But the point is... Well... Miyabi is something Blake needed: Another Faunus to give her a dose of reality. Sun tried to do it but he was too smitten with her. Miyabi? Well, to integrate her into this...
Miyabi comes from a VERY distinguished Menagerie noble family. Great warriors and statesmen who were pro-human relations and allied with Ghira, against the anti-human extremists. She and Blake were childhood friends. However, the family was almost completely wiped out by a Grimm surge. Her mom died in a last stand to the Grimm hoard and saved Menagerie. Miyabi and her father were the only survivors, and with their family estate and lands destroyed, they lost their power. And with enough accusations of them being human sympathizers, they had to leave. Miyabi joined the Atlasian Specialists, her father became a businessman between Atlas and Vale. Miyabi became a spectacular Specialist and a feared warrior. Head of her own section-She and Winter are friendly rivals.
Blake, to be blunt, resents Miyabi for finding success in the human world and for how incredible she was as a child. She was a true prodigy. But Miyabi would respond, with a bit of anger she's held back:
"Blake... Do you know how many times I wished my mother was still alive when yours hugged you so freely? Do you know how many times I wished my father and I could return home after our exile? My home was completely destroyed. I put my all into becoming a hero of justice, as my mother was. The price is that I can never go home. But you can. Because your parents would welcome you without reservation. They love you and still have the clout needed. But my father and I can never come home. Is that anything to envy me for?"
Blake envied Miyabi's incredible abilities, discipline, and success. Miyabi envied Blake for her family still being intact and her still having a home to return to. The point is not to bash Blake, but to give her some fucking perspective on how big a problem the White Fang is for everyone: Not just humans.
This allows Blake to grow as a character.
@LordofBones if you have any familiarity with ZZZ, it would be appreciated as I am still new to the fandom.
