Yuuto's former name, "Izaiya," might have originally been "Isaiah." I mean, he was Christian, and the Japanese way of saying Isaiah is "イザヤ," Izaya. The Bible the Japanese "read" from (because how many Japanese are Christian?) is translated from German, so it explains why it doesn't have the same pronounciation as in English. And light novel authors have been known to mess up when it comes to foreign names.
