Ayano Keiko

Silica (シリカ) is one of the 10,000 players who were trapped in «Sword Art Online». She's a dagger-wielding beast-tamer when she first appears in The Black Swordsman hunting in the Forest of Wandering. Her real name is Ayano Keiko (綾野珪子).

Background
In SAO, Silica became the first player to tame a Feathery Dragon, which she named Pina (the same name as her cat in the real world), despite SAO being the first VRMMO she's ever played. She is introduced as a character whose parties treat her as a mascot and she is immensely popular on the middle floors due to her pet, and her status as a one of the rare beast tamers. She eventually becomes arrogant which leads her to separate from her party in the middle of a hunt and gets her lost in the forest. Soon after, a fight at the forest was the cause of Pina's death and almost hers before she was saved by Kirito, who then helps her revive the dragon. She is in the youngest age group of SAO players that are still active. She usually stays away from the males, who tried to marry her despite the fact that she was only 13.

The Black Swordsman (Aincrad 35th Floor, February 2024)


After a dispute with Rosalia, Silica leaves the party in the middle of their hunt. She goes through the forest alone and is attacked by multiple «Drunken Apes». Her familiar takes a hit for Silica and dies but she is saved by Kirito as she resembled his sister. Kirito tells her about a way to resurrect Pina. Though it is outside her level range she resolves to go one day, but finds out she only has three days to do so. Kirito agrees to help her get there, so they set off and return to town. They end up staying in an inn in order to discuss their plans to retrieve the flower.

The next day, she sets off with Kirito to find the flower. Despite encountering a few monsters, they reach their goal but on their way back they're ambushed by Rosalia and members of the «Titan's Hand» guild. Kirito reveals his real motive, sending the Titan's Hand guild to prison, and dispatches them easily. They finally agree to meet again, but in the real world. In the process of getting the flower, she gained feelings for him, but once she realized his skills, she realized that they could never be together in the game and begins to see him as a big brother figure, but continues to have feelings for him. Later on it is revealed that Pina (her familiar) was revived.
