Yuki completes her explanation of the Integrated Data Entity and how it relates to herself and to Haruhi. Furthermore, she discusses Haruhi's powers, and how she could destroy and recreate the world on a whim. Kyon, while simply trying to understand all of what Yuki had told him, is initially skeptical of her story. The SOS Brigade gets a new member — a mysterious transfer student by the name of Itsuki Koizumi. On a day off from school, the SOS Brigade searches the city in groups to try to investigate mysteries, during which Mikuru reveals to Kyon the existence of time-travelers. Kyon later confronts Itsuki and learns of the Agency.
