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 led by a designer who codenames himself 'Fox'. The circle's logo as it's shown in Sacrifice Girl.
