Aran Kokubu

Aran Kokubu is Tsubasa Misumida's great-grandfather, a man whose life is deeply intertwined with the land of Nagaoka City. Throughout the story, he serves as a quiet but powerful voice of reason, observing with clear eyes how modern society blindly conforms to unspoken social pressures—what the narrative calls "the air." Rather than being swept up in the noise of public opinion, Aran stands firm, offering Tsubasa the kind of grounded wisdom that only a lifetime of experience can provide. He is both a spiritual anchor for his great-grandchild and a living embodiment of the values and memories tied to their ancestral home.
