The Diamond Friends Cup is about to start with Honey Cat verses Pure Palette. But Pure Palette is worried they won't be able to pull off a Miracle Appeal despite practicing. Honey Cat reveal that they too have been unable to replicate their Appeal in training so both teams work together to unlock the secret of the Miracle Appeal.

The next round of the Diamond Friends Cup sees Reflect Moon go up against Love Me Tear. But despite Sakuya's divination they'll be victorious, Kakuya is still worried she'll never be able to match her sister's skill as an idol. But it's not only Kakuya that's worried, Mirai notices Karen is having her own doubts.

Aine and Mio think about what more they can do before the final round of the Diamond Friends Cup against Love Me Tear. To their surprise Mirai shows up at Aine's home and tells the girl about Karen. Karen has been holding back her abilities as an idol ever since she and Mirai became Diamond Friends because the Friends unit they competed against dropped out, fearing they'd never be able to match Love Me tear. Mirai wants to go all out against Pure Palette and unleash the Love Me Zone, Love Me Tear's own version of the Aikatsu Zone, but fears that Karen's feelings will prevent it. However, Aine comes up with an idea to hold a sleepover at her house so both Friends groups can get to know each other better, and hopefully convince Karen to open up about her feelings.
