Nagamine Nozomi

Nozomi is a childhood friend of Nozomu, whom he grew up together with. They grew close when Nozomi's family started taking care of Nozomu when his parents went missing. Nozomi tend to be very kind and reserved, but when the matter concerns Nozomu, she will be very hostile to anyone who gets too close to him.

Nozomi clashes with Satsuki over Nozomu often, and considers her a rival, albeit unilaterally.
