The Lightning Tube is one of the Lightning Boxes that comprise Gokudera's Sistema C.A.I. It is the Lightning ammunition for the Flame Arrow and can be mixed with Storm Flames to make Flame Thunder. It differs from the other tubes because it is oval-shaped and it has four appendages.


  • Flame Thunder: Gokudera fires a beam of Storm and Lightning Flames from his Flame Arrow. The beam is strengthened by the Hardening factor of the Lightning Flames and armed with the Disintegration factor of the Storm Flames. Gokudera considers it the strongest attack available in the Sistema C.A.I.
