After Trafalgar Law and Straw Hat Monkey D. Luffy defeated Donquixote Doflamingo, they prepared to join forces against one of the Four Emperors, Kaido of the Beasts. But they were ambushed by the captains under Kaido. The difference in strength was simply too great. In their final battle, Law managed to awaken the power of the Op-Op Fruit, but in the end, he was struck into the sea and met his demise...
When he opened his eyes again, he found himself in a child's body. That would have been bad enough, but why were there aliens? And who was this cute long-haired girl in front of him, calling herself "Onii-chan"? He remembered her name was Yuuki Mikan...
Everything began anew when he met a certain super-genius alien girl, and so began his true rise to power once more!
