Otsuka Ai and AKKOGORILLA will digitally release their collaboration single on May 12.

The two hit it off after co-starring in the streaming event 'LIVE HUMAN' last June. Then they worked on three songs "Aibiki," "Hi-Navi," and "Matatabi." 

Otsuka commented, "I felt that Akko-chan's voice has a unique charm that mixes incredible strength and sadness." AKKOGORILLA reflected, "I still can't believe that I wrote songs with Otsuka Ai-san whose songs I used to sing at karaoke."

Prior to the single's release, which includes the three songs, its lead track "Aibiki" will be available for download on April 28.
