As is seen, kitsune do not use their real names when among mortals. The true name of a kitsune can be used to bind the kitsune, banish it, or work spirit magic on it. For the most part, the kitsune will take a name appropiate to the task at hand, or as a joke.

Kitsune are spirits, and can be controlled or manipulated as such, though the stronger the kitsune, the more dangerous it is to try this without their name.

-> A kitsune, who is attacked with magic, and who's true name is used against them, loses their innate resistance to the magic.

Found this on the link below, along with a lot of interesting Kinsune information if interested and you want to check it out.

So...Lydia is probably important to controlling and getting rid of it. Nogitsune are spirits, Lydia as a banshee has a tie to spirits, we just don't know enough specifics yet...
