Sure tub, did you read the first two chapters though?
Be honest about it. You could go for a katana, not a rocket launcher though, it just doesnt fit in the story really well.
And don't write in slang, but in proper English please, at least try to do the best you can.

If the chapter is not good enough, we will delete it.
Write an introduction chapter for your character and post it when these the following 2 or 3 writers have posted theirs, it's nice that you want to join. Feel free to start writing. Good luck
