Synopsis
Clannad tells the story of Tomoya Okazaki, a seemingly aimless high school student, who starts questioning his bleak outlook on life after a chance encounter with Nagisa Furukawa.
Nagisa, a sweet and determined girl, aspires to revive the school's defunct drama club, and Tomoya, initially out of boredom and later a growing sense of purpose, decides to help her.
As they work towards this goal, Tomoya finds himself drawn into the lives of other girls at school, each with their own personal struggles and challenges.
Through his involvement in their lives, and in helping them overcome their individual hurdles, Tomoya begins to discover a new perspective on life, realizing its complexities and unexpected beauty.
The series explores themes of friendship, overcoming adversity, and finding meaning in the everyday, all while focusing on the growing bonds between Tomoya and the people around him.
