When Guo Yi was thrust into a modern metropolis where Pokémon seamlessly integrated into everyday society, he gained access to an extraordinary ability: the Master Trainer System. This unique power forged unbreakable bonds between his own Pokémon and those of his disciples—with each student's growth directly amplifying his creatures' strength. The more accomplished his pupils became, the mightier his team evolved. His first notable disciple was Su Qingxue, a nineteen-year-old Shanghai native and sole heir to the Azure Dragon Society's leader, Ye Qing. She wielded the legendary Power of Viridian, channeling the ruthless legacy of Team Rocket's commander, Giovanni. In this reality, Pokémon transcended battles. They served as wildfire suppressors, disaster response units, athletic competitors, and essential contributors across every professional sector. Guo Yi attracted an extraordinary roster of students: a country-born scholar embodying Professor Oak's wisdom, a lethal operative commanding Elite Four Karen's combat mastery, an athletic champion carrying Bea's tournament-winning determination, and an entertainment industry luminary reflecting Diantha's charisma. By the time years had passed, society uncovered an astonishing truth—nearly every influential leader across medicine, business, sports, entertainment, and governance had studied beneath a single mentor: Guo Yi.
