Due to quality reasons the Anime will come back in September.
The official website of the Anime of Regalia: The three sacred treasures has announced that after the episode 4 the anime will halt it´s broadcasting and streaming and will come back in September starting from chapter 1.
The reasons, according to the website, is because of a“recognizable difference between the show’s planned quality [and the current quality].”and because of that they decided to instead of cancelling the production will adjust the structure in order to attain a quality product.
While i don´t want to implied that the work they have done is bad (haven´t watched it so i can´t judge) there is a saying in the spanish speaking language that says : “The Lazy person works twice”; in any case the best of luck relaunching the anime!
