Black crystals can be found during the Seiryu the Azure Serpent fight. They are found on the shackles that hold it down. They must all be destroyed in order to temporarily free Seiryu and end the fight. They can only be destroyed once the player has jumped onto the shackles after dealing enough damage to Seiryu beforehand.
