He doesn't technically "control" paper in the way one might expect, like folding it into shapes or making it fly. Instead, Light uses Shinigami Eyes, given to him by the Death Note, to write people's names in the notebook, which then causes them to die.
He uses paper as a medium for his powers, which is arguably a form of control over the physical form of paper itself.
Here are some other characters who might be considered to have some degree of control over paper:
* Shikamaru Nara from Naruto: He uses his Shadow Possession Jutsu, which allows him to manipulate shadows, and can sometimes use them to manipulate things like paper.
* Paper from Paperman: This character isn't technically an "anime" character, but he's from a Disney short film and has powers of paper manipulation.
If you're looking for characters who control paper in a more literal sense, you might have to delve into some lesser-known anime or manga.
