Reviews: Neon Genesis Self Insertion
You'll laugh your butt off, and then you'll get to thinking about how the characters' lives and interactions with each other have been influenced (or not) by what they have to do in the fics...and that line should be interpreted in every conceivable way. Highly recommended.
Manages tons of hilarious references to other series, and written very well. Not finished yet, the author is updating slowly but surely.
