Re: Repeating a Life in Another World From Zero
Published on April fools of 2016, Tappei Nagatsuki wrote a chapter, commonly known as Kasaneru or Greed IF, where Natsuki Subaru accepted the contract which Echidna offered. The actual chapter starts after the fourth arc.

Summary
After Subaru made the contract with Echidna, he decided to use his Return by Death to solve all of his problems, in his goal to save everyone and eventually make Emilia king. With Echidna advising him, Subaru was able to take care of the problems which he faced in Sanctuary and saved everyone.

After returning by death over 100 million times and losing count, Subaru woke up as usual at the Mather's Mansion on the 14th of Kissdam. He got out of bed, and after washing his face, he practised his smile in the mirror. After doing so, he visited Echidna's dream world using the pendant at his neck as per his usual routine.

After a rather blustery conversation with Echidna, Subaru returned back to the real world where he was greeted by Petra Leyte coming to wake him up. Following her wake up call, Petra expressed her concerns to Subaru about whether the weather would get worse later in the afternoon as she planned to go shopping.

After Petra's departure, Subaru's daily routine started. He first visited the mansion's courtyard to find Garfiel Tinsel and Reinhard van Astrea sparring. This was a daily occurrence for them as Garfiel aimed to grow stronger. Garfiel had been greatly affected by the events that had transpired back at the Sanctuary, and had struggled to keep the time of its liberation at bay as Subaru had tried to isolate him from the other villagers. In the end he could not avert Sanctuary's fate and he would have perished to the Great Rabbit, if Subaru and Roswaal L Mathers hadn't saved him. This resulted in Garfiel being extremely belligerent towards Subaru, joining the Emilia camp only at his sister Frederica Baumann's request.

This time as well, Garfiel was defeated by Reinhard, and the former retired back to the mansion. Reinhard had been recruited over to the Emilia camp by Subaru after he used his Return by Death to eventually convince Felt to abandon him, leaving Reinhard emotionally broken. After Reinhard retired back to the mansion as well, Echidna speaking to Subaru as thought-waves through his pendant tried to reassure him he had made the right choice.

Continuing with his daily routine, Subaru went to visit Beatrice who had holed herself up in a room rather reminiscent of her old forbidden library which had burned down in Roswaal's old mansion. Beatrice had sunk into a deep depression as Subaru had torn her out of the library against her will during the events of Sanctuary. During his visit, Subaru tried to comfort her, but he was met by her scratching his face and neck. After leaving the imitation library, Subaru reflected on whether he had made the right choice back then, and wondered if he should have lied to her and said he was "That Person". Once again, Echidna tried to reassure him that he had made the right choice and said that with time she'd open up to him so that her emotional wounds could be healed.

As he continued to the next area of his daily routine, Subaru happened to come across Roswaal who was in high spirits. The two had a brief discussion in which Roswaal affirmed that the two of them would mutually cooperate with each other to achieve their most cherished desires. Subaru, who wasn't all too happy with being used like this, begrudgingly continued on with this day.

Subaru made his way to the room which Rem was in. She was still comatose due to Gluttony's effect. Ram was in the room on Roswaal's orders. She had been ordered to be extremely polite to Subaru, and had no real interest in her comatose sister. Subaru asked her to leave the room, which she did. Left alone with the comatose Rem, Subaru called for Echidna's help. He asked her to remind him what the ways to wake up Rem were. Echidna listed three reasons, but advised him to go for the last one which was to get the blood of the dragon by making Emilia king. Subaru pledged that no matter how many times he would die, he would wake Rem up.

Finally, Subaru arrived at the end of his daily routine, where he visited Emilia's room. Emilia was in a fragile mental state due to the fact that she couldn't surmount the trials back at the Sanctuary. She noticed Subaru's scratch marks and immediately realised they were from Beatrice. She lost control of herself and started to freeze the mansion. Subaru was able to luckily clam her down due to having practised his smile in the mirror earlier. After her outburst, Subaru told her to study for today and that he'd dine with her later. As he talked to Emilia, Echidna butted in and started to slander Emilia, continuing to do so even after Subaru left Emilia's room.

After dining with Emilia, Subaru had a flashback to when Otto Suwen left the Emilia camp one year ago. The flashback caused Subaru great distress, agonising about whether he had taken the optimum choices when he was Returning by Death. As he agonised over it, he found himself back at his room, where Elsa Granhiert was awaiting him. Elsa had joined the Emilia camp after the events of Sanctuary and was currently entrusted with the mission of finding where Gluttony was at.

After some talk with Elsa, in which Subaru learnt that the latest location she had investigated turned out to also not have the Gluttony Archbishops, Subaru asked her what the weather was like beyond the forest. Confused by his question, Elsa replied that it looked fine. Subaru nodded and commanded her to kill him. Elsa was a bit confused by the question, but obliged, and lopped off Subaru's head.

Subaru returned by death not knowing which day he had returned to, realising his save point had changed. In a panic, he rushed to Echidna's dream world to find out what day it was. He eventually learnt from her that it was the 14th of Kissdam. Echidna realised that Subaru had used his ability to reset, and both of them steeled themselves knowing that trouble was brewing in the future that Subaru would have to confront. In addition to this, Echidna asked him why he had used his Return by Death, but Subaru declined to answer.

After leaving the dream world, Subaru was once again greeted by Petra. This time when she voiced her concerns about whether the weather would be fine for when she went shopping, Subaru reassured her and said it was. Petra found that reassuring, but asked him how he knew. Finally, Subaru answered the question by saying that it was because he had returned just for this, risking life and death.

Meanwhile, back at the dream world, Echidna was enjoying her tea reflecting on the events that had happened. She found herself fascinated by Subaru and his persistence, and declared that she'd give it her all to help Subaru protect the ones he cared about. Despite her spiel which was presented as her love of scorching flame, she voiced out a contradiction at the last. "Ah, even so-- Why does love always fade?"

