SSS Order (left) vs. Star King's Insignia (right)
In Accel World Light Novel Volume 21, Kuroyukihime uses a mysterious program called the SSS Order. Given to her by Graphite Edge, this program is capable of hacking anything except for the Brain Burst systems themselves.
The icon of the SSS Order takes on the appearance of two parallel vertical swords surrounded by a ring of flowers. This icon is almost identical to Sword Art Online’s “Star King’s Insignia”. In fact, the design of Kirito’s “Night Sky Sword” and Asuna’s “Radiant Light” can clearly be seen on the SSS Order.
A comparison of the two symbols can be seen on the right, with the SSS Order on the left and the Star King’s Insignia on the right.
