I have carpal tunnel, so I need to rest for the year and in the meantime I will be working on writing.

I'm trying to think of a manga plot, one with superpowers and a power system as unique as One Piece. But it seems as though every idea is already taken. It should take place in either space or Earth with a global theme and the power system needs to be incorporated into the plot.

Can /ic/ help me think of a manga plot, at least something to begin with which I will be building up off of.

Many thanks.
