The Aeon system (エイオンシステム) is a system built into Tio Plato's chest protector.
The Aeon system activates when Tio uses her orbal staff and orbal arts. The system's main functionalities are supporting Tio's instant art activation from her staff and high-speed throughput. Great aptitude is required to operate the Aeon system. Tio also uses the Aeon system playing Pomyo, allowing her to make enormous chains her usual opponent, Jona Sacred, is unable to overcome.
- In Ao no Kiseki, Chief Roberts points out the identical etymology of Epstein Foundation's Aeon system and the Thirteen Factories-developed Aion humanoid weapons. The Latin aeon and Ancient Greek aion both mean 'age' or 'eternity'.
