Ep. 6: Haruna protege Makie com a ajuda de Kirishima enquanto Iona chega e Takao desperta.

As Toujuurou passes away, Haruna decides to protect Makie and asks Kirishima's help for it. Despite facing some heavy opposition, Haruna refrains from killing the attackers and orders Kirishima to flee with Makie, while she creates a decoy with her nanomachines to draw the military's attention. However, the soldiers see through Haruna's trick and start searching for Makie who is distraught with learning that she created a weapon that can destroy Haruna. Once reunited, Haruna, Kirishima and Makie are driven to a corner when Haruna asks for anyone's help, and Iona answers her call. Gunzou is contacted by Kamikage and replies to him that the I-401 and its crew were hired just to deliver the vibration warhead to the US and beside it, they will do as they please. Once the army retreats, Iona takes the three of them to the submarine and Haruna asks Makie to become her and Kirishima's friends to which she agrees. As the I-401 departs for Iwo Jima, Takao awakens in a room, greeted by a mysterious voice who asks for her intentions. (Source: Wikipedia)
