Yu-Gi-Oh! CARD GAME THE CHRONICLES is a monthly short-anime series showcasing Official Card Game-original card themes. It is an expansion of the demo reel of the same name released the previous year.

Seven Japanese high school students enjoy international renown for their remarkable talents. One day, these friends survive a plane crash only to find themselves in the medieval fantasy world of Freyjagard, where two human races live side by side in a feudal society: the byuma, who have animal features and formidable strength, and the hyuma, who have a small chance of magical aptitude. After being rescued by the byuma Winona and her adopted elven daughter Lyrule, the group pledges to use their advanced skills and knowledge to pay back the people of Elm Village for their hospitality and find a way to return back home. Tsukasa Mikogami, the prime minister of Japan, acts as the leader of these young geniuses and organizes their efforts to intervene in Freyjagard and gather the information and resources necessary for achieving their goals. Believing that there is a connection between their current situation and an ancient legend about seven heroes from another world who defeated an evil dragon, Tsukasa directs the others to learn about the culture around them and search for any clues leading them back to Earth. But he also gives another instruction: to take it nice and easy, lest they ruin this world by giving it their all.

Nikola is just a village girl working at the inn...until the day dragons invade, and she meets Haga, a scholar of everything around him. He's a part of an elite society called "Seeker," created to address a series of maladies plaguing their usually peaceful world. But both Nikola and Haga have secrets they hide...ones that will change each other's very existence...

A 30-year-old man who dreams of becoming a wizard suddenly loses his life. Reincarnated in another world as a young child named Shion, he grows up alongside Marie, his dependable older sister who adores him. Shion eagerly anticipates using magical powers, but he discovers that the new world seemingly does not have any magic. He spends the ensuing years as a gloomy and dejected child until a mystical phenomenon at a nearby lake catches the siblings' attention and breathes life back into his magical dream. While experimenting on the peculiar light emanating from the water, Shion finally confirms that magical energy really exists. It may not be convenient for anything just yet, but Shion devotes his time to studying the anomaly, determined to uncover all the existing wonders in his quest to make magic.
