Prologue Arc

Lore & Background

Haruhi soon recruits three additional members: the laconic bibliophile Yuki Nagato, the shy and timid Mikuru Asahina, and the unflappable transfer student Itsuki Koizumi. Over time, these members reveal themselves to Kyon to be the extraordinary characters Haruhi seeks: Yuki is an alien interface sent by a hive mind; Mikuru is a time traveler sent from the future; and Itsuki is an esper that works for a secret society. Each has been sent by their respective organizations to observe Haruhi, who is unaware that she masters the powers of a god. Haruhi's powers grant her the ability to create and destroy the fabric of reality on a whim, activating without her knowledge whenever she wills really hard for something to happen or when she is in a bad mood. Each organization believes that should Haruhi learn of her powers or be put in a bad enough mood, it could destroy the entire universe. The three club members, together with Kyon, work to keep life happy for Haruhi to prevent such an apocalyptic scenario under the guise of being part of the SOS Brigade, as well as combating external threats that seek to exploit Haruhi, all while forming a bond as a band of misfits.

In Their Own Story

Kyon sits in class at North High School, having deemed the notion of an extraordinary life childish, now seeking little more than a normal life. Haruhi Suzumiya sits behind him, an eccentric schoolgirl constantly seeking to make life more interesting. One day, Kyon accidentally plants in Haruhi's head the idea for her to start a club to engage in her eccentricities. She establishes the SOS Brigade, short for "Spreading excitement all Over the world with Haruhi Suzumiya Brigade" (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, roping Kyon into being a member himself.
