Rentaro Aijo has suffered through one hundred romantic rejections by the time he reaches high school, prompting him to visit a local shrine to pray for better luck in his love life. There, the God of Love appears and delivers a startling
revelation: due to a divine scheduling error, Rentaro is fated to meet one hundred soulmates during his high school years. Furthermore, the god warns him that if any of these soulmates fail to reciprocate his love, they will suffer a tragic, fatal accident. Determined to protect these girls at all costs, Rentaro accepts his monumental and absurd destiny.Right away, Rentaro’s life completely upends when his first two soulmates, the hyper-competitive Hakari Hanazono and the refined, secret-pervert Karane Inda, confess to him simultaneously. Refusing to choose just one and break the heart of the other, Rentaro boldly declares his intention to date both girls at the same time, securing their mutual blessing to form a consensual polyamorous
relationship. As the series progresses, this unconventional romantic dynamic rapidly expands into an ever-growing, highly chaotic family.Driven by his absolute devotion, Rentaro meets, wins over, and welcomes a wildly eclectic array of women into his life. His soulmates include an absent-minded chuunibyou, a perpetually sleepy young genius, a masochistic stern disciplinarian, a mother-daughter duo, and even a futuristic AI robot. Each girl possesses distinct eccentricities, intense insecurities, and unique emotional burdens. Rentaro’s primary motivation remains steadfast: he strives to provide an unwavering, deeply attentive, and equal amount of love to every single partner, ensuring that no one feels neglected despite the sheer volume of relationships.Dramatic and comedic events continuously test the logistical and emotional limits of the sprawling harem. The girlfriends frequently clash due to their clashing personalities and intense jealousy, yet Rentaro’s sincere, self-sacrificing dedication invariably unites them. He goes to ridiculous, heroic extremes—battling tyrannical school councils, orchestrating massive dates, and fighting off absurd cosmic threats—just to ensure their happiness and safety. Rather than descending into pure hedonism, the narrative focuses on building a remarkably wholesome, supportive, and surprisingly sweet domestic dynamic. Ultimately, Rentaro embraces his chaotic reality, continuously expanding his heart and his household as he races toward his ultimate goal of making all one hundred of his soulmates genuinely, deeply happy.
