S4·E7 Fortress City Pultgayin

MÄR manage to meet up with each other, and Nanashi finds a map. On the map is the island of Pultgayin. The party deduces that this is the lair of the Ghost Chess. Nanashi uses some strange thief skills to get the team onto the island, but his raft is destroyed on the way there, and Allan has to throw the team using his guardian. Meanwhile Kapellmeister steals Alviss away from Belle and Snow. With that success, the Ghost Chess are called to retreat, but before they leave, the Flat Sisters merge with a Ghost Guardian and attack the team.
