THE UNLIKELIEST OF FRIENDS The mansion where Professor Osakabe and Makie live is under attack, and nobody is happy about it: not the government, not the residents, and not even the attacking soldiers, who find themselves face to face with Haruna and learn firsthand that even without their battleships, the Fog's mental models are a force to be reckoned with! Haruna's world has been turned upside down since the I-401 destroyed her and Kirishima's battleships. She's learned that Osakabe Makie has also become her friend. And now Haruna is quickly learning the meaning of both "friendship" and "loss"-concepts she's never had to grapple with before.
