Arpeggio of Blue Steel -Ars Nova-/Tear Jerker

After Makie learns that her new (and, at that time, only) friend Haruna is the mental model of a Fog warship, she flees (with Kirishima's teddy-bear form, not knowing she's a mental model as well). Haruna thinks it's because humans fear and hate the Fog, and resigns herself to sacrificing herself to allow Makie to escape. She suffers serious damage from the pursuing soldiers because she refuses to deploy her lethal weaponry, even though it would make short work of them, because Makie wouldn't want her to be that way. Then, we hear Makie's side of the story: she's not afraid of Haruna at all -- but she thinks that she doesn't deserve to have Haruna as a friend because she designed the vibration warhead intended to kill the Fleet of Fog, so she runs away to draw the soldiers after her and let Haruna escape.
