Nozomi is a typical girl whose goal is to become a "super charisma influencer" and conquer the world with the power of social media. In contrast to her "public" villainous persona, her actual personality is honest and innocent.
Nozomi's overall personality resembles Nagao Kei's, with Kenmochi Toya's talkativeness blended in; she is cheerful and often laughs during streams, including at her own jokes. She likes to jokes around her fans, and it has since been regarded as the major trait of her personality. She also has a fondness for internet memes and often uses it to banter with her fans.
When a stream is starting she greets with "Welcome to Underground," and when ending a stream she says farewell with "La Jodasoh Steana". Due to their lengths, her fans unofficially abbreviated them as "WtU" and "La!" respectively, both of which became official as of the opening of channel membership, adding them as two of its custom emotes.
