As their name would imply, The Ninja Clan is a large group of Ninjas. They are the 13th enemy added to the game. They guard important areas in Hiroto Dojo from nosey intruders like Joe.
While exploring Hiroto Dojo, Joe may encounter several sections of the building barricaded by laser trip wires. If Joe passes through the lasers they will begin to flash. If Joe passes through another laser trip wire that is the same color as the one previously activated, he will be ambushed by a corresponding squad of Ninjas, who will proceed to strip and attempt to sexually exhaust Joe. The Lasers do not pass through opaque objects such as walls, ceilings, floors, crates, or umbrellas.
The following is a list of the current squads and their corresponding color.
All of the ninjas dress as the stereotypical shinobi shōzoku (ninja clad in black garb), each of them wearing black and loose fitting clothing with a navy blue forehead protector around their head or necks. The headbands have a metal plate on them with an engraving that resembles a tree or a leaf.
The Ninja Clan primarily guard the vault on the far right side of Hiroto Dojo, preventing anyone from reaching the vault or leaving once the have seen it. They also guard some of the interior portions of the pagoda.
