In 2016, Fox opened up a sister site called "Fox Eye ABYSS", that exclusively covers the developer's R-15/18+ games, starting with BLUE GUARDIAN: Margaret. He tends to hire and collaborate with musicians, voice actors and (sometimes) English translators from other groups and parties to cover the rest of the game's development. Owing to its niche, this circle is quite small, as nearly all of the work that is put into Fox Eye's games, such as programming, debugging, character design, stage design, script writing, sound effects, and website development, are all done by Fox himself. It is not uncommon for some fans to even mistakenly view some of these games as H-Games due to these factors (however, the circle does have near-genuine examples). As such, despite the relatively-clean, all-ages material that can be seen in their previews and their developer's website, most of Fox Eye's games can be seen as Not Safe for Work due to the large drowning focus of the developer giving off fetish vibes, among other NSFW Fanservice tropes in certain games such as Stripperiffic and Clothing Damage. The underwater/drowning theme of this circle owes itself to its main designer's huge fascination for it, as Fox seeks to portray the beauty of girls in all sorts of safe and dangerous underwater scenarios, while also building a gathering of fans that share his same thoughts. The circle has covered several different Video Game Genres with the Oxygen Meter as their central and unified mechanic in mind. Thus, the main focus and challenge of the games is to learn the required timing for when and how to travel underwater, and answering the call to resurface for air.

Their niche is developing underwater fantasy games with a large emphasis on maintaining an Oxygen Meter in order to complete their games without letting their (usually female) protagonists drown. "Fox Eye" is a Doujin Soft circle that was established in 2008 and lead by a designer who codenames himself "Fox".
