When Hikari was little, she and her father liked to watch professional wrestling, and she became very good at it. She is the pride of her family until she is introduced to Kei, the son of her father's friend.

At six years old, Hikari Hanazono was unbeaten at pro-wrestling until she was easily defeated by Kei Takishima. Since that day, she has vowed to defeat Kei, who proves to be remarkably talented at whatever he attempts, at anything and convinced her father to allow her to attend the same expensive elite schools as her rival.

The S.A is challenged to a pro-wrestling competition by the Student Council President, Hajime Kakei. Hikari and Kei accept the challenge, but run into trouble when the President decides to use underhanded tactics to beat them and Kei begins to worry about Hikari's safety without considering her feelings.

Hikari, having lost a bet to Kei in the previous episode, agrees to make a bento for him. However, despite how hard she tries, all Hikari's attempts to cook something wonderful for him to eat prove to be disastrous.

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.
