Relationships
Honoka Maki

Due to the death of Maki's friend Ruru, which Maki blames herself for, she had distanced herself from anybody, refusing to be friends with Nico who had asked her to be her friend. However, the Kiznaivers had found out about Ruru, helping her to find out about the true message Ruru wanted to give to Maki, giving her strength to make friends. Maki would be closest to Nico, since she was the first to approach her as a friend.

Hajime Tenga

Her attraction for Tenga could be seen sometimes from episode 7 and 8. However, she had confessed she liked Tenga in episode 9, when Chidori was jealous and hurt when Katsuhira hugged Noriko, causing Tenga to be angry at Katsuhira. She had revealed her inner voice then, which could be heard by all Kiznaivers, saying if Chidori didn't want Tenga, Chidori should give him to her. Later, Chidori, Tenga, Hisomu, and Nico were supposed to meet at the mall but while Chidori and Tenga have their little exchange, she texts them to start shopping without them. She and Hisomu talk about the situation and Nico wants Chidori and Tenga to not be stuck in an awkward stage and all be friends even though she isn't giving up on Tenga. She also mentions having a playful fist fight against Chidori at the for Tenga's love to make them all closer. In the end after she discovers Chidori is slowly starting to develop feelings towards Tenga, out of jealousy, she tells to Yoshiharu Hisomu that she still loves Tenga and will not lose him to Chidori.

Noriko Sonozaki

Among the rest of the Kiznaivers, Nico disapproves of Noriko and Nico is indifferent to Noriko. Nico makes it clear to the Kiznaivers that she honestly doesn't care for Noriko, no matter how tragic is. In the end of the last episode, Nico tries her best to be friendly towards Noriko, as Nico generally wants to be nice and sociable with people.
