Lucina

A knight sworn to the Sama Kingdom, she was raised alone by her navy general father. At a young age, she was treated as a freak by others for her inability to control her innate magical powers. Though quiet and introverted, thanks to her father's training, her skills with the sword were rumored to eclipse even those of her dear friend Selena. Though she usually accepted Selena and her father's harsh words without a peep, on occasion she is said to have the mouth of a sailor. Her father started a civil war in Sama, in hopes to purge the navy of its corruption. Unbeknownst to them, he was playing into the hands of their rival kingdom. Lucina and Selena spared no effort in trying to rescue him from the ravages of war. However, he vanished leaving a mysterious letter--one with the whereabouts of the mother she assumed to be dead. Relying on a letter left by her father, she learned through her travels that her mother was the daughter of the ruler of all the fauna in the oceanic depths. She knew she could deny her divine marine powers no longer, instead unleashing them when the war against the gods began. Rushing back to her friend's side in her homeland, her awakened prowess with the sword was enough to drive them away from Selena in an instant. Having awakened her latent power over ocean creatures, Lucina countered the mage's hellfires with her water magic. Reunited with her beloved companions, Lucina pressed on, but the beaten mage called upon a forbidden ritual, engulfing the battlefield in a blazing inferno. It's said that Lucina threw herself into the flames without hesitation to save her companions. When she awoke, she realised that her body had changed into another form of existence. Then she let her eyes close again, and was surrounded by the soothing tranquility of the ocean floor and the warmth of her mother's love.
