Nao Komatsu

As the eldest sibling in the Komatsu family, she is the first daughter of Natsuko and Goro. Alongside her younger sisters, Nami and Nana, she shares a close-knit family bond that remains strong despite her independence. Although she has moved out to establish her own life away from the family residence, she maintains a frequent and meaningful connection to her roots through regular visits to her parents' home.
