STARLIGHT is the new fictional Japanese idol group who provide the singing voices for the main characters in Aikatsu! 5, and its second season, titled Aikatsu! 6. They provide the singing voices for the Data Cardass Aikatsu! game starting from the 2017 series onward.
Like the unit's predecessors in AIKATSU☆STARS! and STAR☆ANIS, all of the members of STARLIGHT provide the singing voice at least one main character in the Aikatsu! universe, and are credited only by their given name. A voice comparison chart is on the page to help determine how the members' voices sound.
- Risa Kanemaru (as Tsukiko Kanzaki) A younger, higher-pitched Mizuki.

- Yasu Enomoto (as Nori Chiura) A higher pitched Kii
- Hanae Ishido (as Amaya Ōtsuka) a slightly darker Seira.

- This is the first real-life Aikatsu! unit to not have any returning members from AIKATSU☆STARS! or STAR☆ANIS.
