amazarashi's Akita Hiromu has provided the song "Boku ga Shinou to Omotta no wa" for Nakashima Mika. 

Nakashima approached Akita for the collaboration as "Boku ga Shinou to Omotta no wa" is originally amazarashi's song. It's an important song to Akita because he's held onto it for many years. Nakashima, who received the demo from Akita, commented, "It's a wonderful song. I want this song to be heard until the very end. If not, [the full emotion of it won't be conveyed]."

The song's release date is currently undecided. However, the lyrics are already available on the lyrics website, 'Utamap'. 

In addition, a mysterious countdown has started on Nakashima's official website. Fans can look forward to what will happen once this countdown hits 0.
