Estel is one of the characters from Pop'n Music: Usagi to Neko to Shounen no Yume.
An elven that once lived alone in a town where nature and technology coexisted. But then one day, she crafted an arm out of the lost technology of her ancestors...
Estel's appearance is a light-skinned elf with green eyes. She is born with walnut blonde hair, with half of it tied into an oval-shaped bun, and decorated with a black string. Her debut attire is a white dress with orange and green square patterns, overlapping each other, and pale coffee brown boots with platinum soles. Other accessories around Estel are a left glove that matches her boots, a matching vest layer, a white shawl, a gray metal shoulder pad, an orange gear brooch with a light yellow rim, and a metallic right gauntlet with orange and light yellow highlights.
- Estel shares her birthdate with Miyabi-san.
- The robot that appears in Estel's animations looks like a prototype of Navi-kun. This could hint that Estel might be the creator of Navi-kun.
