Shiomaneki is a Japanese male author and illustrator known for creating erotic manga, a genre often referred to as hentai. The creator is credited as both the writer and artist for all of their published works.

Shiomaneki has produced numerous manga titles since at least 2010. Notable original manga works include Kouzen Waisetsu Kanojo and Toppatsusei Inkou Shoukougun from 2010, followed by Shoujo kara Shoujo e... in 2012, Himitsu no Hizumi in 2012, and Girls 2 Women in 2014. The 2011 manga Amanee! stands as Shiomaneki's most significant work in terms of adaptation history. This manga was serialized in Comic Tenma magazine, with chapters published from September 2011 to February 2013, and was later compiled into a single volume.

The anime MILF Assault Mode, known in Japanese as Amanee!: Tomodachinchi de Konna Koto ni Naru Nante!, is a direct adaptation of Shiomaneki's manga. Released as an original video animation on December 20, 2013, this adult hentai production was animated by Studio 1st and produced by Pashmina. The story follows a character named Ryouichi who visits a friend's house, only to become the focus of attention from the friend's aunt, Yui. In this production, Shiomaneki is officially credited as the original creator, with the anime being based on the same-name adult manga.

The creator's artistic identity centers exclusively on adult-themed manga and illustration, with all documented works falling within the hentai genre. Recurring themes in Shiomaneki's work typically involve mature scenarios and relationships, as evidenced by titles such as Sexy Therapy and Himitsu no Hizumi. Within the industry, Shiomaneki represents the numerous manga creators whose original works serve as source material for the niche market of adult anime OVAs, a common pathway for erotic manga to receive animated adaptations.
