Most racehorses are not usually named when they are born, but only after they are handed over to their owners and their race debut is decided, then their name becomes officially registered. Because of this, the farms often give the horses names when they are foals, that get changed later on.
Air Groove was originally known as Bero, and berobero is onomatopoeia for licking. So "Bero-chan" became a fan nickname for Air Groove.
By the way Symboli Rudolf was originally "Luna" after his mother Sweet Luna.
