Kankyou Check Robo

An energetic robot that seeks to monitor and protect the Earth's environment. It found its way to the Gingarou Hotel after detecting a drastic change in the environment of the surrounding area.

Originally one of many Environment Checker Robots left stationed across the Earth when the remnants of humanity fled the planet a century ago, it has gradually lost contact with all of the other Environment Checkers and now believes itself to be the last surviving robot of its kind. It was designed to continue monitoring the planet's environment to determine whether it was suitable for human habitation, regularly transmitting reports out into space.
