JUNK forms.
Note: Nagisa (凪沙) and Shingi (神葵) were said to have been part of a band named JUNK, which would have been active in the same region.
The two lineups listed here are confirmed; it's unclear if Nagisa/Shingi used different names, or if they were part of a third lineup (or an entirely different band).
