Emile Crossfode

Hayato's roommate.

Her name which she told to Hayato 10 years ago is Emilia Hermit. Later it's revealed that her name is Emilia Gudenburg and is the princess of Gudenburg royal family.

She was once saved by Hayato during an attack, but due to the circumstances of the attack, he doesn't remember her.

Rare survivor of an attack and subsequent virus has made her one of maybe 10 people with advance compatability with the Hundred.
