Well, if you checked my gallery, you'd notice that I have an One Piece OC and I make my own story about her so yes, I do like, story-writing especially.
Sounds very interesting, but I have to refuse ^^' I don't do these kind of stuff for free and I have my own hurries with my own doujin. I hope you find someone else to make it for you, tho! I'm looking forward to reading it
