Not much is known on how long The AI has been in the Second Computer Room that the SSS or even Tachibana Kanade (Tenshi) were not aware of. According to him, he states he was "Simply obeying the rules" which means that he had been programmed (Most likely by The Programmer) to keep watch over the computers and watch how much love is in the Afterlife. When love began to manifest in the Afterlife, he most likely activated the Shadow Program to begin wiping out all the humans who are in the purgatorial world: the SSS.
The AI appears as a boy with short dark hair (mistaken to be a shade of dark blue) and dark blue eyes. He wears the Afterlife School's male school uniform.
The AI lacks human emotions, as he stated to Yuri in Episode 12 that he lacked any emotion of the thought of becoming God.
- It is unknown whether or not The AI is real or not. When Yuri shot at him, his dead body was not shown. Instead, it just showed a computer at where he was sitting.
