Four Season Bladers

The Four Season Bladers are a group of four Legendary Bladers that act as a key, along with the Solar System Bladers, in order to defeat the God of Destruction, Nemesis, and prevent it from ruling the world. They were first revealed in The Bladers of the Four Seasons. However, Kenta Yumiya obtained the summer constellation Star Fragment from Ryuga making Flame Sagitterio C145S evolve into Flash Sagittario 230WD, after that Ryuga and L-Drago Destructor F:S disappear. Ryuga has shown to be alive in the Shogun Steel manga. In the anime version, his whereabouts is uncertain (some people state that Ryuga may have died while transfering his Star Fragment to Kenta).
