Hayato is a college student with a deep passion for crafting video games. His ordinary life takes an unexpected turn when he is suddenly transported into the very world of his favorite game. Upon arriving, he awakens to unique crafting abilities that grant him the power to store materials and construct buildings. Eager to take advantage of these skills, Hayato plans to settle down on a deserted island and enjoy a peaceful, unhurried life. However, his dream of quiet solitude is quickly shattered after he encounters Leena, a young elf girl. Through her, Hayato discovers a startling truth about his new environment: the island is entirely devoid of men. The local female population, numbering around one thousand inhabitants, is in desperate need of his genetic material to ensure their survival. Word of his arrival spreads rapidly, and soon, women from various races begin approaching him one after another, all fiercely competing for his attention and seed. What was meant to be a relaxing escape transforms into a chaotic romantic comedy as Hayato finds himself at the center of an overwhelming harem.
