I don't ship Yang x Blake myself, but when I started Akame Ga Kill!, my first thought upon seeing Leone was that she was definitely the secret love child of this ship!
So take Yang's hair, chest, and even some of her mannerisms and fashion sense,
Add in Blake's eyes, some of her look, and, of course, her cat ears and mannerisms,
And you get this bodacious beast assassin! I can't be the only one who sees it, and now you can't unsee it!
