If you're like us, morning grogginess has a tendency to sneak up on you, but you can't spell vigilante without viglilant (we checked), and it's not gonna be easy changing the world from the inside of a jail cell. Keep your head on a swivel with a little help from caffeine and the anime experts at ABYstyle. With a design that changes when heated to reveal L lurking behind Light and the rules of the Death Note, it's the perfect gift for fans of the series.
