Attack on Titan

I love Attack on Titan. It is a cartoon that my dad and I watched on Netflix. It is from a manga book which I found at the library and read. The series has a guy in it named Levi that is a main character and really awesome but the protagonist is a teenager named Eren. There are figures of the characters as well. I found a Levi figure online that looked exactly like the character. There are more books than there are episodes of the cartoon. I can't wait for the other books to be made into anima.
