ドーナツホール (Donut Hole)

Background
Hachi's latest song after almost three years of absence in the VOCALOID community. On the surface, it is about a girl who wants to remember her past self's name, as shown in the video (Up to a person's interpretation), but can't. At the end of the song, the girl remembers the forgotten name. The lyrics are vague as to a deeper meaning and many diverse interpretations have been created.

This song is featured on the album Yankee, covered by Kenshi Yonezu.
