At chapter 513 it took way too long to get releases, I got frustrated and went to read the light novel, man I'm so glad I quitted then and there, everything after that in this manga was deplorable and I didn't even read it, I was just checking where the Manga was, and the I started seeing massive skips, like, 100-200 chapters from one release to the next, we'll, I'm glad it's over, if they make a anime, I hope they do it right.
