"If you were reincarnated into a magical world, what kind of life would you lead?"

Upon reaching the age of nine, dozens of children across the Growing World regain the memories of their previous lives on Earth and try to come to terms with their new situations. Met with a strange and magical world, finding a practicable answer to this question became an urgent matter for many.

 
Discovering his new world's access to magic had stunted the development of Empyrical Science, Doro's answer is to recruit older crafters and researchers to start an industrial revolution while remaining under the radar by letting others take credit.

Being reborn alone, in a strange forest, and in the body of an owl, Emi found herself with a different set of priorities. Somehow recovering a pair of arms, reuniting with her friends, and funding her endeavors by taking credit for Earth's music.

They are not alone in this, as the natural disaster behind their death claimed a great number of their former fellow students, all with their own dreams and hangups.

Although their first lives were cut short, a new beginning awaits them. Watch their first steps as they settle into their new lives and start changing the world, and see whether their decisions get them branded as trailblazers or lunatics.
