Mako, who is revealed to be a childhood friend of Saori, joins the others on the tank, which soon comes across a perilous bridge which Hana has trouble navigating. After a hit from enemy fire knocks Hana unconscious, Mako takes over as driver and manages to safely navigate to the middle of the bridge. There, they manage to find perfect cover from enemy fire whilst Yukari takes out the enemy tanks, securing victory for Miho's team. Whilst celebrating their victory, the team decides that Miho should be the commander, with the roles of radio operator, gunner, driver and loader assigned to Saori, Hana, Mako and Yukari respectively, before going shopping for things to make the tank more comfortable. Later, the students are informed of an upcoming friendly battle against St. Gloria's Girls Academy, of which Miho is assigned as the commander for the school's team.

As Miho once again uses the radio interceptor to lure the rest of Saunders away, the Duck Team manage to find Alisa's tank and lures it into an ambush by the other Ooarai tanks. After learning the truth about the radio interception, Saunders' commander Kay sends an equal number of tanks to pursue Ooarai as they chase after Alisa, taking out both the Rabbit and Duck teams. Despite the grim situation, Miho calms her nerves and urges her teammates not to give up. Climbing up to the top of the ridge, the Anglerfish Team manage to take out Alisa's tank before they are taken out themselves, winning the match. After Kay commends Miho on her victory and takes her leave, Mako receives a call that her grandmother has been taken into hospital. Hearing about this, Maho allows Mako and Saori to take her helicopter back to Ooarai to see her.

Ooarai is doing well but the need to for additional tanks leads the group to searching the entire ship for new firepower.
