|First appearance||Day 1|
Emi is Lock's younger sister.
Emi was created by Jacob in an attempt to recreate what Agonius had done to create Lock. She, like Lock, is a near perfect Clockwork. Unlike her brother, however, she lacks a human soul, something Lock gained from Agonius.
She grew up with her brother in a seaside fishing village and both of them were unaware of her or Lock's true nature. She and Lock were taken in by Jacob, who took the name Tobias and raised them as if he was their father, although claiming to be their grandfather and said that their parents died in the war.
