Description: All right, I'm writing one of these myself right now, and they're great.
Basically, it's a piece that's written from any standpoint, meaning that 'she', 'you', or 'I' are acceptable for the original character. It contains characters from any anime, manga, or game that you know the characters from, though I'm limiting these to the ones that I know myself. You have to have at least one original character.
The original character(s) goes to a party with all of the people from the anime/manga/games you choose to include. It has to start as a formal party, but after that, just about anything goes.
Must include someone spiking the punch, one or more people getting seriously drunk as a result, two people who hate each other finding each other and starting a fight, someone hitting on someone else, someone getting covered in glitter, each of the original characters having a set escape route, and having one or more of those originals escaping at the end. It must be called "The Disaster Party".
NOTE: Characters that are not on the list but are from the game/anime/manga that you're including can be used.
