Ok when I was younger I always bought shonen jumps. Well there was a preview for a new manga that was coming out. It was about a kid who was going to a new fighting school. His family had there own fighting style, the names of there techniques were the same as guns and stuff. He had brwon hair and it was kinda long. He wore a blue shirt. The guy that would be his rival had a white hair and had a fighting style with something to do with crosses. If anybody know what manga i'm talking about please let me know.
