I would spend it with kaidou it would be so fun, I would first ask kaidou to bench press an island (break it from its rocky and solid base at the bottom of the sea) and lift it kilometers above the surface of the sea.
Then I would fly with him to melt some islands...
Then I would ask him to use his tornadoes at sea to see how big a storm he would create.
And then I would ask to see what your lifting limit is with your flames and I would challenge you to lift an entire continent.
At the end of the day we would return to Onigashima, drink and go to the ring to watch Jack and Whos Who fight.
