Setsu (Japanese: セツ) is a character in the 2019 video game Gnosia. They are a non-binary soldier who, along with 13 other characters, attempts to escape the threat of the Gnosia Plague, but finds themselves, alongside the player character, in a never-ending loop due to each possessing an entity called the Silver Key. This object wants to acquire knowledge, and will only end the loop once enough knowledge is acquired.
They were envisioned as a fierce and aggressive character who valued justice, though this ended up causing them to make clumsy decisions. Their creator, Toru Kawakatsu, found this cute, and despite consideration to tweak their aggression levels, they found a workaround to keep this without negatively impacting the gameplay experience. Setsu was generally well received, with critics praising and analyzing the depiction of Setsu as a non-binary character. They were ranked the number one best indie video game character in Dengeki's 2022 indie games award show.
