Ryo Aoi, who was a member of the Kijin Sentai Legend Mirror and was a Blue Fenrir, was captured and brainwashed by the Yugoth Empire, and became an evil spearhead as the fallen angel of destruction Valnaga. Varnaga sets his sights on other squadron teams on Earth to gain more power. When Varnaga encounters the battle of Nova Sentai Ryuseiger, he takes the form of Blue Fenrir and joins them and approaches.

After sucking the spirits of the three warriors of Ryuseiger and gaining even more power, Vulnaga transforms into a terrifying messenger of destruction and despair...! [Female executive HAPPY END].
