Tomoya is the male protagonist of Clannad. Due to his habit of always arriving late to school, skipping classes during the day, and staying out all night, he has been labeled as a delinquent, or a young person who defies authority. Ever since his mother, Atsuko, died in a car accident when he was young, Tomoya has been living with his father, Naoyuki, with whom he argues constantly. Tomoya was injured during a fight with his father three years ago; since then, their relationship has been very distant.
In the sequel ~After Story~, Tomoya is married with Nagisa in order to get some strength from Nagisa's support. They live happily until Nagisa gets pregnant. Although Sanae had said that it was impossible for Nagisa to have her birth in their apartment due her bad health, she insisted to do it. Nagisa dies in exchange of Ushio's birth. This tragedy brings so much sorrow and regrets to Tomoya. He doesn't want to take care of Ushio for 5 years and become a drunkard. After 5 years full of depression and regrets, Sanae arranges for him to go out with Ushio where he met with his grandmother (it is his father's mother) and makes him realize he is in the same position as his father. Tomoya accepts Naoyuki as his father. Tomoya tries to get out from his depression and sorrows by loving Ushio, the last very precious fragment from his wife, Nagisa. Day by day Tomoya becomes stronger to lift his sorrows although sometimes he cried when he remember Nagisa's smile and his memories with her. One day Ushio's gets ill with the same illness of her mother. Tomoya decide to resign from his job and be with Ushio forever. The snow comes and Ushio is still ill, but Ushio insists to go on a trip with her dad. Tomoya has lost his mind and accept his daughter's demand. On the way, Ushio's health becomes worse and worse until she can't hold it anymore. When Tomoya hugs her, she said that the last trip was fun. Her last word is "I love you dad" and she dies. After hearing those words, Tomoya becomes unstable and calls out to Ushio many times. He also wished that Nagisa could be at his side too. Tomoya has nothing in this world anymore and decides to die while holding his last "fragment" by sleeping in the blizzard.
