One day, Tanjirou decides to go down to the local village to make a little money selling charcoal. On his way back, night falls, forcing Tanjirou to take shelter in the house of a strange man, who warns him of the existence of flesh-eating demons that lurk in the woods at night. When he finally arrives back home the next day, he is met with a horrifying sight—his whole family has been slaughtered. Worse still, the sole survivor is his sister Nezuko, who has been turned into a bloodthirsty demon.

On a new day in the Kanto region, Satoshi gets invited by Professor Yukinari Ookido over to Professor Sakuragi's lab-opening ceremony in Vermillion City. During the ceremonial speech, Professor Sakuragi receives an alert of a possibly rare Pokémon appearing in Vermillion City's harbor, leading Satoshi and the other trainers to rush to the area in hopes of finding the mysterious Pokémon. At the harbor, they find Lugia—a Legendary Pokémon—engaged in combat with other trainers. Noticing the other trainers' tactics, Satoshi has his partner, Pikachu, strike Lugia with a Thunderbolt attack. Unfazed, Lugia flees, but not before Satoshi determinedly leaps onto its back. To Satoshi's surprise, he meets another boy, Gou, who leapt onto Lugia's back as well. The two ride on Lugia's back as it brings them along on a bizarre adventure across the seas. As it lets the two back on the ground, Satoshi and Gou bid their farewells to Lugia and return to Sakuragi Institute. Impressed by Gou's findings and Satoshi's insight taken during their encounter, Sakuragi requests for the duo to be his new research partners. And so the duo's journey begins, traveling across multiple regions to meet many new Pokémon—including ones that have the ability to Gigantamax!
