Just as the title says. Read to find out. Boku no Hero characters, original story and everything belong to Kohei Horikoshi. Fate series characters, original story and everything belong to TYPE-MOON. I only own the plot.

Meliodas and the Seven Deadly Sins have finally dealt with the Demon Race once and for all, and so decided to travel to Fiore for a vacation. It all seems okay... until they find themselves in front of Fairy Tail's strongest team who think they're still criminals and so try to catch them After some much needed 'explanation' (cough... beating the shit outta them, cough...), they come to a truce, automatically becoming friends. They party like crazy, test their strength against one another, even eradicate any threat as the greatest of allies Truly the world of Fiore and Britannia are odd and unique ones, but with a little mix of one another, the world just got a little crazier...
