The Last Blade
In "The Last Blade 2", Gaisei is still deceased. However, an unknown force of evil resurrects him and drives the now-undead warrior insane. Additionally, he manages to combine the legendary powers of Suzaku, Seiryuu, Byakko and Genbu into his being, making him much more powerful than before. The now godlike warrior roams the lands and is called “Kouryu”, the Yellow Dragon.
