Rui Kanoya

The protagonist of the mecha anime Infinite Divine Machine Mono Magia. Rui pilots the giant robot "Gigas Machina," and first comes to his creator's house along with it after arriving in the real world. A child soldier in his world, Rui was constantly thrust into battle, having never had the chance to enjoy life or even go out on a date. He is thus relieved that the real world is much more peaceful. He is also attracted to girls younger than him.
