It could be from some sort of extreme horror writer's imagination. Writers often come up with very dark and disturbing concepts to shock their readers.
The idea of a'snuff woman' in such a violent context is extremely disturbing and often related to dark and fictional horror concepts. There are no real - world instances of this. In horror literature, perhaps it could be part of a very dark and twisted tale where an evil entity or sadistic character subjects a woman to this brutal act, but this is pure fictional horror.
No. This is an extremely dark and unethical concept, so there are no well - known stories with such a plot. Mainstream literature focuses on more positive, moral, and relatable themes.
It contributes by expanding the world - view. The 'Made in Abyss' series has a vast and complex world, and 'Old Stories' can show different aspects of it. It can introduce new characters or events that are related to the main story, thus enriching the overall narrative. It might also give a better understanding of the history of the Abyss, which is crucial for a full appreciation of the main series.
The answer is yes. Made in Abyss began as a novel. This original form allowed the creator to lay out the core ideas and storylines that were later brought to life in other visual and narrative formats.
The Made in Abyss manga is on hiatus for now. Maybe the author needs time to flesh out the story or there could be other behind-the-scenes factors affecting the schedule.
