Pokemon: A new world of adventures

A guy from our world ended up dying disastrously and ends up being used as a postman across the universes and ends up going to some Pokémon world. Now we follow your adventures in this world. This should be fun. (there is a gender-bender, this does not affect the MC at all; I will try to make an intelligent MC; there is no system; there will probably be no romance; this is the first time I write, so if possible leave comments and opinions so I can improve)
