Ephraim  is voiced by Greg Chun.

Ephraim is revered by his comrades as a brave leader, as well as someone who is renowned for his battle prowess, gift for strategy, and unwavering determination. He is shown to have a very straight-to-the-point attitude, and dislikes wasting time on anything that strays from whatever goal is at hand. He even explains to Eirika that he also has a calling to battle, and it is something he is not sure he can control. One of Ephraim's dreams included becoming a mercenary in order to travel the world. But, Ephraim also puts his responsibility and kingdom first despite this longing for battle, which means he was never able to achieve this dream of his even after the end of the game.
