I was watching Arashi no Shukudai-kun and at the end they promoted a butai that massu will be in.
amazingly i was like 0.0 at first because I didnt expect that to be massu.
more info at Massu no butai
The butai is starring together with Tanimura Mitsuki
The name is called: 雨の日の森の中 or In the forest on a rainy day
Oh forgot to add this. They play will be in tokyo and in Osaka <- failed kanji reading, though I'm chinese, can't read the place for it, but click the link ^^
Here's a picture of the butai from Arashi no Shukudai-kun [note: this is Stormy's team subs, so yeah ^^]
