Tomoyo After ~It's a Wonderful Life~

Tomoyo After ~It's a Wonderful Life~ is an erogē visual novel, released by  on November 25, 2005, approximately one year following the release of Clannad. The game focuses on the relationship between the protagonist, Tomoya Okazaki, and the title character, Tomoyo Sakagami, where it serves as a continuation of Tomoyo's route present in the original visual novel, Clannad, starting off several weeks after the events of her route present in that visual novel (Clannad).

Plot
The plot of Tomoyo After occurs following the events of the Clannad visual novel (most specifically the events of Tomoyo's route in that visual novel (Clannad) since it (the plot of Tomoyo After) directly takes place sometime after the events of her route in Clannad), beginning in June 2004, which is several weeks after the ending of Tomoyo's route in Clannad where Tomoya graduated from high school in the spring and Tomoyo becoming student council president and saving the cherry blossom trees. It is set in the fictional city of Hikarizaka. Building on the events of Tomoyo's route in Clannad (makes sense considering that Tomoyo After chronologically takes place after the events of her route in Clannad), Tomoya lives alone, having been estranged from his father, and works as a garbage collector. A romantic relationship develops between him and Tomoyo, with whom he has remained close friends. Tomoyo's character has changed from how she appeared in Clannad. Having given up on her promising future and dreams of attending university, she appears content to become a homemaker.

As the game progresses, it is revealed that Tomoyo has an illegitimate half-sister, Tomo, who moves into Tomoya's apartment due to her mother's psychological instability. Tomoyo greatly loves Tomo and dotes on her throughout the game. Takafumi, Tomoyo's younger brother, also moves into Tomoya's apartment, and installs a personal computer in Tomoya's room. The group is later joined by Takafumi's ex-girlfriend, Kanako. Kanako has left home due to her mother's remarrying and is shown as a cynical and foul-mouthed freeloader.

Tomoyo After focuses on the struggles of the different characters while keeping the focus on the importance of family, just like the main story of Clannad.