Re: Erring a Life in Another World From Zero
Published on April fools of 2017, Tappei Nagatsuki wrote a chapter, commonly known as Ayamatsu or Pride IF, where Reinhard didn't help Natsuki Subaru during the first arc with rescuing Emilia from Elsa , what after 88 deaths made him fall into the dark side.

Re: Drowning a Life in Another World From Zero
Published on April fools of 2018, Tappei Nagatsuki wrote a chapter, commonly known as Oboreru or Wrath IF, where Natsuki Subaru accepted Beatrice's assistance against Ram during the second arc.

Re: Cobbling Together a Life in Another World From Zero
Published on April fools of 2019, Tappei Nagatsuki wrote a chapter, commonly known as Tsugihagu or Gluttony IF, where Murder became a habit for Natsuki Subaru, and started to read the victim's Book of the dead during the sixth arc.

Summary
Diverging from midway through Arc 6, after Natsuki Subaru decided to enact his plan to find out who his old self, "Natsuki Subaru" was by reading everyone's books of the dead, Subaru found himself in a remote region in Northern Lugnica after slaughtering a multitude of people who knew him on his journey to cobble the pieces of himself back together. In this remote region, Natsuki Subaru kept repeating a question to Amyu Sears (アミュー・シアーズ). He kept repeating "Hey, do you know my name?" to her. After some deliberation, the frightened young girl who was 14 years of age answered she didn't. Subaru, who was implied to have killed everyone else in her village, let her live.

Far prior to this event, Subaru stopped at the side of the main road to have lunch with Emilia, Beatrice, Ram, Julius Juukulius and Meili Portroute whom he had murdered back at the tower, and now appear as vivid hallucinations that speak to him quite friendly. After some lighthearted discussion with them about the perks of mayonnaise, all those individuals freeze in time, and fade from sight. In fact, Subaru only has one companion with him along the road, and that is Shaula.

As the two of them continue their journey down the main road, they meet Regin Suwen. After having realised that Regin knew the old "Natsuki Subaru", Subaru stopped to talk to him. Regin quickly realised that something was quite off with Subaru and suggested they go back to the place where he worked at to check if he was feeling okay, but before anything else could be said, Subaru commanded Shaula to kill him. She used her Hell's Snipe ability to burn off Regin's head, killing him instantly. After they hid his corpse, Subaru returned back to the Pleiades Watchtower to read his book of the dead.

Meanwhile, a short time after this, Echidna (Artificial Spirit), who had been allowed to escape from the tower by Subaru, made it back to Priestella. She revealed to the members present there that she was not Anastasia Hoshin anymore, and what had transpired back at the tower. Some of the members hearing this report don't believe her, but most of them do. After this, Echidna went to talk to Ricardo Welkin, who now had a metal claw-like appendage in place of his lost arm, about her future, and how she would stop impersonating Anastasia. As they talked, the city of Pristella was flooded by Subaru and both of them perished.

After the watergates were opened in Pristella, Otto Suwen and Garfiel Tinsel both survived the initial flooding. Suddenly, beams of light poured down upon them. With great difficulty, Garfiel managed to deflect them with his shields. Subaru finally arrived at the scene, and confronted the two, and had Shaula kill Garfiel, despite the latter still not believing that his former master had gone insane.

Otto is quick to understand what had happened, and tried to distract Subaru by telling him he should have sprung a surprise attack on Reinhard van Astrea first. Subaru shook his head at that notion and said that the reason he had flooded Priestella was to kill Otto himself. Everyone else was just a bonus. Subaru understood that it would take immaculate planning to even stand a chance at defeating Reinhard. As if affirming that, the hallucinations of some of the people he had killed affirmed Subaru's plan to himself, naming Otto as the most troublesome one. After that, Otto is killed by Shaula.

Shortly after Otto's death, Reinhard confronted Subaru and gloomily asked why he was doing this. Shaula immediately commented that Reinhard gave a very Reid Astrea-like impression, grasping his immense strength immediately. Subaru had come planned for this confrontation however, and he got Shaula to cast one of her Hell's Snipe towards the shelter which Felt was staying at. This allowed Shaula to pick Subaru up and escape with him from Priestella.

Later on, after having once again visited the Pleiades Tower to read everyone he had killed's books of the dead, Subaru continued with his journey to cobble himself together to get back the old "Natsuki Subaru".

Returning back to the events after Subaru had left Amyu alive, Reinhard found the girl alive and well, though shaken. Amyu had been left behind by Subaru to delay Reinhard, who was following his trail.

Meanwhile, Subaru was talking elsewhere with Shaula. He mentioned that eventually he will have to kill Reinhard or it would be impossible to cobble himself back together. And finally, after Reinhard would be killed, Shaula would have to be the last one to die. Shaula was extremely happy to hear her master say she'd be the last one to die, taking it almost like an "I love you". Subaru was surprised at her loyalty, and asked her why she kept on doing his bidding despite knowing she'd die, and she simply replied that it was because she loved her master. Subaru's plan was that after he gathered together all the pieces, he would die and fix things with everyone after he Returned by Death and got back his old self.

The scene ended on a reflection that the pieces that would need to be cobbled together were too many, and that even if he pieced them all back together his new form would not really understand his original one.

Re: Natsuki Rem Life in Another World From Zero
Contrary to all other What IF stories, the Natsuki Rem/Sloth IF was adapted into an entire novel. Occasionally, on Ram and Rem's birthday, the author releases a continuation for the What IF story.

The story is about what would have happened if Natsuki Subaru and Rem ran away from the Kingdom of Lugnica and abandoned everything behind in the third arc.
