Yai Ayano is one of the supporting characters of the MegaMan Battle Network series, along with Glyde.EXE. She is a student at ACDC Town's elementary school and also Lan Hikari's classmate and friend. Yai's NetNavi is Glyde.EXE, who's more of a butler than a fighter.
Although Yai is a young 8 years old lady, she has a very high IQ and skipped school to the fifth grade. Her family is also rich and they live in a mansion in ACDC Town. Her father is the owner of the video game company AyanoTech. Additionally, Yai befriends Mary Towa in Mega Man Battle Chip Challenge.
Yai Ayano is a good friend of Lan, and two years younger than the rest of the crew. Her family is one of the richest in the world. She isn't a very skilled battler in her own right, but her wealth allows her to use rare and powerful Battle Chips to compensate.
Yai is a young girl with fair skin, long blonde hair in two ponytail braids, and brown eyes. Her outfit consist of an red short-sleeve dress with pink collar and trim on sleeve, white socks with pink trim, and red shoes.
- A running joke in the anime, is that her forehead is so (big and) shiny, that she can use it to blind people temporarily. She actually uses it to her advantage and has even called her unique feature, her "charm point".
- Chaud has a tendency to make fun of her a little for it, and once got blinded himself, looking at her private jet in the sky while at a meeting.
- A certain story arc involving her in MegaMan Battle Network 2 created a degree of controversy with parents when she said that if they don't rescue her, they'll "miss the chance to see Miss Yai naked".
- Episode "Secret of the Ayanokōji 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".
- Yai has been revealed to be based after a little island girl named Yaito] from Mega Man Legends 2. Interestingly, her Navi Glyde also is named after a character from that same game.
- She bears some resemblance towards the Mega Man Legends character Tron Bonne, due to their fringes being similar and their hair arcing upwards in similar ways.
