Do Not Tread On Me Dragon On Steel

The Sea Breeze Ninjas' strength needs to be that of steel. His tensile strength is his strength before breaking. But, he needs the other attributes of steel; he needs to know when to be soft, he needs to know when to be ductile. He needs to be tough; showing resistant to corrosion and resistance to heat and to cold. Like steel, he needs to be malleable, weldable, and machinable. The point at which a Sea Breeze Ninja begins to permanently deform, this is his yield strength. The point at which he finally breaks is his ultimate yield strength, yet he must never break. - From The Chronicles of The Sea Breeze Ninjas
