Marina is the youngest admiral of Adela Navy, a trusted ally of Kanterbury kingdom.
She lost her ship, Irmina, along with her crew to the invaders the day Kanterbury fell. The agony of losing her crew made her leave the navy and start a one-woman crusade against the invaders.
Marina's fleet was known to be the best of Adela Navy. Her precise and quick directions allowed the fleet to release deadly barrage to any enemy. She is also well known for her powerful swordplay. Despite her small body, she wields swords almost as big as herself with incredible strength. With her signature hookshot, she can even throw ogres around.
She may look aloof and cold, but that doesn't mean she lacks passion. She's just selective when it comes to what she actually wants to focus on. In other words, don't expect any attention from her unless you can make yourself her priority.
