Aimer has revealed the MV for her new song "Deep down."

This is the ending theme for the ninth episode of anime 'Chainsaw Man.' It's also the title track to Aimer's mini album that was released on December 14. For the video, Kojima Oudai (director O) utilized a technique called VFX to fuse reality with a virtual space. 

On the song, Aimer commented, "Not for the chainsaw man, but for her. A song dedicated to the ladies."
