Âge Seal (アージュ・シール Ājyu Shīru) is a Caster Magic that allows the user to control the properties of time.
This Magic gives the user the ability of controlling the time-space continuum, giving them the freedom of stopping all and every motion within their "world," suggesting that it is only accessible to the user of the Magic with the user being shown able to freely move around at will during its usage. To activate, the user clicks their teeth together which immediately postpones the time balance, as shown when Dimaria Yesta paused the time on battlefield. However, it appears that people who are also able to control the laws of space and time are able to penetrate the Magic, canceling it out to those who are affected. Also, there are certain people/magical figures who are to bypass this Magic, and it was implied they are able to move freely when the Magic has been activated.
