In Soul Calibur 5 for the PS3 and Xbox 360, you can unlock the Soul of Devil Jin fighting style (from the Tekken series) that can only be used when creating custom characters.
To unlock the Soul of Devil Jin fighting style, you need to beat Harada in either Quick Battle mode or Legendary Souls mode.
You will unlock Legendary Souls mode after you beat the Story mode with any character.
