In the world of Alfheim, home to a race of elves where only women exist, the sacred Holy Tree that gives birth to new life is withering. Facing extinction, the elves summon an ordinary young man named Yuuichi from modern Japan after his night shift. According to prophecy, he is the "Messiah" whose human seed can restore their fertility and magic power.

Yuuichi is immediately surrounded by eager elves: the cheerful Ruche, the wise elder Nol who brought him there, and the elegant high elf Phyllis. They all beg him to impregnate them. As he explores the forest, he encounters mysterious dark-skinned elves and their aggressive dark elf counterparts — Elda the warrior, the powerful general Delva, and the strategist Mizury.

What starts as a conflict between light and dark elves over who gets to claim the savior evolves into intense breeding competitions, seductive traps, and eventually a peaceful harem life. From passionate first meetings and aphrodisiac-fueled confrontations to costume play and group encounters, Yuuichi must satisfy every lewd elf and dark elf in the forest. Pure fantasy erotica packed with huge breasts, creampies, and endless elf sex
