This world there are monsters which are called pokemon. After the period of war human and pokemon began to coexist and the creation of pokeball which leads humanity to new era.Humans thought with the new creation it can lead to top of the food chain and control the world but soon after that they realize how arrogant and stupid they were
Not only pokemon were very dangerous there are also some ultra divine beast known as legendary pokemons and power of those beings cannot be measure by human means. They will show up, whenever the balance in the ecosystem is broken
Under the power humanity have no other choice but to yield
After this period some powerful families throughout the world decided together to form the Pokemon Alliance to control the pokemon trainers. They make peace with the legendary pokemons and with the recognition of these pokemons Alliance unite regions after region.
As of now there 6 region under the Alliance and not long in the futur even the remote region Alola region has no choice to compromise and go under the Alliance. Under Alliance with the help of well known Professor such as Oak the technology have soared to the next level and the rapid growth of humanity began starting from Kanto region till the alola region. But there is a rumor that some say Alola region is not the end, after Alola there is also another region that nobody knows and their technology is very unique. (But there will not be any Galar region pokemon or gigantamax forms)
Alliance also make the rule to not abuse or ill treat any pokemon to avoid the anger of legendary pokemons. Killing pokemon or mass catching pokemon is consider as taboo and if caught you will be jailed for life. This help some family to control certian pokemon species like Jenny family which control all growlithe. Without their consent no one can buy or caught growlithe species.
Being a pokemon trainer is a very dangerous and costly job but a lot of people still choose to do it because the reward it gives is worth the risk. But without power and support of great family it is nearly impossible to become powerful so a lot of people die everyday in the process or catching and training pokemon.
So alliance start to give starter pokemon and open academy to teach students. Only after you finish intermediate academy at the age of 14-15 you has the right to own a pokemon. After the age of 15 people can either choose to go out for an adventure and rely on theirselves to become powerful or choose to go to a top rank academy to directly become and elite trainer and join Alliance. Joining Alliance will give many benefits such as free health care and discount prices. But these are mainly for the nobles and normal family cannot afford to go to such academies because the entrance exam is very difficult and only a small amount of all the appliers is accepted.
If normal family want to be pokemon trainer the only option is to catch bug type pokemon which the growth rate is fast and grass pokemon which are mild or some common normal pokemon.
Breeding pokemon is very expensive process and many pokemon have a very large appetite and they need very nutritious pokemon food if not they potential will start to degrade.If you want to improve potential there is also a pokeblock but even the worst one is 10 times more expensive than the pokefood. A normal pokeblock for a meal is sometimes equal the a year worth salary of some family. Even most nobles cannot afford top rank pokeblock. Nevertheless there are some commoners in those academies as the saying goes 'there are no weak pokemon only weak trainers' so some who are excel in training bugs and grass type still has a chance.
That is why although there are many trainers the advance trainers that with pokemon above lvl 30 is comprised only of 10 percent of total population. Due to these situations the emergence of criminal organizations in various region is inevitable. There are also pokemon poachers which are call hunters guild as well as many black market. The last two thing are also beneficial to Alliance so they turn a blind eye and in some city it is the alliance family that control the black market.
Among those organizations the most powerful and notorious is Team Rocket. They control almost one third of the dark side of all the regions which include most powerful Kanto region where the Alliance started and Jonto region cousin of Kanto region. With the leadership of new leader their growth rate is even faster than that of Alliance. Some say that their new leader is very powerful and ambitious and aim to control the world in the place of Alliance. With that the confrontation of these two become more and more serious.
In Kanto region, northeast area of vermillion city, a boy is siting in the bench day dreaming of something and in front of him, some kids are playing tags and the laughter can be heard throughout the orphanage.
