Nitta Arata is a typical 21 year-old junior attending college of science and engineering at Toaru University. He is bright, he's in the engineering program after all, but he definitely is from a working class background. He has been working his way through college for the past 3 years without major incident, so being swept up in a warped experiment of an equally warped professor was the last thing he expected in the second half of his college days.
