Special A

Kei invites Hikari to his house because his father wants to talk about pro-wrestling with someone. She unexpectedly becomes tutor to Kei's younger brother, Sui, who has a rather strained relationship with Kei, and tries to bring the brothers closer together.

The Student Council and S.A challenge each other to see who will organize the upcoming school festival, but Hikari and Kei end up arguing; Hikari joins the Student Council's side and Akira soon follows. While Kei takes them all on single-handedly, Hikari learns that he has always done everything alone.

Because of some intervention from Sui, Hikari ends up being Kei's date at a birthday party for Yahiro Saiga. While wondering how Yahiro fits into Kei's past, Hikari is shocked to hear from Yahiro that Kei is in love with her.

Unable to believe that Kei is in love with her, Hikari behaves strangely around Kei after Yahiro's party and refuses to tell him why. To determine where the S.A will go for their vacation, Kei suggests a contest where the winner decides - with the condition that if he wins, Hikari will tell him what Yahiro said to her at the party.

The S.A head off to Hawaii for their summer vacation, but end up playing "family" to Chitose, the spoiled and demanding son of a client for Ryuu's family. He is particularly harsh with Hikari, but she is determined to make sure he has a good time, even if it means being the dog in Chitose's family.

Hikari joins Yahiro and Chitose at their villa in order to find out why Yahiro's relationship with Kei and Akira is so strained, but ends up becoming his prisoner so that Yahiro can force Akira to see him again.

The greenhouse is vandalized and it seems that Hikari has a hunch on who may have commited the act. When she comes face to face with the suspect, he challenges the S.A - however, it must be Ryuu who completes the challenge. Old memories and feelings resurface for Ryuu while Hikari learns more about her friends.

Having lost, yet again to Kei, Hikari will have to spend the day with him. However, Kei's father takes him to Shanghai. In his absence, Tadashi asks Hikari to be his girlfriend, or at least pretend to be in front of his mother, the Director of the Hakusenkan.

Tadashi's lie to his mother results in the Special A being forced to spend three days in separate classes at a regular high school. In her class, a girl named Yui Oikawa tries to befriend Akira. However, Yui's resemblance to a former friend causes Akira to act rudely to her.

Akira's determination to protect her new friend, Yui, from Yahiro ends up pushing Yui away instead. Meanwhile, Yahiro's attempt to separate Akira from Yui comes with well-meaning intentions that Akira may never realize.

Hikari must go on a date with Kei on Sunday, as promised when he was recovering from a fever. However, their "date" is interrupted by Sakura Ushikubo, Kei's future fiancée, who takes Hikari away and befriends her. When she agrees to help Sakura find out more about Kei, Hikari begins to feel some unexplainable feelings regarding Kei.

Kei has recovered from his fever and Hikari must go on a date with him. Things don't seem to be doing so well, when Hikari learns that Kei's father has arranged a marriage between him and Sakura Ushikubo.

The S.A. is invited to attend and plan a festival at Kokusen Academy by Sakura and Yahiro. Yahiro tries to tell Akira he cares about her, but decides against it when he realizes that she has feelings for Tadashi.

Upset that Tadashi does not seem to care about her, Akira goes to a matchmaking party with Sakura. When Tadashi apologizes to her, she becomes angry at herself for causing trouble. Yahiro helps Tadashi find a way to comfort her, and Tadashi decides to bring Akira to a viewpoint that they had been to when they were children.

Megumi asks Yahiro out, claiming she has a crush on him. Yahiro thinks there's more to it and agrees only if she's willing to play a "game" where she must make him say he liked the date before he believes she likes him. Meanwhile, Hikari catches a cold and the rest of the SA go to see her. When Hikari's parents leave her friends to take care of her, they find the feverish Hikari doing rather outrageous things.

Hikari, Kei, and Jun attend the opening of a new athletic park and run into Sakura. Jun avoids Sakura, who chases after him in hopes of discovering his true feelings for her, while Hikari and Kei must deal with the scores of girls that Jun's alter ego keeps attracting.

Hikari meets Aoi Ogata, a member of the Takishima Group who finds Kei important to him and is willing to do anything for Kei. When Aoi decides Kei is better off studying in London, Hikari must prove she's worthy of being Kei's rival. However, this meeting with Aoi causes Hikari to think about her true feelings for Kei.

Hikari struggles to figure out her feelings for Kei and finds it increasingly awkward to be around him. After spending the day together, she realizes she loves him - but stops short of a confession. Meanwhile, Aoi has approached the Director of Hakusenkan and leaves her with no choice but to lock up the S.A's greenhouse for reasons unknown.

Thanks to Aoi, the S.A class has been disbanded in order to force Kei to go to London. So that Hikari and his friends can remain together, Kei proposes a challenge to Hikari that if she wins, he will bring back the S.A. However, Hikari learns too late what Kei has done in order to bring back the S.A - he has already left for London for her sake.

Hikari and S.A head to London to find Kei and bring him back to Japan while Kei resigns himself to not seeing Hikari and his friends again. Everyone, including Yahiro and Sakura, overcome the obstacles standing in the way of reaching their friend. When Hikari meets with Kei at last, they finish the challenge he issued her and express their true feelings for one another.
