Pirate: the King of the World Is Chasing Me

I, Lilith, belong to the D clan, Luffy's biological mother, and have lived for 800 years. He was tied to his side by Im, the King of the World, using the Symbiosis Fruit, and imprisoned in the underground palace. I thought this was it for the rest of my life - until I finished all the games. It was so boring that I ran away. Admiral? A look scares him away. Celestial Dragons? I'm going to take a detour. Straw Hats? That's my son's boat. What's wrong with me going on board to have a meal? But there is one trouble I can't get rid of—that yandere lolita with silver hair and red eyes, chasing me every day and shouting: "Lilith~Kiss me~" I pushed her face away: "Get out." She cried and came again the next day. It's been 800 years, isn't she tired? Wait... I seem to be a little used to it?
