The anime indeed has been positively met by the viewers. On MyAnimeList, the series holds a score of 8.51 based on approx. 14,000 votes, and it was included, thereby in the TOP100 most popular anime ever. Yet still, whether there will be another season of Mahoutsukai no Yome?
The question is truly difficult since the short answer is no, there won't be a next season (at least soon) as there is not enough source material. The anime is currently ahead of the original manga series of the same name, excepting only its tenth volume, which has been issued on September 10, 2018.
On the other hand, we need only four more volumes for another anime adaptation. Given the fact that the manga author Kore Yamazaki releases two volumes twice a year, we still have a chance for Season 2.
Mahoutsukai no Yome Season 2 Release Date
As mentioned above, we don't rule out that the Wit Studio is going to renew The Ancient Magus' Bride for a second season as soon as four additional manga volumes are issued. Yet how long might it take? Since Kore Yamazaki produces two volumes per year, we need at least two more years in order to the source material be completed. Next, we will have to wait for at least one more year, while the Wit Studio will be creating another television adaptation of the manga. Finally, someday in 2022 the studio might announce the exact release date for The Ancient Magus' Bride Season 2.
In any case, we won't see the 2nd season in the foreseeable future. So we are tracking down the official sources in order to provide you fresh news. As soon as the Wit Studio announces the renewal, we will update this page. Stay tuned for updates.
