Suzie loves attention, so of course when someone suggests she join them at a convention she studies up to find something she is suited for and still is popular.
This was a YCH from rachverity and being a fan of SOA I had to get it, the problem being that I had no characters that fit Asuna except Suzie, though Tia or my wife's character (who is also a huge fan of SOA) would have been better suited.
