My bet would be Tengoku(Heaven). This is because at the meet the family session with Kira and Scott, Kira's father has stated the Kira's mom family line was a very special one.

With that being said, the Heaven attribute Kitsune is considered a "holy"/"priestess" of sort among the Kitsune species. Hence this should go in line with whats so special about Kira's family line.

As to her sucking up electricity, well if she is considered heaven, namely celestial/sky, it would be natural for lightning to also be related to it.
