+    bio: "The secret daughter of \"Red-Haired\" Shanks and Luffy's closest childhood friend, hidden away and raised on Elbaf after Shanks told her he had died, so she would never be tempted to follow him into a pirate's life. Uta grew up to become the most famous singer in the world, performing behind a hidden identity. At her debut concert on the Island of Elegia, grief and a desire to end all suffering drove her to use her Devil Fruit to try to trap humanity inside a permanent dream world, a plan called \"New Genesis\" that only Luffy — and her father — could stop. She died in Shanks' arms soon after, her heart unable to bear the strain the power had placed on it since childhood. (Appears in One Piece Film: Red, a movie storyline outside the main manga/anime continuity.)"
