A character with a very bright personality who supports Guest. She is not human, but a virtual entity—a holographic navigator known as a Holo-Actor. She functions as a navigator for multiple G-Divers simultaneously. Since a single AI shares the thoughts of all Sthesia Awares, the experiences and actions of every Sthesia in the world influence her. As a navigator with multiple instances, her outfit can be changed according to the G-Diver's preference. Ex uses a mature-looking Sthesia with glasses, while Pinya uses a student-like Sthesia. According to Sthesia, Guest's Sthesia is the most 'normal' one. One wonders what the other G-Divers' tastes are like... Sthesia revealed that Jupiter Ten, where Guest worked for human evolution, had long since ceased operation, Earth was already destroyed, and she had entered cold sleep to act as a Holo-Actor for her own evolution. Guest, who loves Sthesia, was actually happy to hear this, saying they were glad to be working for Sthesia's sake instead. She has long white hair, blue eyes, and a relatively ample bust.

He once interfered with the GA data of the Battle of A Baoa Qu at the end of the One Year War in the "Universal Century," distorting history. Unit: Extreme Gundam.
