Secret societies that protect the human race from monsters are a common plot device in video games, more often than not requiring you to harness superhuman abilities to keep the world safe. Operation Abyss New Tokyo Legacy has taken this concept, and placed it within a fictional modern day Japan. After waking up in a sewer with no idea how you arrived there, you are rescued by the XSith Squad, an elite group of individuals that exterminate monsters known as Variants to protect the world from total destruction.
After being enlisted in the group yourself by the leader Captain Alice, you are trained in the arts of surveillance and using a power known as Code Rise to inherit superhuman abilities such as enhanced strength, flight and magical spells. Although you are a part of the organisation, you also do attend the high school in which the XSith squad is based, although you never actually attend any lessons.
