Tomoyo After: It's a Wonderful Life is a sequel to Clannad . The events of the game take place one month after those described in the predecessor. Tomoya Okazaki, the protagonist of the previous game, has graduated from high school and lives alone, working as a garbage collector. One day he discovers that he has a half-sister, his father's illegitimate daughter. Tomoyo Sakagami, Tomoya's friend and one of the main characters in Clannad , offers to take care of the girl. The story then focuses on the personal problems and relationships of these characters.
The game is primarily a visual novel, with the player making occasional decisions that move the story forward. Locations and events are displayed as still images accompanied by text. In order to access all the scenarios, however, the player must participate in a simple turn-based RPG called "Dungeons & Takafumis".
The PC version of Tomoyo After contains scenes with nudity and explicit sexual situations.
Tomoyo After: It's a Wonderful Life was released for the PSP in 2006, and later for PS3, Nintendo Switch, and PC. The PSP version includes updates such as additional scenarios and CG events, while the PC version has full voice-acting for the main character.
