Shō Aikawa, born Noboru Aikawa on August 9, 1965, in Tokyo, is a Japanese screenwriter, novelist, and manga artist whose career spans from the early 1980s to the present day. He is known for his extensive work across both anime and live-action tokusatsu productions, often writing under various pseudonyms including Gorō Sanyō, Kurou Hazuki, and Fukyoushi Oyamada. While a significant portion of his extensive filmography involves adaptation work, Aikawa has also served as the original creator or co-creator for a number of anime series.

Among his original creations for television is the 1998 series Neo Ranga, for which he is credited as creator and also wrote the screenplay for all 48 episodes. He conceived the original concept for Hiwou War Chronicles, also known as Clockwork Fighters Hiwou's War, a 2000-2001 anime produced by studio Bones. In 2006, he created Ghost Slayers Ayashi, a historical fantasy series for which he also served as main writer. That same year, he is listed among several authors as an original concept creator for the series Simoun. Aikawa is also credited with the original concept for the 2002-2003 series Strange Steel Fairy Rouran.

His most prominent role as an original creator in the 2010s is Concrete Revolutio. The 2015 anime series, subtitled Superhuman Phantasmagoria, and its 2016 second season, The Last Song, are officially credited as an original work created by Bones and Shō Aikawa. For this project, he wrote the majority of the episodes and conceived the core premise. Director Seiji Mizushima explained that the series originated from conversations with Aikawa about the proliferation of hero characters in Japanese media from their shared childhood in the 1960s and 1970s.

Aikawa's approach to adaptation work is also a notable part of his profile. When serving as the main writer on adaptations of existing manga, he is known for implementing significant deviations from the original source material. His work on the 2003 version of Fullmetal Alchemist is a well-known example of this tendency. In addition to his anime work, Aikawa has been highly active in tokusatsu, serving as head writer on productions such as the Kamen Rider series, including Kamen Rider Blade and the first half of Kamen Rider Decade, as well as the Super Sentai series GoGo Sentai Boukenger.

Reflecting on his creative philosophy, Aikawa has described script writing as being akin to writing a diary, suggesting that a creator can only write about their present feelings and observations. For Concrete Revolutio, he explicitly drew upon his own childhood during the Showa era, blending his memories of hero shows with a technique he admired in American comic books like Marvels and The Dark Knight Returns, which interweave fictional heroes with real-world history. He stated that if the heroes depicted in fictional works contain reality, then writing about them is no different from writing about reality itself.
