Slime Tensei.: Daikenja ga Youjo Elf ni Dakishimeraretemasu

The legendary Great Sage Marlin Endlight, a mage whose wisdom and power were renowned across the realm, meets his untimely end—only to awaken in the most unassuming of forms. Rather than passing into legend, he finds himself reincarnated as a humble slime, stripped of his former glory and reduced to a gelatinous blob. Yet fate, in its peculiar twist, offers him a lifeline of love: he is taken in and bound as the familiar of his very own daughter, a young elf who refuses to let go of the father she has only just regained in spirit, if not in body. Now existing as her squishy, magical companion, Marlin must navigate the bizarre realities of his new existence while grappling with the fierce protectiveness of a daughter who now considers him her most treasured pet. Their quiet, everyday life together is soon disrupted by the looming threat of his stolen mansion—a place filled with his life's research, secrets, and the remnants of his legacy. Determined to reclaim what is rightfully theirs, Marlin and his daughter set out on an unexpected adventure across the countryside. What unfolds is a heartwarming and whimsical journey of familial bonds, where a slime with the mind of a sage and a devoted elven girl face bandits, magical mishaps, and the trials of reclaiming their home, all while discovering that even the smallest creature can hold the greatest love.
