Fujisaki Aya

Ayako "Aya" Fujisaki is Saki Tenjouin's loyal and assisting friend. The bespectacled Aya is weak-willed and became associated with Saki after she and Rin Kujou protected her from bullies when they were children.

So far, Aya has served little purpose throughout the series besides following and supporting her Saki-sama, whom she glorifies and idolizes. She is essentially something of an extra to their group, and has never been seen without accompanying her friends.

Appearance
Aya has long blue hair and purple eyes which are rarely seen in the series through the  glasses  of her big round lenses.

Personality
The most know aspect of her pesonality is her acting all fan-girl around Saki who she looks up to and cares for the most in her life. She is also one of the few girls who don't have any romatic feelings towards Rito, insted most of her admiration goes to Saki and naturaly hates his perverted accidents, especialy if it's towards her or Rin and most of Saki.

History
As a child, Aya was always bullied by boys until Saki (along with Rin) stood up to them and protected her from them, ever since that day Aya has always followed her and looked up to her with great respect.

Powers and abilities
Dispite her age, she is seen to be capable of driving and working heavy machinery like a crane. Although this was only seen in the anime, episode 5.

Saki Tenjouin
Aya respects and cares for Saki a lot, they are also realy close friends. As a child, she was often bullied and Saki protected her. So far, Aya has served little purpose throughout the series besides following and supporting her Saki-sama, whom she idolizes. She has never been seen without accompanying her friends, being something of an extra to their group. But Saki does care greatly for Aya as well as Rin, and wouldn't take the chance to study abroad if it meant leaving her friends.

Being weak-willed and nothing truly remarkable, Aya is perhaps one of the few evidences that the usually arrogant Saki Tenjouin has a good and kinder side towards lesser people.

Rin Kujou
 Even though  Aya  and  Rin  are always seen together with Saki and they both admire her, they don't exactly have any other thing in common and Aya shows more admiration to Saki than Rin does, as Rin often shows less emotion.

They first met each other when Saki and Rin saw Aya being bullied by a group of boys, and Saki insisted on helping her, while Rin just followed her. Since then, Aya has always followed them.

It's not quite known how Rin and Aya feel towards each other but they are realy good friends to each other, although they more often follow and pay attention to Saki, they have not often been seen interacting directly to each other without concerning  Saki.

Trivia
Aya made a cameo appearance along with Saki and Rin in Mayoi Neko Overrun! in ch 3 pg 24.
