Miton is a magical creature featured in the series, possessing a spherical white body, two long wings, and a bird-like tail. Ordinarily invisible and inaudible to humans, he can choose to reveal himself. He encounters Yuzuka Hanami near trash, transforming her into a magical girl and initiating her magical involvement. Despite this connection, Yuzuka maintains a reserved distance, often reacting with embarrassment or reluctance to his attempts at closer interaction, prompting his curiosity about her opinion of him.

His relationship with Chiya Sakagami is notably strained; he actively seeks her friendship but consistently faces rejection, frequently resulting in her physically harming him or throwing him down. Miton displays preferences closely aligned with human tastes, particularly a strong desire for delicious food. This shared trait leads to a point of connection with another magical creature, Pochi; discovering Pochi also consumes food sourced from trash fosters a sense of camaraderie between them. Miton's depicted role centers on these interactions with Yuzuka, Chiya, and Pochi, his responsibility for Yuzuka's transformation, and his persistent, though often unwelcome, efforts to engage.
