Mirai explains dramatically: In the future, all idol performances are generated by AI. But legend says that the "Heartbeat of True Idol Power" was lost over a thousand years ago—specifically, the night of Kirari's 100th solo concert. Mirai has come to witness that power and, if possible, surpass it. But to force Kirari to show her true strength, Mirai issues a direct rival challenge: a three-round "Idol Showdown" to be held that very afternoon.
Mirai uses a device to instantly generate a thousand stunning, futuristic outfits. Kirari, panicking for a second, remembers Hiroto’s words about "feeling over fashion."
