Honnōji Academy

Honnōji Academy (本能寺学園) is a high school located atop Honnō City and the primary setting of Kill la Kill. The city is divided into four levels of residential buildings that are delegated to each student and their families based on the student's Goku Uniform ranking. The higher the Star ranking, the more prestigious the standard of living, with No-Stars being delegated to the slums.

The entire city is ruled over by the dictatorship of the Student Council President, Satsuki Kiryūin, whose power is in actuality due to influence of her mother, Ragyō Kiryūin. Based on maps shown throughout the series, appears to be an artificial island in Tokyo Bay. In episode 24 end credits, Honnō City, along with Honnōji Academy, is later seen in the bottom of Tokyo Bay.

Final Defense Apparatus
The Honnōji Academy Final Defense Apparatus (Kangi Needed) is the final defense against Life Fibers. It was intended for use against the Original Life Fiber but was not used due to Ragyō having hijacked the entire school. The main Academy building serves as the body/head of the machine, and it moves via multiple attached segmented arms tipped with giant hands, which are normally the wall surrounding the academy.

The Defense System attacks by swatting at enemies with its huge arms and hands or grabbing nearby massive objects for use as improvised weapons. Its force are powerful enough to create massive crevices in the ground. It also boasts an impressive array of guns, which seem to attack any target that comes close to the Defense System. The System is apparently powered primarily via Life Fibers and requires at least one human with sufficient potential to serve as its power generator.

In episode 25, the System was hijacked by Rei Hōōmaru, who used Satsuki and Mako to power it and tried to seek revenge for Ragyō and Nui's death. However, the giant machine was destroyed by Ryūko and her Scissor Blades in its "Final Graduation Mode".
