Naoya

Height: 182 cm

Possessing a mischievous, teasing personality, he is a renowned genius programmer—the very person who created the Demon Summoning Program.

He is the one who drew Kazuya and the others into the events of the story, prompting them to take action in order to uncover his true intentions.

As Kazuya’s cousin—and having lost his own parents at a young age—he lived with Kazuya until a few years ago, serving as a figure much like an older brother. At times, he displays a level of intimacy that suggests a bond closer than that of mere cousins.

He claims to be uncomfortable around "God," though—or is he?
