Once upon a time there were many yatschens in the world. Now there is only one left - Oleg, the son of the archdemon Lalartu. Having survived many adventures, having gone through death, having been a man and a demon, he still remains himself... he tries, anyway. We left Oleg on Earth-1691, in the Vatican - it was there that he finally defeated the nightmare Pazuzu and met even more the nightmare Rrogaldron. Having experienced so much, Oleg hoped to finally settle down in a quiet haven, to live a little calmly... Yeah, now.
