Current anime: Special A

Hikari Hanazono has always been second to Kei Takishima. When they were six years old, their pro-wrestling loving fathers introduced them to each other. Assuming that she was the best in wrestling, young Hikari challenged Kei to a wrestling match only to be thoroughly defeated by him. Ever since that fateful incident, Hikari swore to beat Kei in school grades, sporting events - anything. To do this, she has enrolled in the same school as Kei since elementary.

Now she attends Hakusenkan, an ultra elite school, that costs her carpenter father a lot of money. Hakusenkan (or Private Hakusen Academy) is the best school in the prefecture. The classes are separated into A-F based on grades. The A class is only open for the top students in each grade. The top seven within the A class, from first year to third year, are known as the Special A or SA class (hence the title).

The members of SA are highly respected. The SA class has its own building, dubbed "The School's Paradise" and attending class is optional. They also have a kitchen, where Akira makes her afternoon tea. Their uniform is also different from the standard uniform. The members of the SA have been close friends since elementary school.

Hikari and Kei are the top two students in the school, with Kei holding firmly to that number one position. While Hikari considers Kei to be a rival and an important friend, she is completely unaware that Kei loves her.

The story primarily focuses on Hikari and her constant attempts to defeat her one and only rival, Kei. (information from wikipedia)
