Chapter 771 - Baba Yaga

Baba Yaga is the nickname that was given to the character John Wick. Although it's explained "slightly" differently in the movie, Baba Yaga is the East Slavic death goddess, with the appearance of a hideous hag. She is also known as a grandmother witch or an ogress who steals, cooks, and eats her victims, usually children. Sometimes she's also capable of dark magic such as necromancy.

John Wick is great movie. If you haven't seen it yet, I'd recommend it.
