The goblins do not kill their female captives. Instead, they drag them deep into the "suana" – a damp, foul-smelling birthing chamber. Here, the doujinshi shifts from dark fantasy to pure exploitation. The goblins use the adventurers as breeding stock. Due to the goblins' unique biology (often depicted as requiring human or demihuman wombs to reproduce), the captives are subjected to relentless, systematic assault.
The most infamous element of Goblin no Suana is not just the assault, but the aftermath. Over weeks or months, the women are force-fed, drugged, and their bodies are magically or physically altered to better serve as goblin incubators. They lose their humanity, their will to escape, and eventually, their very shape—transforming into immobile, breast-milk-producing "brood cows" permanently embedded in the nest’s walls. goblin no suana
