Tl:dr fuck you author
First of all let me say that this manga ain't trash, writer is actually put quite an effort to the story.
Human use martial art with tools, demon use magic. The moment mc had access to human weapons the results of his training immediately appear.
He used 'guard' against huge cobra without shield, then it is mentioned that he was using bracers in side story
Village chief explained that 'sting' can hit target across village, that means human could snipe enemies, so how did demons survive?, they must be equally powerful = strong demon can cast magic nukes. But the bomb experiment deny this. I'll assume the projectile won't have enough power to kill at long range (humans have to be nerfed, with exception to MC ofc)
Next, melee fighters have to have a way to close range hence movement abilities he use made sense, demons should be able to use say wind magic to offset this which is not strange.
Mc as wise advisor is well known in demon world even to the king, prideful military officer that wants glory is the cause of him getting fired.
He is kind, far too kind for a war strategist. he doesn't hate human, how? because deep down he wants peace. He planned all that war stratagem purely because of work.
Which is impossible, author knew this as shown in latest chapter (9). But nevertheless, he made it that way
"cmon guys can we settle with this" I can hear him answering my questions as i read the manga. "this is comedy manga yknow, please?" he continued
He explained how mc superpower make sense.
"where is the strong humans then?" I asked
"there's this strong female but she's afraid of monsters, unfortunately.... But they are there somewhere!, see that heavenly wind God loses to human army?. It's there!"
"then why are demon knights in the mine that weak? They are soldiers, they fight with strong humans thus should be able to do better, more resourceful than casting spell slowly while standing still like peasants"
"those ones are fighting on front lines, there's only little devils in the mines so the army sent rookies"
"you're bullshitting me"
"listen, my light hearted manga send message of peace to people, look at my MC he wants to save everyone and that is how things will unfold . You readers all wants bloodshed shame on you."
His spit touchesmy face, dormant emotion within me exploded
"ARE YOU FOR REAL, IF HE WANTS PEACE THERE'S COUNTLESS MORE EFFECTIVE WAY TO DO IT, HE HAS THE POWER TO MAKE IT POSSIBLE" I shouted
"THOSE MIRTHIL WOULD BE MADE WEAPON TO FUEL YET ANOTHER LIFE-TAKING BATTLE"
"MIRTHIL AIN'T ONLY USED TO BUILD WEAPON" he shouted back "THE POINT IS, MIRTHIL IS A USEFUL METAL, READ BETWEEN THE LINES YOU CUNT" ( D: )
"stop talking" I facepalming hard "this is so stupid"
"it won't be a manga for everyone dear reader. The publisher I worked on has age target, I... need to eat"
"....fine, sorry dude. it's just... " I gulped, trying to say the sentence I always try to avoid "it's just a story"
I turned my back and leave him, gritting my teeth. "fuck you author" my voice comes out softly, without anyone around to hear
