Remi is usually depicted as a rather childish girl who has a very straightforward personality and who wears her emotions on her sleeve. She seems to rely on other people's help regularly. She's also not very smart, often compared to Izumi Miyamura about which one is more of an idiot.

Remi has a slightly child-like, high-pitched voice that often has an aloof tone, but sometimes shows a great deal of cunning.
