Luffy was sitting down on the roof of his house.. He was staring at the stars.. He was trying to get some fresh air..

He was looking at the stars still.. He saw something flying in the air.. It kinda look like it was losing control and about to land in the ground

He got up and he carefully jumped off the roof to go investigate what was happening.. He saw it was gonna fall on the ground.. It looked like a space ship!? he ran as fast as he could to see what might happen
