Higashi no Eden - Season 1

Saki Morimi has just graduated from college and is visiting Washington D.C.. When she gets into trouble with the police, a mysterious Japanese boy helps her out. The boy appears to have no memory and is completely naked, carrying only a gun and a cell phone. Juiz, who claims to be his concierge tells him over the phone that his memory was wiped. Later he takes on the identity Akira Takizawa and decides to go back to Japan along with Saki. While waiting for their flight, they watch a news covering a missile attack on Tokyo.

After they arrive in Tokyo, Akira confesses to Saki that he has no memory before they met in Washington. Saki goes along with Akira to help him track the address mentioned as his residence on his passport. On the phone Juiz tells Akira that it is his responsibility to spend 8.2 billion yen that the phone is charged with. Meanwhile Kondō is tracking Akira by the places Akira is using the phone for payments. Akira walks up to Kondō and starts a conversation with him after he notices that both of them have the same cell phone. Kondō questions him about Selecao, but Akira does not remember anything.

Akira and Saki arrived at the building which address was written in Akira's passport. It turns out to be a Shopping mall. After they looked around , Saki is watching a movie in the mall cinema. Meanwhile Kondo followed Akira and Saki and enters the building too,with the intention to take away Akira's cellphone. After he finds him in the movie instructor's room, he beats him up and takes Akira's cellphone. Unfortunately Juiz tells him that the cellphone works only with fingerprint authorization and his efforts are in vain. He then gets a call from Akira and after he was told that he's got his notepad they decide to meet up in the Kabuki district. There Kondo is stabbed with a knife by his wife because he betrayed her. When Akira arrives, Kondo tells him to track down the other Selecao members and to be wary of the organization. Selecao gave ten other individuals 10 billion yen to spend, with the catch that if any of them had their money count drop to zero, they will be killed. Before dying, Kondo believes that Selecao arranged his death by leaking evidence of his affair to his wife.

Following Kondo's advice, Akira goes to track down the other Selecao members. He eventually manages to find Selecao number V, Hajime Hiura who is an influential brain surgeon. Hiura at first suspects Akira to be the Supporter, the Selecao tasked to observe the other Selecao members and to punish them if they break any of the rules. After being assured Akira is not the Supporter, Hiura tells him about Selecao. It is an organization run by Mr. Outside, an enigmatic individual who chose twelve individuals, and gave them ten billion yen each with the condition to use the money to save Japan. If the Selecao members refuse, run out of money, or act in a manner unbecoming of a "messiah", then they are to be eliminated by the Supporter. Shortly after Akira leaves, Hiura is murdered by the Supporter since he had run out of money.

As Akira contemplates the power he has as a Selecao, he is confronted by a stranger who had known him before he had erased his memories. It is implied that the stranger was one of the missing NEETs, since he is angry at Akira for ditching him and his fellows in Dubai. However, grudgingly thanks him since his experiences there helped him reintegrate into society. Realizing that he had forgotten about Saki, Akira asks Juiz to locate her. As he does this, Selecao's No. 1 and 11 take notice of Akira's activities. Meanwhile, after returning home, Saki prepares for her prospective job interview, but she is rudely turned down. She finds Akira waiting for her outside the building and goes with him, venting about how the adults do not care for the younger generation. Akira then kisses Saki and assures her that he will help her. Meanwhile, a heartbroken Ohsugi, who saw Saki leaving with Akira, goes to a restaurant and drowns his sorrow in alcohol. As the drunken Ohsugi leaves the restaurant, Selecao's No. 11 comes across him.

Saki returns to her friends in Eden of the East, a recycling club at their University, and tells them about Akira. They soon become interested in (and suspicious of) him and decide to go visit him. Akira warmly greets them and informs them that he had found out about their club's special commodity. They have developed a revolutionary image recognition program, but have stalled due to problems at the University. Akira offers to help Eden of the East in their goal, in exchange for having them help him on his duty as a Selecao. Encouraged by Akira, Saki decides to stay in the club. Meanwhile, Hirasawa receives a call from Kasuga, who had been tasked with finding Ohsugi. Kasuga suspects that Ohsugi may have been kidnapped by the "Johnny Hunter", a kidnapper reputed to have almost 20,000 victims, according to a story circulating over the internet.

The Eden of the East members begin to receive pictures from Ohsugi. Takizawa uses his phone to find him. Juiz is able to locate him in the Hotel Insomnia where he was taken after being kidnapped by the "Johnny Hunter". The hunter is Kuroha Diana Shiratori, Selecao #11. Juiz helps the two counter each other's attempts to stop one another from reaching the hotel, but they both meet in the hotel room. Kuroha explains that she cuts off men's "Johnnies" and murders them as an act of revenge. Takizawa confronts Kuroha and offers to show her the love that she had not received from any man. However, he passes out from wounds he gained trying to reach the hotel. Saki follows Takizawa to the hotel to find Kuroha tending to his wounds. Kuroha reveals that her prisoner is not Ohsugi, but is in fact a wanted rapist, and muses how she could have possibly mistaken one for the other. Then using an elaborate illusion, she escapes.

