河野 はるみ

A highly energetic girl who appears out of nowhere and suddenly declares herself to be Takaaki's lover, calling him "darling" and kissing him within moments of introducing herself to him. In reality she is Milfa (ミルファ), a robot with model designation HMX-17b, making her a "sister" of sorts to "HMX-17a Ilfa" and "HMX-17c Silfa". In the original game she borrows the body of a plush toy and is called Micchan in the Himeyuri sisters route./
