A teacher from our world died simply because of stress, as he lived his life as a simple man he accepted this death for he knows this is what he gets from pulling all those all nighters and stressing himself out. Thinking that it's the end for him.
Oh how simply wrong he was, because by an unknown reason he somehow got reincarnated in a place similar yet different to the Pokémon world. A world called Ambrosius, but with the same set of characters like in the pokemon world with some new faces here and there.
'This world is set in the time in which Professor Oak is but a child, and the timeline is more cruel because of the after effects of a war that included all region.'
