Nozomi enjoys helping out at the local Kanda Shrine. Nozomi and Eli Ayase are close friends, and she has admitted to Honoka Kosaka that she has seen Eli's emotional side.

Nozomi is also the person behind the name of μ's. She decided it because she knew the nine girls would eventually come together. The Muses are also what the nine Greek goddesses and daughters of Zeus are known as, therefore, Nozomi suggested the name μ's.
