Question:

Anime and Manga? I am looking for some clean, kid friendly graphic novels for middle school and high school?

I work in a school and want some good graphic novels that are clean with no nudity etc to stock in my school library. Content wise it is very important so we don't have any problems.
Perferably fantasy or sci fi.
Can anyone give me some good ideas?
