Klavier Gavin

Klavier Gavin is the main prosecutor in Apollo Justice: Ace Attorney as well as the lead vocalist and guitarist of his own rock band, the Gavineers. Unlike those before him, Klavier is actually quite honest and friendly, even when he is first introduced. He is the younger brother of Apollo's mentor, Kristoph Gavin.

Name
"Klavier" means "keyboard" or "piano" in German, but Klavier Gavin plays neither of these instruments in his band.

Background
Klavier trained to become a prosecutor in Germany (the same place where a certain whip-wielding prosecutor was trained).

His first case was seven years ago, the same case that cost Phoenix Wright his attorney's badge.
