Much to his chagrin, Kyon, along with the silent bookworm, Yuki Nagato,
the shy and timid Mikuru Asahina, and the perpetually smiling Itsuki
Koizumi, are recruited as members. The story follows the crazy
adventures that these four endure under their whimsical leader, Haruhi.
The story is based on the light novels by Nagaru Tanigawa.
