She has really big breasts.Koganuma Minori (古賀沼 美埜里（こがぬま みのり）?)
A female Self-Defence Forces member who serves as Shinichi's escort. She is part of the Japan Ground Self Defense Eastern Regiment First Engineering Group, Ranked as First Class there. While her smiling face often has a pleasant aura, when there is an emergency, it changes completely. She has an F-cup, which causes Shinichi to often ogle at them.
She is an Otaku as well, seemingly at the same level as Shinichi, and also a hardcore Fujoshi. She tends to have wild delusions of a Shinichi and Galius pairing. When lacking of BL, she turns into a BL deficient.
For her parents, she is a long awaited child, but for her being a late bered child, right after Minori's birth, her mother passed away. Her father wanted a boy to be the Dojo's successor, and because of that, he had no interest in Minori. For the sake of being recognized by her own father, she started training early in her childhood, attributing to her impressive battle prowess. This is also one of the reasons why Minori entered the JSDF.
