That was a good decision. I watched 31 episodes of it just to realize that it's waste of time. It feels really childish with all that furigana on episode names and stuff. In addition it's not advancing anywhere. Kinda how Hunter x Hunter episodes during the big fight with Meruem took the plot forward so little every time. The only difference is that Hunter x Hunter was actually rather good.
All in all my enjoyment was lower that Osamu's trion level which resulted in me dropping the series.
