Phenomenon

Natsu and Gray have been rivals since they were children, and it tends to cause lots of property damage. At his wits end, Makarov assigns them a mission in an attempt to make them bond. It goes well until a strange anomaly similar to that which once drug people to Edolas yanks them through a rift in space time, leaving them to fend for themselves in a nightmare world.

Now they must all deal with the consequences.
