Just guessing the names based on the art style so don't hesitate to correct me if I'm wrong.

I think Kouki is the artist of D.Gray-Man... and...
..Why do I NOT know his name..
Anyway, the author of Yu Yu Hakusho.
The others I know, and are correct. Except Hikari.
...No, that's Evangelic style?

Never knew kubo's style would be this perfect to lyra

This artist is genious! Awesome style parody. And he even doesn't realize that there is a "pokemon 1000 users tag"...
