Yūto Kazama appears as a human character in the anime series *Rilu Rilu Fairilu: The Fairies' Door* and its sequel *Rilu Rilu Fairilu: The Magic Mirror*. He is a high school student and violinist, distinguished by his yellow-themed design and green eyes. His family includes his mother, Julia Kazama, and an unnamed father.

During a visit to the human world, the Flower Fairilu Rose discovers Yūto practicing violin in a field. His music captivates her, compelling her to return the next day. Yūto reveals his awareness of Fairilu and warns Rose of human-world dangers, urging her to leave for safety. This encounter forges their connection, with Rose later calling him her "human buddy."

His Fairilu counterpart, Juli, features in the spin-off *Tell Me, Magical Pendulum ~Rilu Rilu Fairilu~*, though Yūto does not appear in this series.
