If you’ve never heard of Rooster Teeth’s award-winning anime series “RWBY” before, imagine the love child of Harry Potter and “Buffy the Vampire Slayer” in anime form with four badass female characters, each with their own extraordinary powers. Seriously, it’s our new obsession.

The series has already become a bona fide hit online with an average of 2.5 million views per episode ― that’s more than most CW shows, mind you ― and a fan following that outnumbered pretty much every booth at this year’s New York Comic Con.

The new installment finds teenage monster-slayers Ruby, Weiss, Blake and Yang out on their own after their Hogwarts-like school was destroyed at the close of Volume 3.

In this exclusive clip, Ruby and her team battle one of the Grimm, aka Enemy no. 1, sporting her signature (but updated!) outfit and ruby red scythe.

“RWBY” Volume 4 premieres October 22 on Rooster Teeth.
