The world is divided into two kingdoms: the Kingdom of White, which floats in the heavens and is ruled by their queen Iris, and the Kingdom of Black, which stands upon desolate land below and houses the King of Darkness as its ruler. As of late, forces of evil have amassed great power, posing a threat to the entire world. Being the main representative of the Light, it is Iris' duty to maintain the balance of the world and fight off the darkness in her kingdom. Meanwhile in the Kingdom of Black, rampaging monsters annihilate a certain boy's village, leaving him the sole survivor. As he grieves in hopelessness, an armored man named Skeer notices the child and comforts him. Soon after, Skeer recognizes the boy's potential to change the kingdom's status quo and makes him his heir before passing away. The boy then vows to become the Prince of Darkness—the one who will replace the King—to bring the world back to its rightful path. As Iris and Prince of Darkness each challenge the impending doom the world faces in their own respective ways, their destinies will converge with each other, and perhaps, their bond will decide the fate of the world.

It all started in Kaminoyama High School, when five best friends—Aoi Miyamori, Ema Yasuhara, Midori Imai, Shizuka Sakaki, and Misa Toudou—discovered their collective love for all things anime and formed the animation club. After making their first amateur anime together and showcasing it at the culture festival, the group vows to pursue careers in the industry, aiming to one day work together and create their own mainstream show. Two and a half years later, Aoi and Ema have managed to land jobs at the illustrious Musashino Animation production company. The others, however, are finding it difficult to get their dream jobs. Shizuka is feeling the weight of not being recognized as a capable voice actor, Misa has a secure yet unsatisfying career designing 3D models for a car company, and Midori is a university student intent on pursuing her dream as a story writer. These five girls will learn that the path to success is one with many diversions, but dreams can still be achieved through perseverance and a touch of eccentric creativity.

At Tootsuki Culinary Academy, a heated eight-on-eight Shokugeki known as the Régiment de Cuisine rages on between Central and the rebel forces led by Souma Yukihira and Erina Nakiri. Though they won a stunning perfect victory in the first bout, the rebels face an uphill battle ahead, as they must now face off against the rest of the Elite Ten Council. With the future of Tootsuki at stake, Souma and Erina must push far beyond the limits of their abilities, using everything they learned from their mentors and ultimately drawing from their experiences cooking together as friends.

A dark age of cooking befalls Tootsuki Culinary Academy. With the Elite Ten's devastating coup d'état, Azami Nakiri is now the director of the prestigious school. Students must now conform to Azami's ideology of true gourmet food and are forbidden to express creativity, or else face expulsion. However, Souma Yukihira and the members of the Polar Star Dormitory refuse to accept these changes. Aided by other rebellious first-years, including the tenth seat, Erina Nakiri, Souma and his allies band together to fight off supporters of Azami's regime. But corrupt instructors and the menacing Central organization stand in their way, and so they must work together, harder than ever before, to survive every underhanded plot designed to banish them from the school.
