The official Twitter account for Ichijinsha’s Comic Zero Sum magazine has announced that Bunko Matsuura’s manga adaptation of Tenichi and Suzunosuke’s The Most Heretical Last Boss Queen: From Villainess to Savior light novel series has been canceled due to Matsuura’s continued poor health. The announcement added that Ichijinsha plans to continue the manga with a new serialization in some form, but has no concrete plans yet.
Tenichi, the author of the original light novel, also made an announcement regarding the cancellation, thanking Matsuura for their work on the manga, and hoping that the manga creator can recover to make more work in the future.
The series is described as:
Pride Royal Ivy is only eight years old when she realizes that she’s been reincarnated, destined to become the future wicked queen and final boss of an otome game. She’s got it all in this new life: razor-sharp wit, boss-tier powers, and influence over the kingdom as crown princess. Determined to sow despair and destruction across the land, she… Wait, what kind of a rotten future is that? Princess Pride decides to drop the maniacal villainess plan and protect the male love interests instead, cheating her way to saving everyone she can. Will this final boss end up earning the adoration of her kingdom?
Matsuura launched the manga adaptation of The Most Heretical Last Boss Queen: From Villainess to Savior on the Zero-Sum Online website in March 2020. Seven Seas Entertainment is publishing both the original light novels and the manga adaptation in English.
