She's definitely more then we think...

Don't quote me but I think it is safe to assume that she is/was a Kitsune but she breaks her tails to summon Oni's. Demon warriors to hunt and fight the Nogitsune which then get beat up by her daughter and Scott... The irony.

And yes, Kira would be the last after her mother but maybe her husband (that knows her secrets) says this because he's Korean (right!?) or because they haven't yet talked to Kira about her true lineage. Maybe there's a rite of passage or a secret handshake she needs to learn to be a true Yukimura/ Kitsune.

Or again maybe it just means Mrs. Yukimura has no other relatives then her husband and daughter.
