Story
In the future, water has covered much of the Earth due to the effects of global warming, leaving the human race to live on neighboring floating cities. The orphaned Maia Mizuki, fifteen years of age, just graduated from middle school and has already applied for employment in the elite Ocean Agency, part of the futuristic world government. Only the best, most intelligent, and physically fit students are eligible for admission. Maia, the series' protagonist, is set to become one of the few.

But her ideal life quickly falls apart. To her disappointment, Maia unexpectedly fails her entrance exams despite her high grades. Making matters worse, she promptly gets evicted from her house, pick pocketed, taken hostage, then shot. She is "saved" by two women (Rena and Shizuka) that are part of an unorthodox help-for-hire organization called Nereids (inspired by the Greek mythological Nereids). With nowhere to go, Maia joins up with Nereids, taking jobs from capturing wanted criminals to chasing stray cats, often with unexpected results. Gloria and Yu later join up with Nereids.

"Daphne", Greek for "Laurel tree", in the title refers to the last words said by Maia's grandfather. "Brilliant Blue" refers to the fact that this is a world covered by water with almost no land. The world consists of vast oceans, a few islands, and floating cities. This subplot that starts midway into the series concerns Maia's journey to retrieve a time capsule of her past buried under a laurel tree in Elpida, an undersea city lost over a century ago.

In almost every episode, there is a recitation of a verse that Maia's grandfather taught her.  She and others say it whenever her life is difficult or in danger - "A tree that is planted by water will produce fruit in due season, its leaves will never wither...".  It is never identified as Psalm 1:3, "He is like a tree planted by streams of water, which yields its fruit in season and whose leaf does not wither.  Whatever he does prospers." (NIV)

The manga of the series is a prequel  that takes place a century ago when humans were forced to live undersea when the cities were Greek named. Elpida means "hope." Now they're Russian inspired, like Kamchatka. Ai Mayuzumi, Millie's great grandmother is the protagonist of the story.

Characters
 
 
 Maia is the protagonist of the series. She has lost all of her childhood memories, because as a child, Maia was put into a one year coma because of a car wreck. The cause of it was because while in the car with her parents, the controls malfunctioned. Her parents died. Waking up, she was introduced to a man claiming to be her grandfather. In episode 11, Maia tells the girls of Nereids her story of waking up from her coma. During the flashback, Maia asks her grandpa why whenever he smiles at her, he seems sad. At the end of the episode, she is looking at a picture of her grandfather then she asks, "What is it that you were keeping hidden from me, Grandpa." Although Maia is an excellent student she is rejected by the Ocean Agency, an elite paramilitary organization that is part of the futuristic world government. So instead Maia, broke and homeless, joins  Nereids, an unorthodox help-for-hire organization inspired by the Greek mythological Nereids. She is optimistic, hard working, and honest, yet a naive and shy cute girl-next-door. Maia is in search of her past and continues to do so while working with Nereids.
 
 
 Leader of the Nereids Kamchatka branch. Rena is capable, elegant, and cunning, although she can be cold at times. Although not the branch manager in title, she is the de facto leader and makes the decisions. She is cool and calculating and her sharp instincts enable her to know the weaknesses of other people. Rena has no moral qualms about seducing others for manipulation or for a weapon use. She is also frugal with money and deducts pay from salaries under even the slightest pretext.
 
 
 Busty and bespectacled with purple hair, Shizuka is a brilliant mechanic who grew up in an inner city district of Shibuya and knows many people there. She is known for her poor shooting aim and is friendly, casual, and trusting with a voracious appetite for food.
 
 
 Loud, spontaneous, tomboyish, and somewhat reckless with a ganguro style complexion, Gloria is a trigger-happy champion marksman and the weapons specialist with a grudge against Rena for deserting her on a past mission. She tends to stick to her guns and loves to shoot things up and she does not get along with Yū. Gloria loves money and bothers Rena about how much she owes her. She is the only character without a regular civilian outfit.
 
 
 Silent, brooding, nihilistic, and a loner, Yu is a ridiculously strong fighter and hand-to-hand combat specialist. She had her license revoked in the past for destroying private property and injuring several police officers (including Detective Yagi) and bystanders. She has a loyalty to Rena, but does not get along too well with Gloria, where comically they are usually paired up on assignments, and constantly hits her. Yu's interests include animals and travel.
 
 
 Maia's best friend from her Ocean Agency days who got accepted, despite having average grades. She and Maia had made a promise to work with each other.
 
 
 The inept branch manager of the Nereids Kamchatka branch. He gets pushed around by his female co-workers. Hanaoka has a wife and a daughter Yukari.

 Son of their mother's seventh husband.

She is a martial artist and also wants to find the treasure of Elpida, to which end she stole a submarine (which gets repeatedly confiscated by the Nereids and subsequently stolen again by the family). The submarine was named Agnes for their mother. Shizuka renamed it Yomogi-1.
