Play as Han Myong
After Soul Edge becomes selectable, beat Arcade Mode using Hwang, then Seung Mina immediately afterward. There are conflicting reports whether you must see both endings for these characters or not.
Play as Soul Edge
To play as Soul Edge, beat Arcade Mode with each character, OR leave the game running for 20 hours. If you pause mid-game, this 'timer' will still continue to run.
