The story works as it is Saph. The problem I see is that it can't be used as a legal story because of all the copyright issues. I know that wasn't part of the rules or anything, but I think that an original story should not use other works to make itself better.
Heck, I voted for it because its good and fun... but making the character speak like Keima from TWGOK or act like Okabe from Stein's Gate, while funny, is plagiarism. Even the title takes advantage of the recent Evangelion movies.
