Kei Tomigai

A friend of Kyo and Ryoko's; he willingly participates in most of Ryoko's film projects. Like Hayase, he appeared to be in the process of "awakening" and becomes aware of the true nature of Maihama, but fails to become a Celebrant before the Maihama server is reset. When Sin and Abyss invade the Maihama server, he reawakens to the degree where he is able to help Shizuno stop the Deutera areas from engulfing the Earth with Minato, Irie, and Kuroshio.
