Fairy Tail: Return of the Heavens

[Complex], [Fairy Tail], [Demon Slayer], [Black Four]... Lorne, a young man from another world who traveled through Fairy Tail, failed to learn magic for seven years and became an ordinary person in the guild. Until the silent dimensional power in his body threw him into a world where evil spirits were rampant. The breath of ice merged with magic power, and the ghost-killing skills turned into ice magic. And this was just the beginning. The power of dimensions erupted from time to time, throwing him into the heavens and worlds again and again: The ice magic transformed by demon slayer, the time and space magic brought by the Black Four Magic Books, the magical mysteries of domineering entanglement in the pirate world, the fusion of imperial equipment in the red slayer world, the Zanpakutō roaring in the hands of the magician... Every time he returns, he only returns to the Fairy Tail world for a moment, but he rises with new power! When the powers of all worlds converge in the world of Fairy Tail, Lorne will eventually write the legend of the "Dimensional Mage"—— "My magic is the sum of the infinite worlds!"
