The gang visit a place called Artemay Tower, after Xellos tells them a story spooking them of their wits. He tells how a guy lived in the tower, with all dolls and fell inlove with a villager. When the girl went missing, angry villagers went to the tower, only to find all the dolls has the girl (who he fell in love with) had all her face on the dolls. Thanks to the chef at the inn they were in, they get some cute costumes and head for the tower. They disreguard the dolls, only to have the dolls scare them (in broad day light.) They figure out about the costumes, and uses it, as they enter the tower. The dolls aren't arrive of them, and they get a visit from the guy from the story named Joe. After a few twists and turns, they manages to kill the real monster, who was acting as Joe's doll. Back at the end, Lina is upset at Xellos saying that they did that for nothing, thinking that the Claire Bible could be actually up there. But the others are happy with their cute costumes.
