I’m going to dig in and ask the real questions nobody else is asking here: how long ago did interdimensional horse reincarnation start happening in uma musume? And if long enough ago, did it only occur with Homo Sapiens Sapiens, or could it have happened with human adjacent species such as Neanderthals? For that record, could there be other reincarnation fusions like magpie/salamanders or cicada/crawdads out there?
