Sensei is a mysterious martial arts teacher in CP3D.
He was first sighted during Dig Out The Dojo, where he was helping to dig the Dojo out of snow after it was struck by lightning. Since then, he can be visited in the Dojo, where he can be challenged in a Card-Jitsu duel. Defeating him will grant you access to the Ninja Hideout.
