I just finished watching Kite Liberator, a movie about a young high school girl who's actually an assassin under her shy and innocent mask. I won't be long, I'm looking for a manga that follows this story line, though the girl doesn't have to be shy/go unnoticed at school. Actually, the more popular she is, the better, but it doesn't have to be that way.

Thank you!

To some extent, I think the Full Metal Panic series all fall into this category. Though it primarily centers around the male of course. Maybe a little less about him having a secret identity and just him not fitting in at school.

I have not seen all of it, but from what I did see, the anime Blood C follow this almost exactly. Only instead of being an assassin, she hunts vampires.

Lastly, the manga Young Gun Carnaval fits this almost perfectly. Its not a great manga though, and feels very axed. You can tell there's a lot more planned than it even touches on with the characters that are introduced. It also tends to ramble about politics between governments and gangs.

assasin huh? and a popular student to boot. try Aлёша!. hope it helps.

Resistance is amusing...

Gakuen police mc is a agent for the police force who is going undercover.

Arachnid?

Okay, so I thought I wouldn't be able to find the title of the manga, but by coincidence it was in another forums post in the I'm Looking For section! 9 Banme no Musashi The girl is not always in school, but there is a rather long arc where she is.
Also, although it's not about an agent or spy, P.A. may interest you.

I rate manga with 5 being the average score.

Not a manga (I wish) but I would highly recommend Noir. http://en.wikipedia.org/wiki/Noir_(anime)Here's a trailor for it..http://www.youtube.com/watch?v=-CKu4uUMLl4 I prefer it subbed though..
The main character wakes up and doesn't remember her past. Throughout the series she is searching for who she is while a group is targeting her.

Gunslinger Girl also fits. However it is really sad and the girls aren't assassins because they chose it.
