The very title “Shirobuta Kizoku desuga Zense no Kioku ga Haetanode Hiyoko na Otouto Sodatemasu” immediately draws attention with its striking impact. The protagonist of the story is Ageha, a plump and soft 5-year-old with chubby cheeks and belly. At first glance, he may seem like just a spoiled child, but he suddenly awakens to the memories of his past life. In that past life, he was a Japanese man who loved cooking, sewing, and singing—an “otomen” at heart. This outlandish premise hints that this is no ordinary fantasy story. The setting is a dazzling alternate world where beautiful elves and gods dwell. Yet behind the glamour lies the reality of corrupt imperial nobles and family discord, creating a world where splendor and bitterness coexist in perfect balance.

The one who changes Ageha’s life dramatically is his half-brother, Regulus. This angelic, fluffy, and innocent younger brother adores him, saying “I love you, big brother,” and warms Ageha’s heart. Astonishingly, he is shown a future where he will one day be killed by the grown-up Regulus. Even so, he refuses to abandon his motherless brother and resolves to “raise him.” Thus begins a story not just of noble life, but of “family restoration.” As a brother, his love and guidance for his sibling are at once comical, touching, tender, and bittersweet. Readers will naturally be drawn into the depths of the story as they accompany the brothers’ growth.

The charm of the manga version lies in its quality that does not betray the expectations of original novel fans. The artwork is beautiful, and the panel layouts are refined, allowing readers to immerse themselves in the story without confusion. Above all, every expression and gesture of the characters is carefully depicted, which in itself is heartwarming. Those who started with the original novel can gain new perspectives through the manga and immerse themselves even deeper in the world. Likewise, those who began with the manga will want to pick up the novel—making it a “dual enjoyment” work, and it’s easy to see why it has so many fans.
