Koshchei The Deathless (2018) #6

Koshchei retells his final encounters with the Baba Yaga, and he and Hellboy part ways. Mignola returns to Hell and to the bizarre folklore that's filled some of his greatest books, reuniting with one of his favorite collaborators, Ben Stenbeck (Frankenstein Underground, Witchfinder: In The Service of Angels, Baltimore).
