Nozomu Nanase enters as a 16-year-old male who matures to 24, with his height evolving from 172 cm at 16/17 to 176 cm by 19, then stabilizing at 179 cm from age 23. He sports burgundy hair and light burgundy-brown eyes. Initially, his hairstyle features face-obscuring bangs, later secured by a clip to differentiate him from Sora Ohara. Born November 9 with blood type O, he lost his father in childhood and was raised by his mother and older brother Izuru. Nozomu idolizes Izuru, aspiring to emulate his charismatic bassist skills after sneaking into Izuru’s high school graduation concert. He treasures a black lightning-bolt guitar pick from Izuru’s debut, attached to a strap as a lucky charm. Energetic, quirky, and playful, he relishes teasing friends—especially Ren Munakata, a high school classmate and frequent prank partner. He collaborates closely with Sora Ohara on schemes or spontaneous ideas, their dynamic including lighthearted disruption competitions. Both avoid pre-exam studying. Nozomu champions optimism, adopting "Stay optimistic" as a catchphrase. As SOARA’s bassist, he uses nicknames: "Sora-senpai" for Sora Ohara, "Mori-senpai" or "Morihito-senpai" for Morihito Arihara, and "So-senpai" or "Soshi-paisen" for Soshi Kagurazaka. Ren Munakata is addressed simply as "Ren." Others call him "Nozomu" or "Nozomu-kun." His habits include maintaining an extremely messy room and setting multiple ineffective alarms for waking. He participates in online gaming with characters like Koi, Ichiru, and Naosuke. Despite his vigor, Ren defeats him at arm-wrestling. Izuru remains saved as "Nii-chan" in his phone contacts.
