Among the gifts delivered by Eila, including a FP-45 Liberator charm, the Witches discover some microfilms containing secret information about the Warlock, which was destroyed by the Strike Witches in Brittania after it went berserk. Thinking that a secret weapon is being sent to them among a cargo shipment, Waltrud Krupinski, along with Hikari, Naoe and Nipa, are dispatched to assist a Brittanian Witch in escorting the delivery fleet to Murmansk. While Naoe and Nipa test new Striker Units at the Murmansk base ahead of the fleet's arrival, Waltrud drinks liberal amounts of "grape juice" and develops a hangover. When a group of Neuroi suddenly appear before the Witches, Waltrud sobers up and assumes command of the mission. After Waltrud destroys the Neuroi, she is struck by some flying debris but is protected by the charm that Hikari had given her earlier. As Waltrud is hospitalized, the Neuroi regenerates itself, dragging Waltrud's Striker Unit with it.
