New chapters release in Japan 3 times a year. That's it. We're now up to date and waiting for the next Emerald magazine release. This chapter was 61 pages. Normal series are between 20-25 pages, so it takes 2-3 times as long to work on it and provide a good quality scanlation.
I wish this manga could go a bit faster in the aspect of the new chapter releases :( i feel like its been 5 months till i read a new chapter ╥﹏╥
