The second PV update of the One Piece theater version of "RED", the identity of the mysterious girl Uta is revealed, is the daughter of the "red-haired" Shanks of the Four Emperors, but I don't know if it is the daughter of the redhead. Although half of Uta's hair is red, many netizens still believe that Uta is most likely a red-haired righteous woman. Redheads are charismatic and like to wander, and it is normal to have little girls who worship him and recognize him as their father.
Uta is the "Singer of the World" who is crazy all over the world, and her voice seems to come from another dimension. In the trailer, many notes appear in the picture of the weeping Uta. Robin's character card line "What does this stave mean", and the character card line "You guys seem to know the girl's abilities". Combined with so much information, Uta is the one who is capable.
So, what exactly is Uta's ability? Before the official announcement, it can only be guessed by limited information.
Uta's ability must have something to do with music, there's no doubt about it. The sound fruit already belongs, which is the supernova Apu. Uta is a singer, and what drives the world crazy is her singing voice, her abilities and her own voice. Given that One Piece's esper species are a bit "flooded", Uta may be an esper species, or it may be a superhuman song fruit or something.
Of course, it is not excluded that Uta is a non-vocal ability such as the fruit of faith and the fruit of charm.
As for the effect of Uta's abilities, it may be a kind of mental inducement or control. For example, through singing, people who hear her are very infatuated with her, and quickly become her fans. In the trailer, the cockscomb Head Bartolomeo can be seen with Uta's name printed on his face and a cuff printed with Uta on his left shoulder. Chicken Crown Head is a fanatical fan of Luffy, how can he be so obsessed with Uta?
The situation of the cockscomb head does not rule out that he worships Luffy in faith and Uta in music. However, it is not excluded that the chicken crown head was actually brainwashed by Uta's ability and became a die-hard fan of Uta. After all, the picture of the cock's crown head is accompanied by "his (red-haired) daughter doing this kind of thing." If, Uta's ability is really induced to control others.
Then, Uta's first public concert may be to brainwash the world, which will be a big event that affects the world.
