Does Gray die, forever? Cause in the manga it shows that he dies.

Spoiler much ?

Not sure what chapter you've read to but Gray is alive and in battle in the most recent chapter of the manga that I've read. So no, he's not dead :)

HEY!! ARE YOU TRYING TO BE A SPOILER!?! Besides Gray could never die, he's way to awesome for that

Pfft! Someone dying?....In FairyTail?...Sure man, whatever floats your goat. #SPOILERALERT

He dies for a little bit but then Ultear uses a spell to turn back time 1 minute but the spell took away all the years that she had lived
