Meet Kyon, a typical high school student who has given up on his childhood fantasies about encountering supernatural beings. On his first day at school, he discovers that his classmate, Haruhi Suzumiya, is obsessed with meeting aliens, time travelers, and psychics. Inspired by their conversation, Haruhi creates the SOS Brigade, a club aimed at bringing together these supernatural entities. The initial members include Yuki Nagato, Mikuru Asahina, and Itsuki Koizumi. By the end of the first volume, Kyon learns that these seemingly helpless students are actually part of secret organizations monitoring Haruhi as she is the key to a major catastrophe on the horizon.
