After the murder of her father, Ryuuko Matoi has been wandering the land in search of his killer. Following her only lead—the missing half of his invention, the Scissor Blade—she arrives at the prestigious Honnouji Academy, a high school unlike any other. The academy is ruled by the imposing and cold-hearted student council president Satsuki Kiryuuin alongside her powerful underlings, the Elite Four. In the school's brutally competitive hierarchy, Satsuki bestows upon those at the top special clothes called Goku Uniforms, which grant the wearer unique superhuman abilities. Thoroughly beaten in a fight against one of the students in uniform, Ryuuko retreats to her razed home where she stumbles across Senketsu, a rare and sentient Kamui, or God Clothes. After coming into contact with Ryuuko's blood, Senketsu awakens, latching onto her and providing her with immense power. Now, armed with Senketsu and the Scissor Blade, Ryuuko makes a stand against the Elite Four, hoping to reach Satsuki and uncover the culprit behind her father's murder once and for all.

Lucy is a special breed of human referred to as Diclonius, born with a short pair of horns and invisible telekinetic hands that lands her as a victim of inhumane scientific experimentation by the government. However, once circumstances present her an opportunity to escape, Lucy, corrupted by the confinement and torture, unleashes a torrent of bloodshed as she escapes her captors. During her breakout, she receives a crippling head injury that leaves her with a split personality: someone with the mentality of a harmless child possessing limited speech capacity. In this state of instability, she stumbles upon two college students, Kouta and his cousin Yuka, who unknowingly take an injured fugitive into their care, unaware of her murderous tendencies. This act of kindness will change their lives, as they soon find themselves dragged into the shadowy world of government secrecy and conspiracy.

The year is 2006, and the halls of Tokyo Prefectural Jujutsu High School echo with the endless bickering and intense debate between two inseparable best friends. Exuding unshakeable confidence, Satoru Gojou and Suguru Getou believe there is no challenge too great for young and powerful Special Grade sorcerers such as themselves. They are tasked with safely delivering a sensible girl named Riko Amanai to the entity whose existence is the very essence of the jujutsu world. However, the mission plunges them into an exhausting swirl of moral conflict that threatens to destroy the already feeble amity between sorcerers and ordinary humans. Twelve years later, students and sorcerers are the frontline defense against the rising number of high-level curses born from humans' negative emotions. As the entities grow in power, their self-awareness and ambition increase too. The curses unite for the common goal of eradicating humans and creating a world of only cursed energy users, led by a dangerous, ancient cursed spirit. To dispose of their greatest obstacle—the strongest sorcerer, Gojou—they orchestrate an attack at Shibuya Station on Halloween. Dividing into teams, the sorcerers enter the fight prepared to risk everything to protect the innocent and their own kind.
