Murao Mima

Considered by Key as her creator and grandfather, this character has a complex relationship with his creator. A pioneer in robotics, his groundbreaking work was significantly advanced after meeting Tomiko and Geist in Mamio Valley. He utilized a supernatural substance derived from Toyoko to power his creations. In a move to protect his daughter, he suppressed all supernatural abilities in Tokiko, which unfortunately also impacted her human consciousness, leading Key to believe she was another automaton.
