Kyon is a cynical and incredulous student of North High School in Nishinomiya. He is dragged along by his classmate, the eponymous protagonist Haruhi Suzumiya, an eccentric girl who is seeking supernatural phenomena and figures such as aliens, time travelers, and espers. With Kyon's reluctant help, Haruhi establishes a club called the "SOS Brigade" (SOS団 Esu-Ō-Esu Dan), short for "Spreading excitement all Over the world with Haruhi Suzumiya Brigade" (世界を大いに盛り上げるための涼宮ハルヒの団 Sekai o Ōini Moriageru Tame no Suzumiya Haruhi no Dan) (In the school's official paperwork Kyon renamed it "Support the Student Body by Overworking to Make the World a Better Place Student Service Brigade") to investigate mysterious events. Haruhi later recruits three additional members: the laconic bibliophile Yuki Nagato, the shy and timid Mikuru Asahina, and the extremely friendly transfer student Itsuki Koizumi. These members soon reveal themselves (to Kyon) to be the types of extraordinary characters that Haruhi is seeking. They have been sent by their organizations to observe Haruhi — who is unaware that she possesses destructive reality warping powers — and to prevent these powers from being unleashed. Each of the three believe that it would be dangerous if Haruhi knew she had such powers. To all of these four the big mystery is why Kyon is in the brigade. Each of the three remarks that Haruhi chose Kyon. All of the four work to keep life interesting for Haruhi and keep her from getting bored and imagining up some new world, as doing this would destroy their world.
