During Re: Zero kara Hajimeru Isekai Seikatsu (Re: ZERO -Starting Life in Another World-)‘s 10th-anniversary celebration on April 19, 2022, author Tappei Nagatsuki revealed in a Q&A that the story will have a “happy ending”.

During the Q&A on Twitter Space, user @Ame76986079, had asked the author whether characters Subaru and Emilia would end up being married to each other.

To which he replied, “Ame-san, about Subaru, I can’t tell right now. But rest assured it (Re: Zero) will have a happy ending.”

A Twitter user Stride Vollachia(@LoremIpsumVerb) also recorded the audio cut of the moment as proof where the author reassures his fans about the final outcome of Re: Zero‘s story.

This was the original question: this is not to be confused with another question, regarding branching points, which I might do a trivia about in the future. pic.twitter.com/j9IrsvdfRi
