The Jade Dragons (unofficial) are Lie Ren's weapons of choice. They are a pair of twin pistols with axe like blades that Ren can use to channel his Aura.

Description
They appear to be a pair of green machine pistols with extended magazines and foldable blades that Ren can conceal up the loose sleeves of his top. When fired, they give off flashes of jade light. The blades are incredibly strong, and sharp enough to pierce through tough material, such as a Basilisk's scaly skin.

Like all pistol-caliber weapons, Jade Dragons have a fairly low muzzle velocity. This sometimes puts Ren at a disadvantage, as seen in his battle with the Basilisks. The relatively low-power projectiles lacked the power to penetrate the monsters' hides.

Like some weapons in the series, Ren is able to use his pistols as a conduit for his Aura. When used in this way, his strikes become stronger and he can fire his Aura as if it were bullets. However, stronger opponents don't seem to feel these attacks.

Trivia

 * The pistols bear some resemblance to the M6 series of pistols from Halo.
 * They vaguely resemble Haseo's Xth Form weapon DG-X in .hack//G.U. Vol.3 Redemption installment, although they blades are in different places and the gun design is completely different, with Haseo's weapon being based off of a revolver.
