Furthermore, Subaru soon entangles himself in a deadly conflict, unintentionally siding himself, Rem and Louis with the former 77th Emperor of the Vollachia Empire–Vincent Abellux, who asks Subaru to assist him in his campaign to regain the Imperial throne. However, as the Emperor is a wanted man, Subaru constantly needs to watch his back for the assassins and the Imperial Army who wants both Vincent's and Subaru's heads.
The Re:Zero IF chapters are web novel chapters posted each April Fools'. To celebrate Natsuki Subaru's birthday, the author writes a chapter or chapters which deviate from the original web novel. They are around four times longer than normal chapters and show what would've happened if Subaru did something contrary from what he actually did. Each of the chapters resembles one of the seven deadly sins.
Currently, only one Web Novel chapter has been removed from the Web Novel, which is the Butterfly's Dream What IF Story.
According to the author, there will be eleven arcs, though he originally planned for nine, with Arc 2 and an unknown Arc being added later.
The Web Novel does not feature any illustrations except for the End of Sloth chapter in Arc 3 (chapter 80).
Arc 6 is the Arc that was being written for the longest time. As opposed to every other Arc beforehand, Arc 6 took Tappei roughly 5 years to complete.
In a Re:Zero Talkshow held back in 2018, Tappei Nagatsuki expressed his desire to name the final Re:Zero chapter Re：ゼロから始めた異世界生活 (Re:Zero − Having Started Life in Another World).
↑"Arc 2 itself was something I added because it wasn't in the plan. If it wasn't for that, there would have been nine Arcs. Now there's one more Arc, and it's going to be 11 Arcs."Tweet reply.
