输出：

Assuming the world in the One Piece universe is round, then there is not really a beginning or an end of the Grand Line.

The Straw Hats started out from the first half and are now sailing across the second half.

Wouldn't it have been quicker to set sail in the opposite direction from where they started?
In the middle of The Dark Tournament, Yusuke Urameshi gets to fully inherit Genkai's power of the Spirit Wave by absorbing a ball of energy from her.

However, this process turns into an excruciating trial for Yusuke, almost killing him, and keeping him doubled over in extreme pain for a long period of time, so much so that his Spirit Animal, Poo, is also in pain and flies to him to try to help.

My question is, why is it such a painful procedure to learn and absorb this power?
In Sora no Otoshimono, Ikaros carries around a watermelon like a pet and likes watermelons and pretty much anything else round.  At one point she even has a watermelon garden and attacks all the bugs that get near the melons.

What's the significance of the watermelon and why does she carry one around?
