Rozen Maiden Collector's Edition manga volume 5 features story and art by Peach-Pit.

When Jun accidentally orders a magical doll named Shinku, he gets swept up in a supernatural adventure beyond his wildest dreams! Shinku and her sisters are facing off against each other for the title of 'Alice,' but only one of them can win this deadly game.

When a major threat rears its head only the gardener twins, Suiseiseki and Souseiseki, can stop it. But since Sugintou has Souseiseki's Rosa Mystica, Suiseiseki must strike a deal with Sugintou to get it back. Sugintou is intrigued, but she's not going to give it up easily. Can the twins afford the cost? For that matter, can they trust Sugintou to hold up her end of the bargain? Meanwhile, the two Juns each face their own ordeals to return to their original worlds. What does the Jun from the 'unwound' world truly wish for?
