Ace had just been killed and put in the ground but what Luffy didn't know was he wasn't dead he faked it. Garp told him to do so but even he was under the lye that he was dead and would never come back. Ace now had to dig his ass out of the ground (kill bill Sean with ace that's all it is). he climbs out of the dirt and walks off to his new life on the lamb . he stopped to think of where he would go and he started off to a village his little bro told him of the village that nami grew up in it seemed like a nice calm place and it didn't have a lot of visitors to see him so that's the place he was to go. But first he would stop by the village he and his brothers called home windmill village.
