Black Bird Vol. 4 (manga)
Despite the constant danger Misao finds herself in, she's determined to
stay by Kyo's side no matter what happens. But a chance meeting with one
of Kyo's best friends shows her just how hard a human-demon
relationship can be.
Tadanobu, heir to the Kitsune clan, gave up everything to be with his human girlfriend. But now he is being forced to take on the clan leadership and abandon his love--and it's all Kyo's fault!
