Personality

Ethan is a selfless and friendly person with strong sense of justice. He can be cheerful time to time and even somewhat mischievous, though at the same time he can be more pragmatic and somewhat somber.

Due to representing the good side of Joker Undead as the Navy Joker, while he does possess feral and berserker-like nature like most Undeads, he only shows this when he is angered or those who he cares about are threatened or insulted in any manner.

His relationship with Sakura plays a crucial role in retaining his sanity and humanity, where his love for her vows him to save her from such pain and cruelty she endured from the Matous and becoming the Black Grail.