Takizawa wakes up to find Saki tending to his wounds, and that Kuroha had disappeared. Meanwhile, Ohsugi returns to Eden of the East, telling them that he was invited to a drinking party and had his bag stolen that night, which caused the misunderstanding. He shows his displeasure about them associating with Takizawa and leaves. He then takes a picture of Takizawa and registers to Eden's program, hoping to find out his identity. Takizawa then arrives and asks Eden if they could repair a Selecao phone (which belonged to Kondo). Hirasawa suggests he go visit "Pantsu", a computer prodigy, and sends Saki and Micchon with him to keep and eye on him. While Saki and Micchon go to the convenience store, Takizawa talks to "Pantsu" about Selecao and gets "Pantsu" to let him in. Meanwhile, Ohsugi checks on Takizawa's picture and finds out that the users all identify Takizawa by different names and aliases. Concluding that Takizawa must be some kind of criminal, he calls Hirasawa in a panic to warn Eden.

"Pantsu" manages to recover the complete Selecao transaction history from Kondo's phone, and discovers that the Selecao were indeed responsible for Careless Monday, as well as a series of mysterious evacuations in the targetted areas beforehand that ensured there were no casualties. Takizawa was also apparently responsible for the 20,000 missing NEETs. Takizawa makes "Pantsu" promise not to tell Saki or Micchon about what they had discovered, and leaves the phone with him in hopes of fully repairing it. Before they leave, Saki asks "Pantsu" about the phone, but he warns her that she is better off not knowing. Meanwhile, Mononobe, Selecao #01, and Yuuki, Selecao #10, follow Takizawa to Kyoto, curious about his intentions. "Pantsu" discovers that Selecao No. 10 was responsible for the missile attacks, and that it was Takizawa who arranged the evacuations, making him a hero. He then discovers something shocking and rushes outside to warn Takizawa only to be run down by Mononobe, who destroys Kondo's phone before calling Takizawa. Back in Tokyo, Eden meets Ohsugi at Takizawa's theater, where they discover the area where the 20,000 NEETs were held and writing on the wall declaring, "I'll kill you, Takizawa Akira!"

Saki and Micchon board the train to go home but Takizawa doesn't. Takizawa is confronted by Mononobe who offers to reveal the truth about the game and himself. Takizawa then receives a call from Saki who reveals that she overheard him when he confronted Kuroha. Takizawa tells Saki to stay on the line and listen to his and Mononobe's conversation. Meanwhile, Eden investigates the theater and receive a large amount of data from Itazu. Takizawa and Mononobe talk about the missing NEETs and Mononobe tells him who he believes Mr. Outside is, a man named Ato Saizo who is the president of the ATO company. Ato Saizo was a great political figure who helped fix Japan but probably died of terminal cancer, though the game still goes on because of the Supporter. Mononobe tells Takizawa that he will become Mr. Outside and take Juiz. Takizawa and Mononobe arrive at a research facility managed by the ATO Institute. Meanwhile, Eden uncovers the data and it shows the Selecaos' spending logs. Eden then looks outside to see a ship full of naked people who they think are the missing NEETs and flee. Mononobe, along with Yuuki and Selecao #2 Tsuji, plan to launch more missiles and tell Takizawa not to get in their way again as they tell him why he erased his memories. Takizawa was in despair after he had been betrayed by the people he attempted to help, and he leaves. A woman then comes in telling the three Selecao that there will not be a winner tonight. Monobe checks his phone to see that Juiz has been moved to a hidden location, and Mononobe says that Selecao #12 is the Supporter or maybe even Mr. Outside. The final scene shows Takizawa sitting on a train and Saki crying on the floor, after realizing that she had betrayed Takizawa by hoping something bigger than Careless Monday would happen.

Saki and Micchon return to the multiplex, which has been invaded by the 20,000 NEETs. Saki explains to Eden that Takizawa recruited the NEETs to help evacuate citizens before Careless Monday, disguised as government personnel. However, in order to cover his involvement, Takizawa took responsibility for Careless Monday and shipped the NEETs to Dubai for three months to keep them out of the public eye. Out of guilt and despair for what had happened, Takizawa erased his memories. After analyzing the data, Eden discovers that the missiles are targetted all over Japan, including the multiplex. Takizawa then contacts all of the NEETs and tells them he has arranged a bigger missile attack, and instructs them to figure out the best way to intercept the missiles and upload it to Eden. Using the NEETs' collective knowledge, Juiz organizes a network of jet fighters and Patriot missile launchers to intercept the missiles. Everybody, including Itazu and the remaining Selecao look on as the missiles are destroyed. Knowing that this event will be much harder to cover up than Careless Monday, Takizawa instructs Juiz to use all of his remaining money to make him "King of Japan". His reasoning is that there are many smart people in Japan, but none of them are willing to bear the responsiblity of leadership, so it is up to him to take it. In order to become King, Takizawa uses his phone to brainwash himself and he slips it into Saki's pocket. The episode ends with Saki contemplating what will happen to Japan now that Takizawa is a prince.
