A man built his entire life around being useful to other people's adventures. Then he finds a girl in a meteor crater who calls him father, and suddenly he has to become the center of his own story. The show understands that fatherhood isn't about grand heroics, it's about showing up when someone needs you, even when you have no idea what you're doing. Leicester spends the whole series trying to keep a mysterious child safe in a world that keeps throwing impossible things at him, and by the end you realize that's the entire point, not a problem to solve.
In the trading hub of Ert'Aria, Leicester Maycraft lives a quiet life as an item engineer with the adventurer guild Oasis.

A stray meteor crashes through the building, revealing a hidden chamber where Leicester discovers a girl sleeping undisturbed. When she awakens, she calls him father, setting off a chain of mysteries that Leicester never asked for. Who is she? Where did she come from? Why does she claim kinship with him? As Leicester grapples with this impossible situation, the girl's arrival pulls him and his companions into a web of secrets tied to the meteor itself. What begins as a chance encounter transforms into genuine adventure, where Leicester must uncover the truth behind the girl's origins while protecting her from forces drawn to her mysterious power. The boundaries between his safe, methodical world and something far greater blur with each passing day.
