For freshmen Yu and Ai Asai, having a twin means having a best friend. When asked a series of questions about the preferences of her twin, Yu had no problem rattling off Ai’s favorite color, food and book.

The two share a special bond, according to Yu.

Yu’s name means “gentle” in Japanese, while Ai’s name means “love,” according to Ai. The sisters, who were born in America, lived in Japan from ages 3 to 9 and came to Saratoga High from Fisher Middle School in Los Gatos.

“We didn’t know any English, so it was hard,” said Yu. “It was tougher then, but it still kind of is.”

Yu said she and her sister share many similarities and sometimes think the same things.

“My sister and I do everything together,” said Yu. “We feel the same things and say the same things.”

Despite frequent arguments, the sisters say these fights bring them closer together.

“Fighting bonds us a lot,” said Yu, “even though we get annoyed with each other. We are kind of like ‘frenemies.’ ”

The sisters knew many of each other’s preferences, but not necessarily everything. Color, music and school subjects were easy questions for both, but when asked more obscure questions about the other, such as their favorite superhero or movie, they were stumped.

The quiz revealed differences in the tastes between the twins; Yu likes science and math, while Ai likes English. When asked what they would bring if stranded on an island, the results were amusing.

“If I was stranded on an island, I would bring my twin because she’s quite useful,” said Yu.

Ai, on the other hand, replied: “If I was stranded on an island, I would bring my French poodle, Minnie Mouse, because she would keep me company, and we could find food together and share.”
