Maya and Kyōsuke go on a mission to rescue Kazuki at Moldova base. At the same time, the Neo UN fleet invades the Alvis base, trying to secure the island by taking control of the red female core, revealed to be a Coagula Type Festum, however it has left its container. Meanwhile, Yōji manages to persuade Mjölnir, the Master Type Festum which has assimilated Akane Makabe, to give the Fafner Mark Sein to Kazuki. Yukie, as well as Col. Dudley Barns, questions Fumihiko and Sōshi concerning the whereabouts of the female core, but the latter two are unaware of its current location. While Kyōsuke fends off the Festum in the laboratory, Yōji gives Maya the research data of the Fafner Mark Sein.
