If there's one event that still divides the Mushoku Tensei fandom to this day, it's the relationship between Ars Greyrat and Aisha Greyrat. Ars is the son of Rudeus Greyrat and Eris Boreas Greyrat, while Aisha is Rudeus's half-sister, making her Ars's aunt in the family tree. As the years passed, the two developed romantic feelings for each other despite their age difference, and their relationship eventually became a full-fledged romance in the Redundancy stories. When Rudeus discovered the relationship, he was deeply shocked and furious. It completely conflicted with his personal values, and the situation was made even more complicated by the fact that Aisha had helped raise Ars since he was a child. The entire Greyrat family was forced to confront the issue, making it one of the most difficult family crises they had ever faced. Interestingly, the controversy wasn't limited to readers—it reached the author himself. The story sparked such a strong backlash that Rifujin na Magonote removed the Redundancy chapter covering their relationship from the web novel. He later stated that if these events were ever published in an official release, he would rewrite or significantly revise them to better match his final vision for the series. Because of this, the details of their relationship in the web novel should not be considered definitive canon, as the author himself has acknowledged that they are subject to change. As for Ars, the main novel doesn't highlight many major accomplishments of his. He inherited his mother Eris's exceptional talent with the sword and grew up surrounded by some of the world's strongest warriors and mages, but his appearances remain limited. As a result, most readers remember him not for his strength or battles, but for this highly controversial storyline. In the end, Ars Greyrat became a character remembered less for his achievements and more for one of the most divisive and debated stories in the entire Mushoku Tensei series. #MushokuTensei #ArsGreyrat #AishaGreyrat #LightNovel #AnimeSpoilers
