Yukito Kunisaki traverses Japan on a generations-old family quest spanning a thousand years: to find the mythical "Winged Maiden." He survives through street performances using a unique stringless puppetry technique, taught by his mother before her death. This skill provides his primary, albeit meager, income, often forcing him to focus solely on basic sustenance. Abandoned at a shrine in early childhood, monks primarily raised Yukito until his mother returned. She taught him houjutsu (a mystical art) and the legend of the Winged Maiden before her subsequent death, after which he continued the journey alone. His lineage traces back to ancestors Ryūya and Uraha, with strong implications he is Ryūya's reincarnation, evidenced by shared grey hair, golden eyes, and personality traits. Arriving in a coastal town planning a brief stay, Yukito meets Misuzu Kamio, who invites him home. He forges bonds with Misuzu and her aunt Haruko Kamio, prompting him to extend his visit. Taking odd jobs at a local clinic after the doctor observes his puppetry, he befriends Kano Kirishima and Minagi Tohno. Learning of their struggles—Kano's belief in magical powers from a wrist bandana and Minagi's emotional isolation and family issues—Yukito chooses to remain and support them. Yukito later discovers Misuzu suffers from a curse causing uncontrollable crying spells when forming emotional bonds, preventing lasting friendships. Believing his departure might ease her condition, he attempts to leave but quickly recognizes this as a mistake and returns to support her. This decision leads to the revelation that Misuzu is the reincarnation of the Winged Maiden he seeks. Their shared connection to a past life—where Misuzu embodies the cursed maiden Kanna and Yukito mirrors her guardian Ryūya—becomes clear. After Misuzu recounts a final dream, Yukito vanishes in blinding radiance. His disappearance coincides with Misuzu's apparent recovery, though his soul seemingly persists as a crow named Sora, appearing later. In the crossover series *Kaginado*, Yukito appears with characters from various Key franchises. His portrayal retains core traits: financial struggles, reliance on puppetry for income, and his short-tempered yet kind-hearted demeanor. The series recontextualizes his original tragic arc into comedic scenarios, like his puppet shows becoming running gags or his interactions with Misuzu and Kano emphasizing absurdity over drama. His role as a drifter searching for the Winged Maiden is acknowledged but not deeply explored, aligning with the series' focus on parody and lighthearted ensemble interactions, reinforcing his identity as a perpetual traveler bound by his family's ancient mission within the multiverse. His design remains consistent: tall with grey hair and golden eyes, dressed in a loose black shirt and jeans. His stringless puppetry is frequently referenced as both his livelihood and a symbol of his mystical heritage.
