Prolouge :

One day, on the land of Magnolia, Inside Lucy's room….

Natsu : nee ~ Lucy, let's go on a job, it's been weeks from our last job
Lucy : can't you wait for some time Natsu?, I'm almost done here.
Happy : what are you doing exactly Lucy?
Lucy : I found this awhile back at the guild's archive, It's supposed to bring back the time to whoever uses it for.
Natsu : eeehh, won't it be like that invisibility potion last time?
Lucy : It won't! I promise it won't end up like that one
Natsu : so sure eh? Happy, come here *murmur* *murmur*
Happy : Aye sir!
Natsu : Go Happy!

* Happy grabs the unfinished potion*

Lucy : Natsu, Happy, what do you think you'r-
Happy : ah! (Happy's magic wears off)

*Happy drops the potion at Lucy's head, a huge smoke appears*

Natsu : Lucy! Are you alright?!
Happy : Natsu, look!

*smoke disappears, Lucy appears to be the size of a child*

Lucy : pa…pa?
Natsu : EH?!
