After Unifying the Fairy Guilds, They Invaded the Parallel World

Emperor Cassius, who has ruled the Albert Empire for 400 years, decided to launch an expedition to the parallel world of Eslandon through the super-subspace magic Anima. The first to land were Erza, the leader of the Imperial Knights, Mirajane, the strongest executioner in the empire, and Wendy, the captain of the imperial medical team. Here, they were surprised to find—— Erza: "Tower of Paradise? I was actually a slave when I was a child?" Mirajane: "What? Lisanna is gone? I became a receptionist and a graphic model? Is this what an executioner should do?!" Wendy: "Grandilie disappeared? Did I grow up alone in the forest?" And the local people in this world—— Zeref: "Finally someone can kill me and save the world from the fear of the black dragon." Acnologia: "Don't take me with you if you are bragging. My dear Emperor, do you still need a mount?" His Majesty the Emperor himself said thus—— Cardiff: "I have been fighting all my life. It's time to enjoy it. Come on, let's play music and dance."
