Sonogo no Succubus-san

True love knows no bounds, not even for a creature of the supernatural. Ruru Katsurada, a succubus who has harbored deep feelings for her partner since their high school days, finally married the man of her dreams. For forty years, their union has been nothing short of idyllic, proving that the classic romantic comedy between a human and a demon can endure well beyond the initial blush of romance. Together, they have built a life defined by decades of unwavering devotion and smooth sailing, defying every expectation placed upon a relationship so inherently unconventional. However, time inevitably brings new challenges to even the most perfect partnerships. Now navigating the realities of a long-term marriage, Ruru finds herself quietly struggling with an unexpected dilemma: a growing lack of physical intimacy. For a succubus whose very nature is intertwined with such closeness, this emotional and physical distance presents a deeply personal conflict that threatens to disrupt their otherwise harmonious life together. Set four decades after the typical conclusion of a supernatural romance, this one-shot explores the tender, uncharted territory of enduring love, asking what happens when the honeymoon phase has long faded but the heart still yearns for connection.
