It is a semi-mechanical dinodragon summoned from the past due to "Stride". Many parts of its body, including its limbs, are mechanized, and the organic parts of its body are mostly covered by exaggerated weapons. This wild warrior can be described as a weapon from head to toe.
It had been unleashing its vehemence in the future world, but it was hit by an experimental weapon of the enemy nation and was teleported to the past. In other words, although it is summoned from the past, it was born in the future.
In a battlefield of the past, the warriors of "Tachikaze" were excited seeing a mysterious warrior appear abruptly with armament they had never seen before. Hearing their warcries, "Archraider" understood the situation immediately, that it was thrown into a war, and the enemies of "Tachikaze" were its enemies.
Archraider was praised as the "Destruction Tyrant" for slaying its enemies by pursuing and attacking them relentlessly. Though the tyrant had defeated the nations that dared to stand against it many times, it was finally defeated by the King of Knights of the holy nation. Though United Sanctuary won the war, it suffered more casualties than Dragon Empire. The warrior who pointed its fangs towards the king until the moment it was defeated was immortalized in documents of both nations, of friends and of foes.
