The Arseid Style (アルゼイド流 Arseid Ryuu?) is a swordsmanship style unique to the Arseid viscount family. It was first introduced in the The Legend of Heroes: Trails of Cold Steel tetralogy, with Viscount Victor S. Arseid as the current master with his daughter being his successor.
Originated from the Eisenritter knights, led by St. Lianne Sandlot since the War of the Lions. The style became fairly renowned for generations to present time as it fully supported Emperor Dreichels Reise Arnor into winning the war. Now it remains in present time in Legram where the Arseid household functions as the dojo.
Using the Greatsword as the foundation weapon, the style focuses on offense and defensive maneuvers while honing on strength both physical and inner. Despite the disadvantage from the weapon's size, the weight should be balanced by the practitioner's physique and awareness to his surroundings through constant training.
