Underbeasty

Underbeasty (アンダービースティー) is a visual kei rock idol group.

They debuted under the name TYR☆FING in January 2014 and disbanded in May, reviving as Underbeasty in November with all members returning except Uehara Rina and three additional members joining.

They also perform under the name Underbeasty (spelled あんだーびーすてぃー), where they have a royal, more orthodox idol theme, to directly counter the rock style of the main group.
