Tsuyokiss: Cool×Sweet

Sunao Konoe and her family have recently moved to a new town which makes her a transfer student to her new high school. Upon arrival, Sunao meets a multitude of other students and already starts making friends and rivals. Upon discovering the school has no drama club, she becomes very determined to create one, though the student council president still stands in her way.

Sunao does not want to give up on creating a club for those who are fans of the theater and tries diligently to get people to join her cause. Unfortunately, the student council have had something planned for months which will squander Sunao's chances once again.

The Athletics and Martial Arts Festival is about to start and Erika offers up a challenge to Sunao which is if Sunao's team can defeat hers then she will allow Sunao to form the drama club.

Sunao practices a play and in the process helps Nagome deal with the loss of her deceased father.

Sunao begins a part-time job to buy some equipment. Turns out her new job, and co-worker, is a lot more than she bargained for.

At the student council's annual survival camp Sunao and Leo fall into the ocean and find themselves surrounded by sharks. Also, Leo and Otome understands the true meaning of 'daikon' and Sunao's feelings towards it.

The classes compete in a facility test with the loser to wear daikon costumes. Leo apologizes to Sunao for a past misunderstanding and her aversion to daikon disappears.

At the festival Sunao becomes isolated from everyone and spends the afternoon with Leo, alone together.

Sunao uses the school cultural festival as a basis for forming the acting club.

Sunao finally gets to act in front of her peers, though after seeing Leo and Otome together and overhearing Otome's conversation about their closeness, Sunao becomes distracted.

Sunao is hesitant to confront Leo about her feelings for him. Several of her friends encourage her and she learns Otome's true feelings when confronted by her.

Sunao confesses her feelings to Leo, whom she longed for him from ten years ago. Meanwhile, Sunao faces-off with Erika in the school presidential debate by using her acting talent in front of the entire school.
