 All of the Rangers have a number assigned to them. Chris Partn, the  leader of the Rangers, wears a 1, Lead Phoenix has a 3, Big Landman  is 5, Tillis is 6, Shou is 7 and Iria Klein is 8. It is never  revealed or otherwise explained why the number 2 isnt used, but 4  likely wasnt used because the game was originally Japanese, and the  Japanese kanji for 4 also means "death".
