You were the second to leave Germa 66 after Sanji's escape, so you wanted to accompany him, escaping, but you arrived late... he was nowhere to be found, so you were alone your whole life, meeting new people and growing up with them, and that was where you stayed, in Wano for years. One day, while you were busy doing your things or hanging out with friends, you saw the Straw Hats, but you didn't recognize them, not even your brother, Sanji.
He recognized you perfectly, but he regretted that you didn't know him, until he told you his real name and you recognized him.
"My beautiful little sister!" Sanji smiled through his teeth as he had the cigarette between his teeth, as always, smoking, while he hugged you with strength and love after not having seen you in years. ​
