1 Rock Lee/Bell Cranel

Rock Lee diden't remember how he died, nor how he was reborn as Bell Cranel, he did however remember how his grandfather, his only family, trew him out into the streets.

Lee/Bell was down with a fever, so his grandpa had hired a doctor to treat him.

One diagnosis spell later, and they learned that A, the fever was caused by a cold and would go away on it's own, and B, Bell's body could not absorb high quality exelia.

exelia was a metafisical energy that came from monsters, an adventurer would kill monsters and absorb this exelia into their bodies. On it's own, exelia diden't do much, however there is where falna came in.

Falna was the blessing of a god, it used exelia to strenghen its user, it was the primary power system in this new world Lee found himself in, just like chakra was in the old one. The high quality kind was expecionaly importand, as it would allow one to level up.

Bell/Lee wondered if he was cursed. On his first life he got underdeveloped chakra coils, witch kept him from molding chakra, and in this new life, his body coulden't absorb high quality exelia to get out of level 1!

Lee/Bell had barely processed this coincidence before his grandpa kicked him out of the house in fury.

Rock Lee gave up the name "Bell Cranel" that day and moved to the woods, where he grew up.

Lee's routine in the woods was simple: wake up, hunt for food, eat, then train until he fell unconcious.

Lee trained hard so he cold prove everyone that he could be an adventurer, even with his handicap.

Several years passed like this. And one thing that Lee realised during this time, was that he still had his underdeveloped chakra coils from his last life.

Now, Lee had reincarnated into another body, meaning all his strenght and muscle memory were gone, but he did have the teachings of his youthfull sensei in his heart, so he could get back into shape.

Lee never realy liked his cripled chakra coils, but learning that they had not abandoned him in this new life sure was something.

And so, Lee trained. And once he was satisfied, he moved to orario, the city of adventurers.
