Lin Yuan, a modern social animal, accidentally traveled through time and was reborn as "Kai", an orphan from the slums of the Kanto area. He was bound to the [Shadow System] - he needed to accumulate "Shadow Energy" by absorbing negative emotions, defeating powerful enemies, and completing dark tasks to unlock forbidden skills and alienated Pokémon. At the beginning of the game, a different color (pure black) Bulbasaur is awakened. In order to survive, he gets involved in gang wars. He uses ruthless methods to tame the gangster's giant sting wasp, and gradually establishes a foothold in the underground world of Dead Leaf City.
