Fox and Wolf - Katherine Woodbury - Bog

Ami Tokudaiji is a kitsune (a Japanese werefox) from one of Japan's wealthiest families. But her mother has been disinherited and now their meager fortunes are threatened by a financial scandal. Yuki Yamakawa is a werewolf with the bad habit of picking fights with the wrong people (but usually for the right reasons). When the two of them end up in the same homeroom class at Osaka's most exclusive girl's school, Yuki is determined to mend her ways and make Ami her new best friend. That is, if they don't kill each other first.
