Haruka and the others are at the beach, but this is no vacation – they are performing activation tests and pilot training for Imber and other iDOLs in the same town where Imber and Nebula were manufactured.

The iDOLs and their pilots go through harmonization, fine-tuning the machines to match their pilots. Iori’s numbers are the best she’s ever attained, pushing Makoto out of being Nebula’s master.
