This manga is still okay and quite acceptable even when we reach chap 300.
But then it hit its bottom right away, i can't understand. Nakaba what have you done? What was really going on?
Anyone notice that Demon King have not even used his “darkness”, his eyes is not dark, he doesn’t active demon mark, so this is just his base form and he dominate all. Just imagine he actives demon mark/2nd demon mark or his assault mode..
