As Rain, a male B-Rank adventurer, was exploring a dungeon he unlawfully entered, he stumbled upon an Ancient Class artifact. Selling it could secure his retirement, but his joy did not last long. The item's magic not only gave him the strength of an S-Rank adventurer but also transformed his body into that of a woman. Before he could comprehend the shock, he received an unexpected invitation to a female-only group called "Crimson Heaven."
Will Rain be able to return to his original form and live a peaceful life again?
