Azure Sea Orca

Azure Orca (蒼海のオルカ, Sōkai no Oruka) is one of the Three Azure Knights.

Appearance
Azure Orca appears as a stitched-together version of Orca, with more armor.

Personality
Azure Orca appears to have little to no personality. He goes about his job of defending the system, seemingly specializing in destroying AIDA. Azure Orca has no speaking lines, but speaks normally when using an Art. He also speaks (unvoiced) in corrupted text after receiving an item. Azure Orca is the only one of the Knights to say Haseo's name in his limited dialogue.

.hack//G.U. Games
Haseo first encounters Azure Balmung and Azure Orca on the AIDA mirror server. Just as the transfer command is about to send Haseo back to the original server, a huge AIDA appears and attacks him. He is saved by the two Azure Knights, who kill the AIDA with one strike, something supposedly impossible without avatars. Haseo then notices a coffin floating alongside them, containing Azure Kite. Right as he realizes his nemesis still exists, the transfer protocol resumes and Haseo is returned to the CC Corporation server.

Later, Azure Orca and Azure Balmung seemingly appear in the Arena, assisting an AIDA-infected Sirius. However, while fighting Sirius, Haseo's team notices that the two mysterious players are "ghosts", phasing completely through any attacks. Once they defeat Sirius and the Helen-type AIDA inside him however, the real Azure Balmung and Azure Orca arrive, killing their imposters, who dissolve into black spots. It is later deduced that the fake Azures were mirages created by Atoli's Epitaph, which the AIDA inside Sirius had stolen. After this encounter, Haseo questions if he was wrong about "Tri-Edge", who seems to be an ally, not an enemy.

Later, the Azure Knights briefly appear in the aftermath of the Moon Tree incident, and Azure Kite is freed of his coffin. Finally, the Knights confront Ovan in front of a Sign leading to the Keel Mountains of Briona Gideon, and are seemingly defeated, though their regeneration ability suggests they are not gone for good.

The Knights quickly heal however, and finish off Sakaki after he falls through Avatar Space into an Outer Dungeon. Later, when Haseo, Yata, and Aina attempt to contact Aura at Hulle Granz Cathedral, the Knights appear and intervene. However, after a brief skirmish in which Haseo discovers that Azure Kite is more or less invincible, Aura inhabits Aina's PC and orders the knights to stand down. After clearing the game, Aura decides to give the Knights to Haseo.
