Johan character is only hyped character with no detailed explanation that how he did all things. You can call it empty hype , like if someone say he did this and that etc etc but with no explanation "how ?"

Johan is my favourite character in anime,I love monster but I was expecting in story that writter would give all detailed explanation that how those all things were done by johan but he didn't....

Only a small scene were shown that how he manipulate that detective and nothing else was explained Like: how he made all children to kill each other at age of 10 How he control all black /dark market at 15 age How he creates all his team / group/ puppets to do work for him What he told them and how and why they listened to a young guy ? There is no detailed explanation

All writer did was telling us that he did this ,he did this , he controlled all, etc etc and not anything else explanation It called fake hype But I like the way he put all those things without explanation But I was expecting explanation of all those hyped things which Johan did

So I was expecting more in the final episodes but it didn't reach to my expectations....
