Riko Saibara

A psychic girl who Mamoru partners up with. Despite having a fearsome set of powers and being quite skilled at using psychokinesis, she's very ditzy. Following their initial meeting, she quickly falls in love with Mamoru, often rambling about her dreamy ideas for how their relationship will look like.

Due to her father being a psychic and her mother not being one, she only has one Ring Eye, which she usually hides under an eyepatch.
