Shinra-Kōketsu

"Satsuki's gonna get eaten by it. By my masterpiece."

- Nui Harime about Shinra-Kōketsu; Episode 19

Shinra-Kōketsu (神羅纐纈), sometimes translated as Omnisilk Kōketsu, is a massive garment produced by Nui Harime with the aid of mentally refitted Sewing Club members. Ragyō Kiryūin refers to it as "the ultimate Kamui". Ragyō eventually dons it to combat against Ryūko and Satsuki and their respective Kamui, Senketsu and Junketsu.

Appearance
Unlike Senketsu and Junketsu, which both were designed after sailor uniforms, Shinra-Kōketsu is designed after a traditional Japanese wedding dress. It is huge compared to the other Kamuis and it does not appear to have facial features, though a pair of eyes is visible during its production.

Trivia

 * The term 纐纈 (Kōketsu) refers to a technique of tie-dying commonly used in the Nara era of Japanese history.
