It's possible that Sting, Laxus and Lucy could become brothers and sister. But does fate have other plans in store for them?
Laxus doesn't know Lucy that well what happens when they get stuck together. They will have to help each other to get out of there situation as they grow closer together. Not that good as summaries just read please.
This is when Black butler and Soul Eater cross. They all go to the Trancy ball getting captured by Alois Trancy. I dislike summarizing so just come try it out.
