Laki (MonstlloW (モンストロ)) has debuted his solo project on 2/19 with the concept of “2ND ACTION” and has released a new song, Akumu (惡夢). *I’m not sure if it’s officially called “Laki solo project 2nd ACTION” or just Laki solo project, so feel free to correct me.
Different versions of the song have been released through a set schedule (seen below), with a Vocaloid version being released on February 20th, an artist photo on the 23rd, the official version through a music video on the 27th, and (presumably) a live version on the 28th! The project also credits Souma (XANVALA) on guitar.
Laki also has a Youtube channel where he performs original songs and covers.
