When former college student Kai (now Shinzō Tatsunaga) is mysteriously transported from Earth to Liyue Harbor during an intense Genshin Impact gaming session, he discovers he's been blessed with the extraordinary "Pokémon House System." Rather than pursuing a hero's journey, Shinzō establishes "The Pokémon House" in Liyue's bustling market district, becoming Teyvat's first Pokémon breeder, trainer, and merchant.
What follows is a heartwarming and comedic slice-of-life adventure as Shinzō introduces these mysterious creatures to a world of elemental magic and ancient gods. From teaching confused customers the difference between Pokémon and local wildlife, to hosting the first-ever Pokémon Tournament in Teyvat, Shinzō's days are filled with laughter, friendship, and the occasional chaotic Pokémon escape.
As his reputation grows, Shinzō gains the nicknames "Manager Shinzo" and "The Father of Pokémon" while entertaining visitors from across the seven nations. Regional Archons become fascinated customers, the Fatui express their interest in these strange creatures, and even the most reclusive adepti descend from their mountains to witness these extraordinary beings. With his shrewd business acumen, calm demeanor, and his six powerful Pokémon partners, Shinzō transforms from an ordinary college student into Teyvat's most influential merchant, spreading the joy of Pokémon across the continent one Poké Ball at a time.
