I just wanna know how the fuck did this mythical, magical entity came across the fucking Gundam series in the first place? Barring her being an omniscience entity, Spring Goddess' spring is located in a forest near a bum fuck middle of nowhere village. She was hinted to be the entity that was in the classic fable about the woodsman who lost his axe inside the pond.
The only conceivable way she would even know about Gundam series was for some fuckwit brings a number of Gundam merchandise into the forest and near her spring then either dumping it directly into the pond, or left it somewhere on the forest floor for no reason just for the Goddess to find it later by chance.
