Sougetsuken

Sougetsuken (双月剣, Sougetsuken, Double Moon Swords) is the Household Vessel of Seishun Ri. It gains it's power from Hakuei Ren's Djinn, Paimon. The Vessel that it uses is Seishun's dual swords. Using Paimon's wind, Seishun's slashing power is increased, and all of his strikes remain and appear as the shape of a crescent moon. In the anime, Sougetsuken has also proven to be capable of expelling a gust of wind that is strong enough to knock back a group of soldiers.
