I collaborated with ZAQ, an anisong artist, on vocals. The band lineup includes Ryunosuke Yamagishi on guitar, Ryo Kudo on bass, Yuya Ishii on drums, Yuuki Kishida on piano, and the Yoshida Uchuu Strings on strings. The recording and mixing were done by Kenta Ino, and mastering was done by Masaoki Moroishi. "Happy End" is finally completed.
