The Gyousei (ぎょうせい,Gyousei?, literally meaning "Morning Star") is one of the Two Legendary Cursed Sword of Hellpiea. It is the opposite of Static's inherited sword, Senhime. Out of the two, Gyousei is "the sword of destruction", while Senhime is "the sword of life." Gyousei has a mind of its own. It has been seen guiding Drazil, such as wanting to be drawn or giving him advice. And the same goes for Static's Senhime.
The Gyousei is considered to be the world's most beautiful sword and a valuable treasure of Hellpiea, despite its cursed legends. The sword is designed after a Cutlass naval sword, made out of Orichalcum, with an gold design guard and a somewhat elaborate hilt and a silver tassel at the end. The blade itself is Glistering Silver, with a curved edge
Gyousei Absorbs the life essence of foes and is Strengthened by the blood of deceit. Gyousei ha the ability to reform itself using the iron harvested from the blood of its victims. This regenerative process takes place almost instantaneously and is capable of bringing the weapon back to its original condition no matter how severe the damage is, from a simple chip or nick to a complete separation of over half the blade.
Gyousei shares a symbiotic relationship with its wielder, similar to that of the Jiten. Although it continually consumes the energy of its owner, its largest meals come from fights, wherein it absorbs the energy of the opposition instead. Such an ability allows Gyousei to literally slice through an opponent's techniques, in spite of whether the attack is a Devil Fruit has been transformed or not, and even prevent them from being performed by absorbing all of the necessary energy, before preparations can be completed. This is particularly useful when fighting Logia Devil Fruit Users, as Gyosei can quickly deplete their large Energy supplies as well as remove their Invunrability, illustrated when Sven D. Arks was reduced back to Normal. Gyousei is drawn to those with large Energy supplies, allowing it to be used as a quasi-sensor.
