Tomoya Okazaki 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.
He is a childhood friend of Kotomi Ichinose and is best friends with Youhei Sunohara. As he progresses through high school, he meets many new friends, such as Kyou, Ryou, Tomoyo, Fuko, and of course Nagisa. He has a knack for solving the problems of his friends, and seems to care for all of them deeply. He is also seemingly unaware that some of the girls at school show interest in him.
The major story in Clannad is about Tomoya learning about the point of having family and friends. He also has alternate timeline counterparts that end up with Tomoyo and Kyou respectively in the anime.
Ever since his mother, Atsuko, died in a car accident when he was young, Tomoya has been living with his father, Naoyuki Okazaki, 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.
