This episode begins where episode 3 left off – Nagato telling Kyon that she is an alien. She now informs him that she is here to observe Haruhi and report all obtained data to the Integration Thought Entity. Apparently Nagato was born (or created) three years ago for this particular task. For those three years, nothing much had happened until Haruhi met Kyon. She explains about a whole lot of other things that I can’t be bothered writing down. All you need to know is that Haruhi was the centre of a massive explosion of data and that she is no ordinary human. She is able to manipulate data around her to coincide with her own desires. Nagato then goes to say that Kyon has been ‘chosen’ by Haruhi, without explaining what this really means.

 

Of course, Kyon does not believe a word Nagato says, and thinks she is crazy.

 

Nagato continues her speech, saying that she is not the only interface placed on earth (in fact, another person in Kyon’s class is one).

 

The next day, the mysterious transfer student arrives just as Haruhi had wished for it. After school as Kyon, Mikuru and Nagato are waiting for Haruhi, Nagagto begins to play a board game with Mikuru. Mikuru is very uneasy about this (as she knows Nagato is an alien). However, before anything else can happen, Haruhi arrives to destroy the tranquillity, dragging along the transfer student, Koizumi Itsuki.

 

After school the next day, Kyon walks in on Haruhi stripping Mikuru. Kyon runs back out. It turns out that Haruhi had gotten Mikuru a maid costume. After Koizumi joins them, Haruhi gives a not-so inspirational speech, and so the SOS Brigade go out in search of mysterious happenings around the neighbourhood.

 

The club splits into two groups. Kyon is paired up with Mikuru, and the other three are grouped as a three. After this decision is made, Haruhi constantly reminds Kyon that he is not on a date, even though he thinks it is.

 

As Kyon and Mikuru walk around, she decides to inform him about her true identity and that she is from the future. The conversation is extremely long as Mikuru tries to explain about time which is incomprehensible to normal humans. She then tells him that three years ago, a large timequake was detected and people from her time came to investigate. They were shocked to find that they weren’t able to travel further back in time. The conclusion was a large time-fault was created during the timequake. And the reason for this timequake? Haruhi of course. Like Nagato, Mikuru also claims that Kyon was chosen by Haruhi. The details are classified so she cannot explain further.

 

The SOS Brigade regroup, have lunch then split up again. Kyon is paired with Nagato. Haruhi is not happy as she obviously wants to be with Kyon, but the groups stay as they are. Instead of searching for mysterious things, Kyon takes Nagato to the library to kill time. Kyon falls asleep and is woken by his mobile. After yielding no results, Haruhi calls it a day and everyone goes home. The next week, Kyon confronts Koizumi, expecting him to be out of the ordinary as well. And it turns out he is. Koizumi is an esper and like the other two times he begins to explain about himself and the agency he is from, which was created three years ago. He describes the world as a dream, and for the person having this dream, manipulating it is easy. And who exactly is having this dream? Suzumiya Haruhi. Koizumi describes her as a god.
