Yákov's Rope (English)

The lore is serious, even if the comic is not:

Yákov Kuznetsov was a powerful military leader from Russia who, due to her darkest and most insane actions during the war, was sent to Hell after dying from multiple gunshot wounds. There, she became a demon - but was given a rare opportunity to return to the human world under one strict condition: she must not commit any acts related to her violent past (no killings, suffering, agony, or sadistic pleasures).

Despite being allowed back into the human world, she is not alone. She is accompanied by a guardian and warrior angel named Archel Farick, who serves as both her emotional and physical support. His mission is to help Yákov control the twisted, violent thoughts that still lurk in her mind - and guide her toward redemption so that the gods may one day forgive her past sins.
