Yes, we have not one, but TWO new original songs! Their titles are Narase (ナラセ) and Jareta Te (戯れた手).
The single is out on various streaming services. Check the links on its Tunecore page! If it’s not available yet, wait until it’s February 1st in your country or use a VPN.
The description mentions that it’s a “pre-release single”, so it’s safe to expect a full album in the future.
In addition, Narase will get a PV later today. Lyrics are in the description, so I’ve already translated them! Check them here.
