Only appears in the 2012 anime, Ghutatan comes to Earth from the planet Ghatanothoa for Mahiro to take care of her as if he were babysitting her. She is kind of childish for an alien, as seen in episode 11 when the Nyarlathotepian trio chases Mahiro for her. She has a butler named Roy Fooger the Lloigor. It was revealed that in episode 12 that Lloigor has been using Mahiro so he can bring all of Earth's adult games into space, as Ghutatan has completed her purpose on Earth. After Lloigor is destroyed, Mahiro and the Nyarlathotepian trio wish Ghutatan goodbye as she departs for Ghatanothoa.
