Story

Set in a future where rising sea levels caused by global warming have flooded much of the planet, humanity now inhabits floating cities. Maia Mizuki, a 15-year-old orphan and top student, dreams of joining the prestigious Ocean Agency, a branch of the world government. Despite her strong academic record, Maia unexpectedly fails the entrance examination. Following this setback, she endures eviction, theft, hostage situations, and injury before being saved by Rena and Shizuka of Nereids, an unconventional mercenary group offering various services. With limited alternatives, Maia becomes a member of Nereids, undertaking assignments ranging from apprehending criminals to miscellaneous tasks.

The name "Daphne" derives from Maia’s grandfather’s final words and a laurel tree connected to a time capsule buried in Elpida, an underwater city lost more than a century ago. The subtitle "Brilliant Blue" symbolizes the oceanic world dominated by water with sparse islands and floating settlements. Midway through the series, Maia sets out on a mission to recover this hidden capsule.

A recurring phrase taught to Maia by her grandfather emphasizes perseverance through hardship: "A tree that is planted by water will produce fruit in due season..." This echoes the sentiment found in Psalm 1:3.

The manga serves as a prequel taking place one hundred years earlier when humanity lived beneath the sea in Greek-named cities such as Elpida (meaning "hope"). Its protagonist is Ai Mayuzumi, who is Millie’s great-grandmother.
