Bararaq Saiqa (雷光剣, Bararāku.Saika, Lightning Sword) is a Metal Vessel of Sinbad. It gets its power from Sinbad's Djinn, Baal. When Sinbad uses it, he draws lightning down from the sky. Once the lightning has been summoned and stored in the sword, it releases an enormous lightning blast, able to fill the sky with light.
- The name of this vessel is a corruption of the Arabic phrase صاعِقة بَرّاقة Ṣāeiqa(t) Barrāqa(t), meaning "Flashing Lightning".
