Yurumerumo! is a five-member female new wave idol group. Abbreviated as "Mo! (meaning "to loosen up" in Japanese).

The name "New Wave Girls Group" is derived from two meanings: "Yurumelu" means "to loosen up (the tight world)" and "You'll melt more!
Their catchphrase is "We're here to loosen everyone's hearts! We'll melt your hearts more! (We want to make your hearts melt more!)".
