Rem

Rem (レム) is one of the twin maids working for Roswaal L Mathers.

Appearance
Rem has medium length sky blue hair that covers her right eye, large light blue eyes, and young features. She also has hair clips towards left side of her hair, flower-shaped ribbon on the same side of her hair, and a maid hairband. She looks nearly identical to her sister apart from her hair, eyes, and ribbon coloring. She usually wears a maid uniform, and since her chest is slightly larger than her sister's, she secretly changes the measurements to hide it.

Personality
Rem tends to speak in a superficially polite manner and sometimes acts without thinking. She holds both respect to the point of worship and guilt toward her sister for an incident in the past.

Because of her respect and guilt toward her sister, she used to think of herself as inferior. After Subaru saves her, she falls deeply in love with him, becoming one of his most loyal followers. Rem will stick with him no matter what happens, even if Subaru rejects himself.

Currently Rem has had her name and memories eaten by Ley Batenkaitos, erasing her existence from the world and putting her in suspended animation.
