Tsuyokiss is about the lives of a group of fictional high school students and the often comedic events that occur in their lives. The main protagonist is an average boy named Leo Tsushima who is secretly in love with the eldest daughter of the Kiriya Corporation and who is the student council president - Erika Kiriya.
Later, a senior female student, Otome Kurogane, knocks out several of the main characters one day when they are trying to sneak into school after being late. Surprisingly, it turns out that she is Leo's beloved cousin that he had not seen for years. Suddenly, Otome decides to move into the same house as Leo, whose mediocre life is changing into something a bit more exciting. In the PlayStation 2 version, Leo begins to form relations with Sunao Konoe who is an old acquaintance.
Tsuyokiss Nigakki is the sequel to Tsuyokiss where Leo was not in love to anyone in the first term. At the beginning of the second term, Leo has been worried about what to do after graduation because he does not know what his dream is. Then, Serebu Tachibana transfers to his class and she sits down next to him.
Tsuyokiss Sangakki is the sequel to Tsuyokiss Nigakki where Leo was not in love with anyone during the first or second term.
The anime version's plot of Tsuyokiss differs from that of the video game's in that Sunao Konoe is the main protagonist of the story. Sunao, who finds out the school she transfers to does not have a drama club, becomes determined to form a drama club. Her main obstacle is having to prove to the student council president, Erika Kiriya, that forming a drama club would be worth her time which causes Erika to constantly offer challenges to Sunao for which she must pass in order for the club to be formed.
