TV Special
Description
Aikurō Mikisugi teaches world history at Honnōji Academy, posing as a disheveled and lethargic middle-aged man. He sports messy blue hair, stubble, and large reflective sunglasses hiding his teal eyes. His slouched posture and consistently wrinkled attire—a loose white shirt, black tie, and black jeans—form his undercover identity, enabling discreet surveillance of student activities and intelligence gathering on the Kiryūin family's manipulation of Life Fibers. His true allegiance lies with the anti-Life Fiber resistance, Nudist Beach, where he holds the rank of Splendid Naked Officer.

Removing his sunglasses and sweeping back his hair transforms Mikisugi into a strikingly handsome, well-built young man. This shift often coincides with him flamboyantly removing his shirt, revealing nipples that emit a distinctive bright pink-purple glow—a signature trait of his Nudist Beach role. He operates the vehicle Naked Shooting Star and exhibits a strong aversion to the name "Dōtonbori Robo," insisting it be called "DTR" with uncharacteristic seriousness.

Mikisugi's personality shifts between his roles. As a teacher, he projects apathy and fatigue, speaking in a raspy, disinterested voice. As his true self, he becomes charismatic, confident, and deliberately provocative, frequently engaging in flirtatious behavior—especially toward Ryūko Matoi—through slow disrobing and suggestive remarks. Despite this flamboyance, he demonstrates deep commitment to combating Life Fibers and genuine concern for his allies. His scientific background in biology and medicine allows him to utilize acupuncture needles for paralysis, and he displays strategic acumen in coordinating Nudist Beach operations.

His history involves close collaboration with Isshin Matoi (later revealed as Sōichirō Kiryūin) on Life Fiber research. After Isshin's death, Mikisugi received instructions to deliver the kamui Senketsu to Isshin's daughter, Ryūko. He infiltrated Honnōji Academy as a teacher to fulfill this task and monitor Kiryūin activities. A personal tragedy motivates him: his fiancée, Kinue Kinagase, died during a Life Fiber experiment, connecting him to her brother and fellow Nudist Beach member, Tsumugu Kinagase. This shared loss establishes a bond of trust between them, though they occasionally disagree on tactics, particularly regarding Ryūko's potential threat as Senketsu's wearer.

Throughout events, Mikisugi guides Ryūko Matoi, directing her to Senketsu's location and providing covert support during her conflicts at Honnōji Academy. He monitors her synchronization with Senketsu, expressing concern over its rapid evolution. During the Tri-City School Raid Trip, he abandons his teacher disguise after Nudist Beach's Osaka base is compromised, publicly declaring his true identity and role. He later facilitates Ryūko's introduction to Nudist Beach headquarters, revealing the full extent of the Life Fiber threat. In the final conflict against Ragyō Kiryūin, he commands the Naked Sun ship and deploys its "Great Naked Blade" weapon against the Original Life Fiber. Following the resolution, he continues collaborating with Ryūko, Satsuki Kiryūin, and the former Elite Four under the restructured Nudist Beach.
