Yuki, who states she is something of an alien, explains the Integrated Data Sentient Entity and reveals that Haruhi has powers that she herself is unaware of but could potentially destroy the world. After a transfer student named Itsuki Koizumi joins the SOS Brigade, the group splits up to search the city for mysteries, during which Mikuru tells Kyon she is a time-traveler assigned to observe Haruhi. Kyon then confronts Itsuki, who admits to being an esper, and tells the purpose of the Agency he is assigned to, confirming Yuki and Mikuru's statements that Haruhi allegedly recreated the universe three years ago.
