Jun stopped running from the world. Shinku stopped running from what she's done. The second season doesn't care about explaining the Alice Game, it cares about whether these two can live with themselves after everything they've broken. The dolls feel less like collectible pieces and more like people who have already lost too much. It moves fast enough that you never see the filler coming, then punches you in the chest with a kid learning to be human again, one conversation at a time.

Summer break arrives, and Jun Sakurada spends it studying in the library, catching up on the time he lost while shut away at home. His doll partner Shinku, meanwhile, is troubled by nightmares and by the pain and sorrow of having defeated Suigintou. After waking from one bad dream, she follows Suigintou's wandering spirit companion and learns that Barasuishou, the seventh Rozen Maiden, has awakened. None of the sisters has ever seen her before. Shinku takes her arrival as a sign that the Alice Game is nearing its end, when the dolls will have to fight one another, and she begins pulling away from the others. Victory would cost her sisters their lives. The series mixes supernatural action and drama with comedy as the dolls face that looming battle.
