Ken is a yellow cockatiel who can speak in heavy kansai-ben dialect. He accompanies either Lilith or an unnamed main character on their travels. Despite being loud, obnoxious, lecherous, perverted, overly confident and slow to avoid trouble, he often ends up getting punched, squashed, beaten, or otherwise harmed due to tasks assigned by his companions or because of his big mouth and inappropriate behavior. In the game, Ken's true form is a kendappa working for Arya.
