Teen Idol, also known as TeenIdol due to space constraints and Luminary in the 3DS remake, is an Advanced vocational class in VII.
The Luminary is a master of entertainment. They are masters of comedy, dance, and song. It is so popular that even monsters are charmed by his/her star power, which may prevent them from attacking. At higher tiers, monsters are more likely to be charmed by them. To become a Luminary, one must master the Jester, Dancer, and Troubadour classes.
