In a peaceful little village in the mountains of France, lives a boy who until this point had lived his life in relative peace, playing with his non-existent friends. That morning started the same for Fran as every other morning the only difference was the bad feeling that had settled within Frans stomach, the green haired boy endeavored to ignore the feeling and see what would come of it.
Fran left his house and set about walking to the river that was settled above the village. Just as he was about to reach the river Fran gasped and fell to the ground in pain as memories of things that he had never experienced, but were undeniably his streamed into his mind. Once the stream of memories ended Fran blinked from his spot on the ground as he tried to comprehend what had happened, now if Fran had been the older Fran then what happened next would have most likely gone like this - "Stupid Pineapple sensei, this is probably all your fault" Fran said neutrally under his breath as he stood " hmmmm but what to do what to do, I could go to Japan and met up with Pineapple sensei, or go to Italy and see the fake prince sampi, decisions, decisions" Fran might have said to himself - but of course this was not the older Fran that had been through so much but a young boy who had yet to see the terrors of the world outside of his village. The one thing that the Arcobaleno forgotten when sending back memorys is that not everyone had the experience to stay completely sane after experiencing the strain of gaining the memorys of 10 years of themselves seeing nothing but death, these memories brought with them only fear for Fran.
*time skip* _
Fran was sitting peacefully on a rock now surrounded by a group of 'fairies', and 'tooth decaying fungus' and so he quickly does an exorcism dance.
After explaining to them that he had lost his recent memories after hitting his head, he desided to go with the 'pineapple head fairy' who was going to teach him to be super epic cool, ' hopefully' Fran thinks 'they make better food then Grama'.
Of course the funny thing about amnesia is that the more time spent around the things you have forgotten the more likely that you will remember what you had forgotten.
