If you go at Reitaisai, you can play Groove Coaster and there will be new songs!
Kami no Hi (カミノヒ) is an arrangement of Nuclear Fusion by COSIO (ZUNTATA) and is sung by Ranko. While Karisome (カリソメ) is yet another arrangement of Hartmann’s Youkai Girl by Comp, but this time Ichigo (Kishida Kyoudan) is on vocals.
These songs will be released on a CD which will be distributed exclusively at the event. It’s currently unknown if the album will be also released in other ways.
