After the first season of the anime, Yai moves to Kingland and only appears sporadically throughout Axess and Stream before rejoining the main cast in Beast.
Yai is a spoiled and entitled wealthy young girl with very little patience and understanding, and is often annoyed by the calm and levelheaded reasoning of her Navi, Glyde. She is highly intelligent, having skipped to the 5th grade from the 3rd grade to join Lan and the others. Later when she moves to Kingland, she visited sporadically through ludicrous means, such as inviting Lan to a hot spring, only for the hot springs to turn into a rocket and blast him and the others into space.
Despite initially being disgusted by Chaud, she develops affection for him when he helps her reach the top of an underwater hotel during the N1 Grand Prix when the two were trapped in the elevator together, and eventually grows to have romantic feelings for him, which she battles Anetta over with, much to Chaud’s annoyance and indifference.
Through all of her personality, Yai cares deeply for her friends and likes to spend time with them and fights alongside them when in need, though she mostly calls them for favors.
Yai has blonde hair tied with two long braided ponytails and brown eyes. She wears a red dress with pink highlights and a gold button on top, she also wears pink socks with red highlights and red shoes.

- A running gag in the anime is that her forehead is large and so bright that she can use it to blind people temporarily. She actually uses it to her advantage and has even called her "charm point".
- Chaud has a tendency to make fun of her for it, and once got blinded himself, looking at her private jet in the sky while at a meeting.
- In the episode "Secret of the Ayanokoji House!" revealed that the Ayanokoji Family and the Ijuuin Family have been in competition since ancient times. Yai summarized it as a "love-hate relationship".
