Also we've seen what Koushiro was doing 22 years ago
We saw Kuina being born in East blue 22 years ago when Oden was still in Wano trying to open the borders... So let's establish a supposed timeline
Koushiro was born in East blue
He came to wano for some reason and became a vagabond EVEN THOUGH HIS FATHER SET UP A VILLAGE IN EAST BLUE
He joined Oden's gang for a number of years
He left Wano more than 22 years ago and Joined/crrated ishin dojo in East blue got married and had kuina
He left East blue and his family AGAIN and was in Wano 20 years ago during the invasion of the beast pirates and fought Kaido
He left Wano AGAIN and went back to east blue to give his daughter añ inferiority complex and continue his Dojo
So
@ZoroGang this is about right?
