ゆるめるモ!
You'll Melt More! (ゆるめるモ!) is a Japanese idol group formed in October 2012. They are also known as Yurumerumo.
Their catchphrase is "We came to loosen everyone’s hearts! We, You'll Melt, More!"
(みんなのハートをゆるめにきました!私たち、ゆるめる、モ~!).
There is a word play between the name of the idol unit and the verb "yurumeru" (ゆるめる) meaning "loosen" or "undo" in Japanese.
They perform new wave and J-Pop songs.
