Absolutely delightful faff, an analog OVA oasis of cheerful 90s character designs, sci fi mecha parody light yuri goodness. Features giant sweat drops, frequent SD moments, grating high pitched voices, comic exaggeration turned up to ju-ichi. I'm unfamiliar with the PC engine games so the plot was totally nonsensical, fortunately at two episodes the way the OVA just blows through all these characters and backstory results in a kind of delighted bewilderment. It's so unserious I can't imagine that knowing the deep GFY lore would really have enhanced my experience. For fans of stuff like Galaxy Angel this is a dai-recommendation desu Fiending for more MS girl adjacent media.
