Ep. 4: Mea repara una muñeca para un espíritu misterioso mientras sus hermanas desaparecen en un sueño encantado.

4

Alone in the mansion's Christmas shop, Mea meets an unnamed girl who insists that Mea fixes her doll. When the sisters return, the girl vanishes, leaving her doll behind. Although she was initially reluctant, Mea decides to repair the mysterious girls' doll. The next day, Mai and Mii disappear as they are exploring an abandoned village. When the girl returns to retrieve her doll from Mea, she mentions the abandoned village when asked where she comes from, before once again disappearing. After Ai too vanishes, the mystery girl reappears. She leads Mea to the sisters, who have been placed in an enchanted dream about their greatest desires by the girl, who is a lonesome spirit. She attempts to enchant Mea as well, but fails when she realizes that Mea has no dreams. With that, the sisters are freed from their enchantment. (Source: Wikipedia)
