After closing a time loop fiasco in The Disappearance of Haruhi Suzumiya (Vol. 5), our hero Kyon is ready to start a new year with a blank slate--no time travel, no apocalyptic worries, and maybe some actual peace and quiet with the SOS Brigade, a club comprised of his high school''s most extraordinary students. Their leader is Haruhi, a bold, brash girl who doesn''t realize that she''s actually a powerful goddess whose moods can easily change the balance of the universe.

Just as Kyon starts to get comfortable, he gets a visit from his friend Mikuru. Except this isn''t his Mikuru; it''s a Mikuru from eight days in the future! Time traveling shenanigans start all over again as Kyon, guided by the future Mikuru, attempts to stop a terrible future from becoming a reality.
