Groove Coaster will release a new compilation for the upcoming Reitaisai! This time it will be centered on 2nd bosses. There is also a new BUTAOTOME song, which is (surprise! surprise!) Nemuno’s theme, the second boss from HSiFS! The title is “Kodoku na Hana” (孤独な花). Even though it’s not specified, it will be probably a regular vocal track. It’s unknown when it will be available on arcades, but it will be playable at Niconico Choukaigi and Reitaisai.
