Ittoki Sakuraba fails to understand why his mother, his uncle, and his childhood friend, Kousetsu, seem to take his security so seriously. Kousetsu constantly follows and observes him with no regard for his privacy, focusing only on keeping him safe every waking moment. But the consistent hounding starts making sense when an adorable second-year student at his high school, Satomi Tsubaki, asks Ittoki out on a date. Though initially innocent, Tsubaki's true intentions soon become apparent when Ittoki visits her house; she plans to assassinate him, and she is not alone. Surprisingly, the ones who come to his aid are his uncle and Kousetsu—donning their dark and deadly ninja attire.

In order to protect himself against this new threat, Ittoki must hone his skills at the only ninja academy remaining in Japan: the Kokuten Ninja Academy.

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.
