Height: 180 cm.
Age: 13

Rui is an out going genius who likes to create inventions most of his free time, inventing various things like robots, drones, etc. He lives by his own set of rules, which causes many of his classmates to consider him a weirdo and isolating him from them. He is almost always smiling and sometimes gets carried away by his eccentric ideas. He often hangs out on the rooftop alone to work on his inventions. He's lonely but he doesn't mind.
