Barely surviving in a barrel after passing through a terrible whirlpool at sea, carefree Monkey D. Luffy ends up aboard a ship under attack by fearsome pirates. Despite being a naive-looking teenager, he is not to be underestimated. Unmatched in battle, Luffy is a pirate himself who resolutely pursues the coveted One Piece treasure and the King of the Pirates title that comes with it. The late King of the Pirates, Gol D. Roger, stirred up the world before his death by disclosing the whereabouts of his hoard of riches and daring everyone to obtain it. Ever since then, countless powerful pirates have sailed dangerous seas for the prized One Piece only to never return. Although Luffy lacks a crew and a proper ship, he is endowed with a superhuman ability and an unbreakable spirit that make him not only a formidable adversary but also an inspiration to many. As he faces numerous challenges with a big smile on his face, Luffy gathers one-of-a-kind companions to join him in his ambitious endeavor, together embracing perils and wonders on their once-in-a-lifetime adventure.

Tomorou Tenma possesses a uniquely strong e-Pulse—the energy created by human thoughts and emotions that powers egg-shaped AI devices named Sapotama. The world's everyday life relies on the assistance of Sapotamas, but the force of Tomorou's e-Pulse often causes glitches in them. One night, a strange creature calling itself Gekkoumon emerges from his device and insists on eating Tomorou's e-Pulse. Gekkoumon is a Digimon, a creature feeding on e-Pulse that was born from an error in Sapotamas. Some Digimon completely drain humans of their energy, leaving them in a comatose state known as Cold Heart. When Tomorou's older brother, Asuka, becomes a victim of this phenomenon, Tomorou vows to avenge him. Tomorou meets a group of Digimon-wielders called Glowing Dawn, who hunt down rogue Digimon for bounties. Their leader, Kyou Sawashiro, explains that there might still be hope for Asuka's recovery. Although Tomorou struggles to trust these strangers, he decides to join them, as he realizes that saving his brother may not be achievable on his own.
