@feha could of learned from him from his previous master

Also doubt his master was the demon king but likely a demon dark mage

I wonder what hes true power is we see him with horns so wonder he can activate a demon mode

Spoiler

His master/adopted father's name is "Lucifer".
Guess who?

 

[Astraea]

Where do i read the raws ?

 

[PhoenixStriker5251]

@Astraea
I haven't been able to find the manga raws, but I have the novel raws.
https://ncode.syosetu.com/n4836fm/

Chapters are up to 234.

 

[siralbert]

Did anyone translate the novel? I'm having trouble finding it on novelupdates, but that could as easily be because of the ridiculous name, as because it wasn't translated.
@PhoenixStriker5251 Hey Phoenix, I'm just tagging you because it seemed like you knew something more about the plot and might be able to help.

 

[entity_101]

@Starbright I think the horns he has is probably some sort of cosmetic than "demon mode" so that he can pass as a demon or something because as far as his explanation goes, and considering the fact that it was revealed that he learned from a demon, I think that he's pretty much at full power, the thing is that nobody can notice his power since he's a debuff-specialist, and since he doesn't want to reveal the identity of his master then he can't explain nor use his powers against a human because his master identity would be busted, something that he doesn't want to happen

 

[neo_child]

@FgoSegul I think his power is absurdly strong but, as said, black mage powers aren't readily available.

Who knows how much debuffs he's been casting on the enemies. How much armor, evasion, damage of the enemy has he debuffed? How many times has he saved his team from doom by breaking up difficult enemy formations with confusion and berserk spells? It'll be sweet karma once we see that their team stops pushing as fast as they have been.

 

[DailyBacka3]

Yooo did you saw he boobs

 

[pingustrategist]

Wait... If they were really close friends, then his friend would have left with him.

 

[theowww]

so his master is maou himself, that's explain why he hold back very much and swallow the bitter humiliation. while waiting for next chapter, i want to sing. the long and winding rooaad...

 

[kaminomikan]

insert hello police.gif.

 

[regalia001]

well now just wait for his party to get quack as they are facing demon with the "Oh, It's not even my final form yet"

 

[SoloSera]

No novelupdates link, huh? I really like debuffs, so I really want to read more of this.

Thanks for the translation!

 

[ghostt]

This is so fucking stupid. So this idiot is holding his power back while crying about not being acknowledged. Fucking dumb

 

[Nematoda]

yeah ~!
rather than join party with bunch of mens and disappointing loli, better join party with busty Demon Onee-san ~



@ghostt it seems you didn't read previous chapter, he said it himself that if he do that, he gonna expose the Demon who teach him, since it seems his black magic is 'different' than usual black magic, probably because its come from Demon magic...
he at least keep the promise he made with his teacher rather than broke it because some scumbag insulting him...
he want people acknowledged that Black mages is not useless, by joining Demon army and disguise as Demon (from the cover, he has horn) then he can show the world how Black Magics works, since he's "Demon", using Demon "Black magic" is no problem for him.

 

[Kuri_Something]

Thanks for the chappy!

hold up, so if his master isn't the Demon King, who is it? I’m going off the idea that the Demon Kind’d be the most powerful demon, and if they needed his support, who the hell taught him black magic?

@siralbert
No official translation unfortunately; I used a machine translator.

No idea how accurate the following is, but:

Spoiler

MC is WAY more powerful than he appears here.
(Powerful as in a melee-battle mage that can freely resummon the other floor bosses at will as well as take on that asshole swordsman himself 1v1)
MC has the ability to turn into a one-horned devil, as a result of something Lucifer did.
In the war brought about in the previous Demon Lord's reign, the Demon Lord (Lucifer) used dark magics so powerful that he annihilated top adventurer parties single-handedly. (Heck, a veteran member of the Rank 1 party straight up invites Rene to join them when he came near Rene and felt a similar sensation to back then.)
It is implied that the government and media are suppressing knowledge about the true strength of dark magic.

The Flame hero (Mc's best friend) was bullied in the past for his dream of becoming a hero, but MC continued to support him even when he (the friend) eventually did get the hero class.
The demon girl in this chapter is presumably either the "demon of love" or the vampire queen, two of MC's future comrades.
As a demon, Rene goes by the name of "Remegeton" or something like that.
After he joins the demons, Rene lives a double life as "Remegeton" (the 10th floor boss and dungeon master) as well as himself, gathering info about upcoming challengers.

The effects of MC's absence in the party quickly becomes apparent, as the other party members seemingly lose proficiency and the viewers wondering if they were "sick" or something.
Only the Flame Hero performs somewhat optimally, due to him being the only to really understand Rene's capabilities (and thus knowing what to expect now that he's gone).

MC does eventually fight his former team. He breaks standard dungeon conventions by resummoning all (or most) of the other floor bosses simultaneously, and he combines his magic with strategic commands to capitalize on his old team's weaknesses.

Spoiler

Ex: He f*cking baited that a-hole swordsman into using his extending sword, used his enhanced strength to rip the sword straight out of his hands, and then impales the guy with his own sword.

Everything above that I just described?
That was only the first volume.
There are FOUR volumes.

 

[chucke1992]

@PhoenixStriker5251 what I do not understand is that it is still MMO no? I mean game

 

[PhoenixStriker5251]

@chucke1992
Not MMO; real life but with MMO mechanics.
The dungeons/towers have a mechanic that allows people who die inside to respawn, but it seems to work only when INSIDE the towers.

 

[ghostt]

@Nematoda And that’s why it’s fucking stupid. Obviously I read the chapter I just thought it was dumb, he was asked not to tell who his teacher is not hide his magic.
