Description[edit | edit source]
Eight years prior to the events of the main story, Airi belonged to a unit comprised of Kase Mana, Himegami Shano, and Takao Touka. They were incredibly popular; however, creative differences arose among them which resulted in the unit's disbandment. Some time later, fate would bring Airi and Shano together once more when they performed together at D4 FES.
