時尾 保

Ethan's uncle, Timothy's younger brother. A freelance writer engaged in chasing the long-ago incident. He's brusque, and has a serious disposition. Although it seems he did not get along well with his older brother, he took Ethan in after Timothy and Pamela disappeared. He was the original founder of the Chronos café.
