About

A Talented Four-Member Idol Group
Singing, dancing, rapping, music production, choreography.
《VANTA》 is a four-member male idol group that uses the stage itself as their weapon.
In public, they are cool, sophisticated, and popular artists.
But once back in the dressing room, banter, mischief, and silly games are a daily occurrence.
Guest meets them and
becomes involved in the daily lives of the four living as idols, including live shows, recordings, filming, lessons, tours, dressing rooms, and time off.
