It's as the title says. This is a challenge to whoever is willing to take it up.
Harry jumps through the veil after he becomes the master of death, and ends in the eyeshield 21 world. Reborn as Sena, only with green eyes. It doesn't have to follow the story-line to a T, but it has to follow it for the most part.
But the MOST important part is that this must be a Gaou x Sena (Harry), there just aren't enough Gaou fanfic's.
If you wan't this challange, PM me or Review.
P.S you can change the Rating K to whatever.
