Why was drake even in wano in the first place.
Drake and his crew successfully made it into the New World. They stopped at a winter island and encountered "Iron Boy" Scotch, a subordinate of Kaidou. Scotch told Drake that the island is a favorite of the Emperor and is under his control. Drake questioned that if he were to attack Scotch, then he would get the attention of Kaidou, in which Scotch replied "yes". With this confirmed, Drake gladly activated his Devil Fruit and began his attack.[15]
