Rank: Second Lieutenant
TSF: Type-77 Gekishin, F-15J Kagerou

The youngest daughter of the Isumi family. Her parents were away often when she was young so Akira was raised partially by Yayoi, and because Yayoi wanted a little brother, she ended up more boyish than the others.

She's also very independent, attributed to her instinctively learning how to take a step back and remove herself from a situation witnessing the feud between her two eldest sisters or have a harmonious personality like Marika. She's very cheerful, good-natured and looks at things objectively, with a hate for lying. She will always speak up about what she believes is right and wrong.

Masaki and Akira's relationship is closer to brother and sister and they've been fooling around together since they were little, so although Akira is in love with him, she has no idea exactly what a romance between the two could look like.
