5. エーフィ Eifi (Espeon)
This one is inspired loosely on one yokai as the only similarity it has is that it looks like a cat, has a split in its tail and is psychic. The yokai counterpart is the Nekomata.
A nekomata is a very old cat that with its old age became a yokai with psychic powers. It has a tail that is split in two, could summon fireballs and can control corpses like a puppet. It can also use its powers to blackmail and enslave humans to do its bidding. Like I said very loosely inspired.
