Daphne in the Brilliant Blue

In the future, the earth is mostly covered with water, but the several cities that do remain are flourishing. Maia Mizuki has been trying hard to achieve her dream of joining the Ocean Agency, a government organization. When she fails to be accepted and faces homelessness and hopelessness, a series of unfortunate happenings force her into a job with Neres, a security and investigation company that will also do almost anything else for enough money. It soon becomes obvious that no one “normal” works at Neres. Shizuka is a kind, tech-crazy young woman with a passion for food, Glora is a trigger-happy, money-loving tomboy, Yuu, a quiet, brooding woman is frighteningly deadly in combat, and Rena is the capable, alluring, unofficial leader of this particular Neres office. With Neres, Maia faces danger and crazy situations daily; it’s almost too much for her, but Maia is strong, and she does her best to hang on and make it through this unexpected turn her life has taken.
