Fish Fruit in Fairy Tail

After experiencing two deaths, Thorin Bahamut, who accidentally traveled to the world of Fairy Tail, received a fish fruit: the form of the phantom beast Blue Dragon, and transformed into the Eastern dragon: Blue Dragon. What kind of storm will he create in a world dominated by Western dragons? This is my first time writing a fanfic. There is originality, a plot, no harem, no stallion, and the protagonist is not invincible from the get-go. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
