In this world, there exist vicious monsters called goblins. These terrifying creatures attack people, kidnap women, rape them, impregnate them, and then reproduce. The goblin's next target was the devout pilgrim, Anvil. "Lord, please protect my life from this monster." Anvil's prayers were in vain, and she was captured. Trembling in fear, she leans on her faith in God and prepares herself for death. But what awaited her was something even more terrifying than death: hideous goblins swarming the innocent woman.

Jada, a witch's apprentice, finds herself in a peaceful village. A peaceful countryside, awash in small hardships and small joys, is suddenly invaded by a horde of monstrous goblins. "This can't be happening...!" Jada, a witch but still an apprentice, loses the grimoire she was entrusted with and is instantly captured by the goblins. Her small body is trampled by the giant, mutant goblin, and with no way to escape, she can only cry out. She conceives, gives birth, but it doesn't end there.

Goblins. They are vulgar monsters, ubiquitous... at least, that's how humans perceive them. On this day, a young adventurer named Ilari set out to slay goblins, hoping to make a name for himself. Unaware that this was the beginning of a tragedy... "I will hunt down every monster in this nest!" Ilari was utterly ignorant and foolish. It was too late to realize his own inferiority to the goblins.

Sayuki, a female samurai who arrived from a distant land across the seas. She possessed beautiful eyes and a striking physique that captivated men, but her nature was that of a beast. Aiming for unrivaled status, she was a master trained as a warrior, her sword honed to a razor-sharp edge like a katana. "Please don't excite me anymore". But goblins don't care about a target's personality. If a female is exceptional, they attack in packs until they're sure to take her down.
