Human Sealing Technology

Human Sealing Technology is a technology installed in some Duel Disks that allows winners of a Duel to seal the losers into cards. This technology is mainly used by Duel Warriors of Duel Academy and members of The Resistance. During the Invasion of Xyz Dimension, it is seen being used against the innocent civilians who have no ability to Duel.

Process
The user activates the function on his Duel Disk, which emits a purple light that covers and dissolves the loser. A blank card with an image of the dissolved victim is then released from the Duel Disk. If the target is unable to Duel, the user can seal them in a card right away without needing to duel.

This process seems to be irreversible by LID's technology (however they are able to disable this ability as Shay's Duel Disk can't use it anymore). Celina and Shay, who themselves used the technology, showed no attempt to release their LID's victims after they joined the Lancers, suggesting that not even regular members of Duel Academy and the Resistance have ability to undo it.

Due to the technology originating from Fusion Dimension, it glows purple in light. But Kite Tenjo somehow modified it to Light Blue.
