Wait, why? Every other choice made sense , except that one.
The storyline of tails Rebirth is about the races Human and Gajuma (Beast race) finding a way to coexist, but Humans hate -and often kill- Gajuma and Gajuma hate the humans for that -as well as so many other things the human did to the Gajuma.
Thus the story depicts the hardships that the two races have to understand each other but gradually, the races being able to coexist with each other.

As well as that, the main heroin becomes a Gajuma
Sound a bit like the life of a certain someone? =)
