ARC∀DIA

 is an idol unit originally formed for the 2016 JAMxNatalie expo.

The unit was brought back to perform at TIF2017 and featured everyone except Yoshida Rinne who was no longer a member at that point.

On January 2, 2018, the staff decided to change the name of the unit to ARC∀DIA, tho no activity has been seen since.
