Shuffle!? Friends! - S2.E5

With three jeweling dresses now in existence, the other idols begin wondering how to find their own unrefined jewels. HoneyCat and Reflect Moon both go searching for jewels and end up stumbling upon an old shrine. The shine is found to contain a magical stone which causes the idols to mix up their Friends pairs. Everything starts out great with the new pairs having new experiences, until the stone's power turns malevolent.
