NDK is really great. It's a small con, which makes it a seem a lot more open and welcoming to new fans. It's sort of lost it's 'anime only' standards, too, which makes for a lot of fandoms being represented. I certainly enjoy it.

The quest got started last year, but it only had a few people. This year, you first talked to a guy with a blue question mark. He gave you a mission, of finding Gemna Seuss. After you found him, he gave you a mission to find one of two people. When you found them, you had to give them pocky, then they gave you a new clue. So, it was mostly just looking for NPCs, and finding things for them. It was really great.
