ILLIT, the girl group comprising Yuna, Minju, Mocha, Wonhee, and Iroha, teased the concept for their upcoming release during a solo concert ahead of their comeback. They wrapped up the two-day “2025 ILLIT Glitter Day Encore” at Olympic Hall in Seoul’s Olympic Park on August 8–9.

ILLIT began their tour in June with a show in Seoul, and the run then carried on to Kanagawa and Osaka in Japan through August and September, culminating with this Seoul encore.
