On his way home from a part-time job, the protagonist dies in an unfortunate accident and is reborn as a baby named Alec in a fantasy world. In his previous life, Alec was abandoned by his real mother and suffered greatly, so this time he resolves to live freely. However, he soon learns that in this life too, he is destined to be abandoned. Together with his cute younger “sister” figure, Liz—his companion in fate—Alec throws himself into intense magic training! Even when the fated day comes and he is left behind in a deep forest, he and Liz aim to escape using the magic they’ve mastered. The two little ones eventually make it past the forest and arrive in the Hohenheim territory. There, they start their life as adventurers with the help of a kind young man named Jin, and even save a town from a massive horde of monsters, achieving great success! Meanwhile, back at his family’s home, a wicked scheme is underway…!? (Source: AlphaPolis, translated)
