Clannad is a story of a high school boy Okazaki Tomoya,
and the relationships he has with the various students in school.
There are five main girls, and there are stories with each one.
The name "Clannad" implies something to do with "family",
and most of the characters have some unusual family settings.
Clannad was originally a game for the PC (2004),
but games for other platforms followed.
Some drama CDs were released in 2007, a movie was released in September 2007,
and two TV anime series were aired (October 2007 to March 2008 and
October 2008 to March 2009).
