Mayphia was a visual kei band in Nagoya. They were active from 1999 to 2001 and are now disbanded.
On who Aoi is rumors that went around before - Aoi from ayabie definitely confirms multiple times in his blog ~2007 that he was never in this band:

Safe to say they are completely different vocalists who look similar as per the note on the timeline. This band was active in Nagoya while Aoi from ayabie was in both ZercVelle and Le vi-sage around the same period of time in Tokyo from what I understand.
