The agency also released a couple of nostalgic teaser posters reminiscent of their heyday to build excitement among fans for their upcoming return.
The quartet will kick off their reunion with concerts in Seoul in early October, followed by performances in Osaka and Tokyo through December.
Meanwhile, the agency also revealed plans for another quartet BLACKPINK. The now globally-popular K-pop outfit, who renewed their contracts late last year solely for group activities, will come together again to embark on a world tour slated for next year.
