Clannad follows the life of Tomoya Okazaki, a high school delinquent who meets many people in his last year at school, including five girls, and helps resolve their individual problems.

The gameplay of Clannad follows a branching plot line which offers pre-determined scenarios with courses of interaction, and focuses on the appeal of the five female main characters by the player character. The game was ranked as the best-selling PC game sold in Japan for the time of its release, and charted in the national top 50 several more times afterwards.

Story
After the death of his mother, Tomoya Okazaki—a guarded delinquent student at Hikarizaka High School—struggles to not only make sense of the abusive relationship he has with his alcoholic father, but also find meaning in his life. While on his way to class one morning, he meets a mystifying girl named Nagisa. She is a delinquent like him, but only because she is repeating her senior year, unlike the perpetually tardy Okazaki. From their brief encounter, Nagisa decides they should be friends, and enlists Tomoya’s help to revive the school drama club. Not being busy in any way, he decides to join in. Along the way, the two make friends with many other students and try to find both solace and belonging in their endeavors.
