Miura-san is a Puchidol, a small, chibi-like creature, who appears in the Puchimas! series and is based on the 765 Production idol Azusa Miura. She is depicted with long blue hair and purple eyes. Among the Puchidols, Miura-san stands out for her calm and mature demeanor, being described as much more mellow than most of her counterparts. Her most notable ability is teleportation. She can travel across vast distances, even to the other side of the earth, and can bring anyone who is holding onto her along for the ride, making her a frequent means of quick transportation for the other characters. This teleportation is tied to her thoughts; she can move to the location of a person she is thinking about, though the accuracy is not always perfect. When she is startled by a loud noise, she will teleport spontaneously and unpredictably to a random location.

Miura-san has a gentle but quirky personality. She enjoys stroking the hair of other Puchidols, though her efforts often leave their hair messy rather than tidy. She also appears to be the only Puchidol with an inclination toward alcoholic beverages. Her relationship with the Puchidol Chihya is notably strained, primarily due to a difference in their physiques. Miura-san communicates with a characteristic call of "Ara!" In terms of her origin within the story, she was discovered by the idols Iori and Yayoi while they were in Egypt, and she was given her name by Haruka. She plays a key supporting role in the daily lives of the 765 Production idols and their Puchidols, often helping them by teleporting them out of jams or across long distances quickly. Her development is minimal in the traditional sense, as her core traits remain consistent, but her role as a reliable, if slightly unpredictable, transport and her calm presence add a unique dynamic to the group.
