Kirov: "That's right, Bismarck. It's been a while, hasn't it?" Enterprise: "Bismarck, you know this shipgirl?" Bismarck: "Yes, unfortunately. Kirov is a Soviet shipgirl from the Northern Parliament. We crossed paths during one of my previous adventures." Enterprise: "What are you doing here, Kirov? And why did you destroy our storage room?" Kirov: "I apologize for the mess, but I needed your attention. Something important has come up, and I believe it concerns all of us." Belfast: "What do you mean?" Kirov: "There have been reports of a new Siren threat emerging, one that surpasses anything we've encountered before. It goes by the name of 'Leviathan.'" Enterprise: "Leviathan? I've never heard of it. Is it more powerful than Purifier?" Kirov: "That's what the reports suggest. Its strength and abilities are beyond anything we've faced so far." Kitakaze: "We can't afford to ignore this, then. If it's a threat to all of us, we must face it together." Bismarck: "Agreed. We need to gather our forces and come up with a plan to defeat this Leviathan." Enterprise: "Very well. Kirov, thank you for bringing this to our attention. We'll need your help in dealing with this new threat." Kirov: "I'm glad you're willing to cooperate. Together, I believe we have a chance at stopping Leviathan before it becomes a greater threat." (With their priorities shifting, the shipgirls quickly regroup and start making preparations to face this new enemy. Leviathan may be powerful, but with unity and determination, they are determined to protect the base and the world from its destructive influence.)
