Clannad is set in a high-school located in some Japanese town. Okazaki Tomoya is a third-year student who doesn't take his studies seriously. Always late for class, he's seen as a delinquent by the rest of his classmates who are busy preparing for their entrance examinations. Needless to say, he hasn't too many close friends either.<br><br> Tomoya seems not to mind too - until one day he meets a girl, Furukawa Nagisa, who is left alone without friends on this school, because everybody she knew already graduated. What a clumsy girl, he thinks at first. But he can't leave her alone and so, while helping her, he meets a few other girls from his school. Although he doesn't care much about them at first, he soon opens his heart to them as they get to know each other better.<br><br> (Source: AniDB)
