You and Idol Precure♪

After watching the first sunrise of the new year from the hill by the Heart Tree, Uta and the gang get together at Tanaka's house. At Tanaka's suggestion, they all transform into Precures before beginning their New Year's Party, but then the doorbell rings as if someone was waiting for that moment.

As black petals flutter and anxiety spreads throughout town, Uta proposes holding a concert and inviting a "special guest."

Darkine appears in Hanamichi Town as a giant shadow.

Overwhelmed by Darkine's power, Uta is locked away in pitch-black darkness. Standing alone in a silent world created by Darkine's darkness, Uta summons something she can rely on.
