I said this before but if Law lost his sword he should have a fighting style similar to the doctor in YYH
Tho I highly doubt Oda not only takes Law's hat AND sword away from him. Those are huge merch sellers lol
not really, isolation is common with depression. I think Oda could tell a good story of the path Lufy could've taken post summit war with Kid and Law. Giving Law the resolution to get his crew back again right away is boring imo. He should have a small character arc to get there
