About
The idol group that shocked the music scene the moment they debuted.
【VORTEX】
Armed with overwhelming vocal ability, unique performances, and intense personalities where no one gets overshadowed, they climbed to the top of the idol world in an instant.
The sight of them turning concert venues into a whirlpool of frenzy eventually led people to call it the "VORTEX Phenomenon."

It wouldn't work if even one person were missing.
The moment their talents intersect, the world is swallowed by their vortex.
— Diverse personalities, one vortex.
At the center of that frenzy is VORTEX.
