Tia

Tia, also known as the Other Goddess or other Premiere, is a game adaptation-original character in Sword Art Online: Hollow Realization. Like her sister Premiere, she is a Non-Player Character (NPC), born from the creation of Sword Art: Origin.

Appearance
Tia looks almost identical to Premiere, the only identifying difference between the twins being the absence of Premiere's small mole right under the corner of Tia's right eye. Like Premiere, Tia has blue eyes and short black hair, the latter of which turns silvery white after she initiates the events of the Great Separation.

Hollow Realization
The Other Goddess was first encountered wandering the streets by Kirito. Mistaken for Premiere, she was led outside the Town of Beginnings, quietly minding Kirito's attempts at conversation while they climbed a hill overlooking a vast expanse of land. As she stared into the distance, she listened to Kirito's speech on the endless possibilities provided by their world and his desire to experience all of them with everyone. At that moment, upon hearing disturbed laughter, they investigated the sound to find a player hallucinating under the effects of a digital drug. When the trance player was forcibly logged out by his AmuSphere, the Other Goddess stated she had no explanation for the phenomenon they had just witnessed.

After the defeat of the boss of the Jeweled Peak Lakes, the Other Goddess was encountered by Genesis, who was furious at the developers for hiding the real boss behind a decoy, and at Kirito's group for defeating it.

Later, the Other Goddess was spotted by Kirito, Klein, and Agil, who were grabbing a quick meal at a popular ramen restaurant. Mistaken for Premiere yet again, she was invited to join them. Accepting the offer, she found the food immensely enjoyable and was slightly confused when Kirito suggested having everyone else along to eat with them for the next time.
