A brief description of the manga A Brave Man Trained by the Worst Demon King, Unrivaled in the School of Returnees from Another World:
Without possessing the unique skill blessed by the goddess, a boy named Kujou Kyouya failed to save the world. He was ridiculed as a “failed hero” at the interdimensional-level academy where returned heroes who had saved many worlds gathered.
However, he became the strongest and most unique hero, having trained for 30,000 years in another world with the most evil demon king, Felice, who has destroyed 3,000 worlds!
Now Kyouya’s unique skill is so powerful that he cannot even be defeated by the strongest heroes! The legend of a boy trained by the most evil demon king, begins!
i’ll give it another chance at a later date i got bored after like 8 chapter another story where the mc hides his power like wtf
Rating tjis higher than 2 stars is an offense to the industry
3/5
They should’ve added “shounen” tag to this, the story isn’t bad, but it’s another generic OP MC hiding his power, added with useless naive side chars around him, MC was naive too btw…world building had potential but it was too tiny and illogical… Why would every single one of the so called “heroes” with strong powers obeyed to be “trapped” in a silly school? Doesn’t make any sense for me…
I actually rather like it.
Premise was interesting, but I got bored after 4 chapters. Kinda rubs me the wrong way. 3/5, just for trying.
After reading 13 chapters I am trying to figure the generic of this story. More then likely a so called hero who is op, tried hard to hide his power as the nail that sticks up gets hammered and cut down … hard, so they hide it or try to. This is the same as Bang and Huang mentioned earlier. Now if that was all it was it would be a boring read. The support characters are pretty decently done to compliment the story. The story also moves along at a fast enough pace that it doesn’t give the feeling of bogging down. Of course the big baddies that are to turn up are other heroes who have gone “rogue” or who have lusted after power and where trained by the demon lord like he was. Then there is a big baddie who is due to turn up somewhere down the track cause it threatens the worlds tree in some way, at lest the feeling I get. But the twist I liked and hasn’t been done often is, to be trained by the biggest and baddest assed demon lord (fall in love and converts … cliché?), then goes to the goddesses hero school to have a normal life and not end up in the same scenario as that said demon lord and be sealed away for hundreds of thousands upon hundreds of thousands of years times tens of thousands of years. But I have often said, until 20 to 30 chapters in, you don’t really see if the writer can employ their talent to this storyline and you cant know if it all comes together as a manga till at lest chapter 100.
I WANT MORE CHAPTEEEEEEEEEERS
im gonna be honest ill have to wait until this gets like 20-25+ chapters otherwise ill finish it too fast 
Another pathetic overpowered hero only finding the resolve to fight after watching everyone around him fail/die because he doesn’t want to be recognised as strong
7.4/10
Read: 11/?
Bookmarked? Yes.
Generic. A word that describes many hero mangas. The plot’s predictable along with the characteristics of the overpowered main character. However, making up for the lack of’s, the side characters are surprisingly well-developed and aren’t obnoxiously inserted…most of the time. There’s not much to say about this manga as it doesn’t have much weighing it down but also not much going for it. It’s a fun read plotting from its concept, but that’s all it is.
