Answer the questions in The Disappearance of Haruhi Suzumiya in an understandable way.

Let me tell you this, you should read the novel because the animation alone cannot explain the cause and effect

1. Kyon and Asahina traveled through time and space when Kyon returned to the normal world. The world where Kyon went to stop Nagato in order to stop Nagato because Kyon failed the first time, so he had to travel from a further future

2 That mysterious man is Kyon who returned to the normal world. He said that I was in pain too. Then at the end of the disappearance, Kyon said that he would travel through time again to do something, which meant completing the tasks that had not been completed before. Let’s put it this way: a person traveled from two different times and changed in Nagato. There are three Kyons in the world after the world

3 cannot give a definite answer. It is speculated that Nagato has not lost his memory. Chozo who was resurrected due to Nagato's abnormality is the blue-haired MM who wants to kill Kyon, but she is also She is an ordinary person. If she still has abilities, Kyon is not as simple as being stabbed with a knife. Nagato has a good impression of Kyon. It can be said that he likes Kyon. This is the reason. All of this was directed by Nagato, including her amnesia, but Kyon pretended. Kyon's injury is not in the script

4 What happens in the new world will not be reflected in the normal world. Another explanation is that Nagato's ability in the normal world is detailed in Nagato's fundamental obliteration of Asakou Yuko ( Blue-haired beauty) The furniture, luggage, etc. of the Tibetan people are gone and no traces are left. This can be regarded as the law of cause and effect, which erases all effects related to the cause. Since it can be changed by erasing the cause and effect, Cause and effect or tampering with memory can also be used

5 Blue-haired girl Asakou Yuko's Melancholy is a subordinate of Nagato who appeared in a few episodes. He was killed by Nagato just a few episodes ago because he wanted to kill Kyon in order to stimulate Haruhi Suzumiya and obtain information.

The feeling of 6 people is not a joke. In the normal world, there are also various signs that Koizumi has a crush on Suzumiya. Please look for clues yourself

7 This question is actually the same as the third question. Nagato can He said that he likes Kyon. In Melancholy, when Haruhi was about to create a world, Nagato sent a message to Kyon saying, "I also hope you can come back, so all the choices are left to Kyon. This is not just a matter of which world Kyon chooses." It’s also a matter of who Kyon chooses (Nagato Yuki Suzumiya Haruhi)

8 It’s not that the original world is not good, Nagato is emotionless, it can be said that she is a robot. Once she develops feelings, for example, she will never tire of Suzumiya. She is tired of making troubles or has a good impression of Xu, and she does not have such a strong control ability. The emotional blankness makes her make choices based on emotional instincts, and this choice is to change the world
