Takumi Kaizu is a somewhat non-typical boy: he doesn’t have much interest in the opposite sex. His best friend, Osamu, refuses to believe such a thing and makes it a point to find out who it is that Takumi really has a crush on! His choices are plentiful: solemn and creepy Chiwa, violent Shinano, his step-sister Sana, the school’s idol Wakana, childhood friend Konami, and more! With so many girls around him, who will Takumi end up falling in love with?
Tomoya Okazaki is a third-year high school student who is generally bored with life and doesn't take his studies, future, or anything else seriously. One day, however, he meets a lonely-looking girl in the school courtyard, Nagisa Furukawa. She explains to him the source of her loneliness: she had missed a lot of the previous school year and thus is repeating her third year; everybody that she knew has already graduated, and she is lonely. Tomoya is rather indifferent at first, but decides that he has nothing better to do and spends increasingly more time helping Nagisa restore the school drama club. As his relationship with Nagisa grows, Tomoya begins to open up to various other people around the school as well...
_summer and Clannad seemed like an obvious combination, solely for the opening episodes and general feel. Both explore the relationship between different characters and while some have very similiar personalities, the sense of humour and storyline prove that it is easy to watch one and then the other.
