One of Tsuki's friends in Arcadia.
From as early as she remembers, she, her brother Kalari, and friend Tsuki, have been inseperable. Her childhood, although nearly over, bears nothing but happy memories for her.
Coming from a family where musical talent runs in the blood, Marea has a beautiful singing voice, which frequently gets used.
When, or possibly if, she ever grows up, she'd like to travel the world, entertaining people.
At the start of the story she is 16 years old. She is fairly good-looking, a surprising fact since the last few hundred years have conspired to make the people of the Alseid Plains hardy and tough rather than beautiful.
