Would anybody else like to share their manga ideas.?

I'm starting a manga series but i could use some inspiration, here's what I have so far though.

A young man (age 21) is on a flight headed for Tokyo after his years of mastering numerous fields and fighting styles during his time in america.He's seen by everyone as an amazing genius for his knowledge of world religeons and has shown to have proven numerous religeons wrong. Even made millions and gotten on talk shows and magazine covers... Yet for some reason he still feels that there's somthing missing. Almost like a missing piece of a puzzle. The man ponders and ponders when suddenly there is a strike of lightning and the plain is struck down. It's going down fast and the man knows that at this rate he will soon die.so, with his last words he says " if a god really does exist if you spare my life i shall do your bidding" suddenly time stops. A white winged angel appears and says that god has spared his life but in return he must fight for him In the upcoming holy war in witch the gods of all diffrent religeons will come together and the Winner shall be crowned the most powerfull god and saint for 2 millennium.... So what do you guys think?
