"I'm not interested in ordinary humans. If there are aliens, people from the future, people from another world, or people with super powers among you, just come to me! That's all." This is Haruhi Suzumiya, who made a shocking statement during her self-introduction at the beginning of the school year. Unable to tolerate the dull and boring daily life, she founded an incredible club - Haruhi Suzumiya's group to make the world more lively, commonly known as the SOS Group. Although her classmate Kyon, the taciturn bookish girl Nagato Yuki, the cute senior Asahina Mikuru, and the mysterious transfer student Koizumi Kazuki were all involved, the three people other than Kyon had a big secret that Haruhi Suzumiya didn't know.
