Alfonse is voiced by Ray Chase.

Alfonse is a kind and serious man who is eager to maintain peace. He finds it hard to trust people, especially heroes and the summoner. This is because of Zacharias, a hero he was close with, “dying” in battle. Another hero Alfonse had bonded with had left to go home, with also played a part in his distant nature. Alfonse thinks of himself as not being the “prince” type, and joined the Order of Heroes even when Askrian people said it wasn’t royal-like and his father expressed outrage.
