Marin

Marin is a girl who saves Link and falls in love with him.

Link's Awakening
As the game begins, Link awakens in Marin's house after washing ashore on Koholint Island. Link mistakes Marin for Princess Zelda due to the fact that the two are remarkably similar (stated by the Link's Awakening manual). She hates it when Link steals things and tends to yell a bit at him. But as the game advances, she starts showing much fondness for Link, and soon develops a bit of a crush on him.

As the game progresses, Marin teaches Link his first Ocarina song, "The Ballad of the Wind Fish", a song that made a reappearance in Majora's Mask. At one point, she also follows Link about in order to help wake a sleeping walrus. This part of the game is notable for comical moments such as when the two fall down a well and when she grabs the operator of the trendy game using his mechanical crane. Later, she is kidnapped by monsters and stranded on a broken bridge. Link saves her using his hookshot.

In a secret reward ending, if a player completes the game without losing a life or stealing from the hardware store, Marin is granted her wish and becomes a seagull so that she can fly to distant lands and sing to bring joy to others.

Personality
Marin's personality has been closely linked to that of Zelda's. Both love to sing, have a strong moral justice, and both look exactly alike.

Similar Characters
Other characters who are somewhat simlair to Marin are Malon from Ocarina of Time (in terms of appearance, name and singing abilities, Malon may have been based on Marin) and Aryll from  The Wind Waker with her affinity towards seagulls
