＊Activity Report: Book Volume 7 now on sale, manga adaptation information posted. Bonus chapters also available.

A man who, despite his privileged birth, had poor family relations, was reborn into a magical other world where the Empire had seized control of the entire continent. He was reincarnated as Asha, the Emperor's eldest son, but due to his lineage, he was not the legitimate heir. If that's the case, then he might as well leave the succession to his younger brother, the legitimate heir, and aim for the close-knit family he never had in his previous life.

Relegated to the edge of the palace, he freely indulged in alchemy, a pursuit no one else paid attention to, making it his hobby. Moreover, he created an intelligent entity impossible by scientific means and named it Sephira. As he raised this intelligent entity, Asha wished to fully enjoy his freedom... but the nobles, suspicious and distrustful of the Emperor's eldest son's activities, began to interfere. Evading them by pretending to be a child at times, and at other times retaliating, Asha expanded the possibilities of the forgotten alchemy at the palace's edge.

「I wonder when I'll finally get to meet my brother.」
