All of the other confirmed awakenings make sense like this.
Luffys is obvious. Law is one of the world's most skilled doctors and him awakening op op is also obvious. Kid is all force and aggressively attaching himself to or driving away others, in his personality and also his devil fruit. Lucci is a bloodthirsty killer who has fun in the hunt. Kaku is the worlds most obsessed with giraffes man. Katakuri is tough, but soft, and has a sweet interior, and he always sticks to his family. They all line up perfectly with their devil fruits symbolism
