Big Bad Wolf

"Hahaha, you're a stubborn little kid. Did you miss the part where I devoured your village? You think I can't do that to you, but quicker? But, I like you. You have strong fangs. I think I'll raise those fangs of yours. Maybe then you'll be able to have more bite, enough to tear my flesh even."

- The Big Bad Wolf chooses to teach Manon The Big Bad Wolf (ビッグバッドウルフ, Biggu Baddo Urufu), or B.B. (ビービー, Biibii) for short, known more infamously as the Horrible Black Wolf (惨烈黒狼, Sanretsu Kuro Ookami), is a wolf demon known for devouring entire villages and souls to satisfy his hunger, claiming himself to the be the "strongest wolf devil", a title that isn't competed for. Eventually, B.B. took up teaching Manon after devouring her village, due to the latter's persistence in attacking him, despite the clear difference in power.

Trivia

 * Like Manon, B.B. is based off the Big Bad Wolf from the Fairy Tales.
