-Press the accelerator to the end and have a big adventure on the road of life!
-That's right! Throw away the brakes and review! The author might as well just throw it away, Aru!

Because of Altana's wonderful connection with Ether and Hydeline, in order to protect the new life of his close friend Takasugi Shinsuke who fought side by side (in fact, in order to end the incident and make him the bottom of the daily food chain), everyone from Gintama came to the world of Final Fantasy 14!
