Lydia is a 200 y/o kitsune who'd do anything to protect whoever she is assigned to.

-each of her tails have a maw and a pseudo stomach (Wich won't digest prey , no matter what)

-her horns can and are used to keep evil spirits away (even physical entities sometimes)

-she can die up to 9 times each month , Wich will cause her body to simply....plushify! and , of course she will reappear next to who she is guarding ! A little help : each time she dies , one of her tail turns white -so it's easy to know when she has to be prudent.

-if who she's protecting is in danger of death and that she is unable to help (weither because she got badly hurt or can't reach ) , she'll be forcefully transformed into a MASSIVE black wolf with red bloody paws. Once the threat is dealt with , she'll return to normal. However , this does have a great chance at ending up in her death.
