The Kirijo Group conducted many experiments on Shadows. I was created to help contain them. I am Aigis, the 7th Generation Anti-Shadow Suppression Unit. My Persona is Athena. Ten years ago there was an incident. It resulted in the creation of Tartarus and the phenomena know as the Dark Hour. I was damaged in the aftermath and rendered inoperable for the past ten year. This last year my friends and I managed to put an end to both unnatural occurrences.
