Otsuka Ai released her latest digital single "Kuroge Wagyu Joshio Tanyaki 680-en (maeshima soshi Remix)" on November 18. 

Since August, the singer has been releasing a remix of her song every month. As the fourth part of this project, she has released her seventh single "Kuroge Wagyu Joshio Tanyaki 680-en" (released in 2005) remixed by music producer maeshima soshi. He commented, "By being involved in this song, which was always on TV back in the day, I was able to revive Otsuka-san's voice and the song's worldview while incorporating my own color. Please enjoy her cute, yet bewitching voice fused with a chill atmosphere." 

The music video is an animation based on Otsuka's movements in the song's original MV.
