It's finally back! seriously, the anime took a weird turn, so I kinda dropped the last 2 episodes. Now, I'm glad because the manga stays the same as novel.
UTOON its always the worse then shit UTOON that just has to ruin series with their disgusting shit translation and censorship.
And for reasons i cant even begin to comprehend, idiots everwhere thank them for their worthless shit.
