Suzumiya Haruhi no Tsuisou

Suzumiya Haruhi no Tsuisou is a “wandering adventure” game for the PlayStation 3 and PlayStation Portable, published by Namco Bandai Games. It was released as a tie-in to The Disappearance of Haruhi Suzumiya film, taking place shortly afterward in the parallel universe.

After Kyon activated the emergency escape protocol, the Disappearance version of Nagato waited for Kyon's answer. A large error in the time plane prompted Asahina to summon Kyon to repair it. Kyon ended up in The Disappearance alternate world. None of the SOS Brigade, not even Nagato, knew who he was. He made friends with Haruhi by getting her to perform in a band, helped Koizumi and Asahina win "beauty" contests, and helped Nagato's book sale. Afterward, Kyon was able to return to the normal world, but decided to go back for a bit. He helped the alternate SOS Brigade make a movie. Then Kyon returned Nagato's Literature Club form with his name on it. The SOS Brigade (without him) would exist in the alternate world, preventing Nagato from being lonely. Back in his original world at the nabe party, Kyon asked Nagato to go to the library during the weekend. She said she would think about it. However, the visit became a Brigade event instead. There Kyon told Nagato about her alternate self, referring to the alternate as another girl. Nagato said she was sure the other person was happy, because "she lives right there, in your memory".
