Had an idea for like an one piece fict LOL
(still an female reader tho :v) like what if the reader had an twin and the thing only noticeable about them is their horns like the reader has the black horn which is on the left and the twin has the white horn which is on their right , of course the readers powers is gonna be about dark magic bla bla and the twin is gonna be about light magic bla bla. And like when they were kids they were inseparable, While the twin adored and wanted to be a pirate the reader wanted to be an marine, but one knight the reader snuck out their house and went to spy on some marines to know what they're doing but saw a marine being cruel to a beggar and killed the beggar. While the reader was seeing all that the twin heard an explosion and woke up and got scared seeing their twin gone so they went to tell their parents but found out they died , so the twin ran away with their aunt and found out pirates had invaded their land and now hated pirates. While the reader hated marines because of she saw. And like idk they meet somewhere and fight each other because of what they saw. :3
