First Appearance SAO: Other Side

Daisuke Shiba (しばだいすけ, Shiba Daisuke?), known as Imperius (インペリウス, Inperiusu?) in SAO and ALO, is the Protagonist of Sword Art Online: Other Side.

He was one of the 10,000 players who were trapped inside Sword Art Online, and eventually became the leader of the Golden Knights. He was one of the top players in the game, due to having the highest STR and the unique weapon known as the King's Legacy.


Real World / Sword Art Online Avatar

Imperius' avatar at the beginning of the game was best descriped as "tall, dark and handsome", looking a few years older than his real-life appearance and slightly taller.

During Kayaba Akihiko's tutorial, all player avatars were changed to reflect their real life appearances. After this change, Imperius' avatar had shaggy dark brown hair and piercing blue eyes, and was his regular height. He had a young looking face, making people believe he was younger than he actually was.

Imperius' first set of armor was dark blue with silver accents, and was extremely heavy and bulky, making him appear much larger and more intimidating. The helmet completely covered his face, obscuring his features. The armor also had an ability that slowly increased his STR attribute while he wore it, with the downside that he couldn't put any skill points into his AGI attribute and was slowed down significantly.

After he obtained the King's Legacy, Imperius switched to a much lighter suit of armor, which was a muted gold and black, and didn't have a helmet.

ALfheim Online Avatar

Imperius' appearance in ALO was incredibly similar to his appearance in SAO, due to it being converted from his old avatar using The Seed. Due to him now being a Salamander, his hair is a brownish-red color, and his armor is red with muted gold accents.


Born on November 17, 2004, Daisuke Shiba was one of the 10,000 people trapped in SAO on November 6, 2022, just eleven days before his 17th birthday. The moment that Akihiko Kayaba's tutorial ended, Imperius immediately went to search for his older brother Xenith, and his best friends Eiko and Barton, and the four of them worked together to level up as quickly as possible. After some time, Imperius split from the group when he felt he was falling too far behind.

Several months later, on March 12, 2023, Imperius had finally reached level 34, and had a very high STR after using his Titan Armor. He was one of the main Clearers who defeated the 12th Floor boss a few days later.

On May 22, 2023, Imperius met up with his original party, who had now formed the Golden Knights guild. After a fight with Barton, who was their leader, ended in a stalemate, he left his friends to continue leveling up.

On June 3rd, 2023, Xenith approached Imperius and challenged him to a duel, stating that if he won, Imperius would join the Golden Knights. Xenith won due to Imperius' armor being too heavy to counter Xeniths high AGI.

On January 19, 2024, Imperius, Xenith, Barton and Eiko fought the Tyrant Dragon Vasilias, with Imperius landing the final blow. Imperius was rewarded with the King's Legacy.
