High school student Kuno Sousuke had a strange dream. In a completely white space, there was a blackboard with the question, "If you could take one thing to a deserted island, what would it be?" While his classmates gave safe answers, Sousuke blurted out "crafting ability."

When he came to, he found himself and his childhood friend transported to a deserted island in another world!? And to top it off, he was granted the crafting abilities he had answered to the blackboard. With his crafting ability, Sousuke easily conquers the harsh island life! Surrounded by a cool, quiet childhood friend, a kind gal, a pure beauty, and a serious class president, his days are comfortable and full of pleasure.

"Sou-kun, with this situation, a harem is only natural."
"You can feel as good as you want."
