Does Pluto count? lol...Pluto~ Black Butler

Osaki-Ko, или O-chan, is an Osaki - лиса, фокс spirit. O-chan holds a bond with Tamaki Kasuga and seems to share one with Yuuichi Komura , as well. (Hiro No Kakera)

Yoruichi - Bleach

Keroberos (CardCaptor Sakura)

Mokona (or Black Mokona) from XXXHolic

Ruby From Jewelpet

Nai/Niji from Karneval.

If he counts, then Happy from Fairy Tail.

will idk if the people from fruits basket count because if their hugged by a different gender they turn into the zodiac Аниме witch that they are cursed by and then they turn back into their normal human form

I don't know if he is magical или not but Kumajiro talks.
