I'm guessing mostly teen and young adult male voices. You can use anything on the male characters' profiles for the recording lines, even if they aren't dialogue. Just read them as though it's the character talking about himself. Two examples:

You could also do what I did for my demo reel: If you keep the files that you recorded for auditions for various projects, you can just put those together into a demo reel. One time for one of my earlier demo reels, I just recited "The Jabberwocky" from "Alice in Wonderland" and did each stanza in a different character voice. Just whatever works to showcase the kinds of voices you can do. Or, since this is somewhat anime-esque, use quotes from various anime shows/characters.
