She joined the club as a first-year after basically being kidnapped into it, though she quickly became a fixture. Her most distinctive trait is how she ends sentences—always tacking on "desu" or "desu yo/ka," which has become pretty much her signature verbal tic.
Tamaki's known for two main things: an absolute obsession with cake and her camera. She's almost always got a camera on her, and she's genuinely talented at hiding it, which makes sense given how often she pulls it out to snap pictures.
