I'll be honest I couldn't think of a good name for it so this will do if you can think of another one then you can choose the story name but anyways let's get on with it

So our main character was powerless he had no quirk semblance or sacred gear but what he did have was a IQ level bigger than Nezu which wasn't a quirk so no one thought much of him at all not even the headmaster's not even Nezu even though his IQ is lower than his own

He's always trying to be friendly but he still gets beaten up for no reason he has also asked multiple girls I wish they turned them down in a terrible way even Izumi which turns him down but not in a horrible way she just said that she likes back a girl which he's probably only using her to get her quirk

So anyways one day he finally had enough he heard the headmaster talking about how they're going to have a find a way to leave the Academy Awards expelled

This was the final straw he started to make these things called murder is wrong and they were created to kill corrupted humans devils anything corrupted really there are all the workers also work together with the murder drones because they were made by the same guy

But anyways so they were actually sent into a fight the first drone or person he ever created was Cyn/The absolute solver

And our main character was best friends with Tessa which her family is one of the reasons why union is actually standing since her family is one of the biggest supporters or money people that give them money that like about 20% of their income is because of them and losing them would be a big lose

And yeah she sort of joined in on this plan thinking that perhaps it's best if they are pretty much die Alyssa corrupted one so after that happened whenever let's just say all the female drums woke up or after they were crazy that they instantly knew what love was because well they fell in love with our main character there Creator

So Cyn also helped creating the drones and her absolute Solver or elderlitch form and yeah so perhaps that used Tessa's mansion as a hideout pretty much because that place was a Bandan a long time ago

So anyways the drones he created was all of the drones from the actual thing although some of them are implanted with the absolute solver perhaps even including the ones that usually don't actually have that like Lizzie for example

So anyways the workers are the ones who get the materials for new weaponry and to make more drones

So our main character was sort of in The battle area and the people in front of him was talking crap and he decided to talk crap back and there's me the red dragon emperor mad so just so you know the weapons the murder drones were actually coded and was made out of an angelic holy water and pretty much blessed by the guards themselves sort of so it pretty much kills a demon instantly just by getting touched by it

But anyways so One a random student sort of went to try and kill him or attack him and when he got there there was a huge smoke thing that happened and whenever the smoke cleared they saw our main character still in one piece with his eyes closed smiling and they looked up in the sky and saw many three people holding the head and the body of the person perhaps the demon and they just dropped it and smiled and giggled and started to kill everyone around them and perhaps or also civilians in the stands who they also killed because they're able to tell all their sins by their monitor

And some of the head masters tried to help but it was useless sirzech almost died by one strike if he was just a normal demon the attack that hit him would've killed him instantly he knows that these things are corroded and holy water

And they're biting back with blood lust in their eyes but they were fighting and they were winning and let's just say the red dragon emperor try to fight back mainly because of his ego and he can make these girls a part of his harem That's whenever the absolute solver showed up and her drawn form with a maid outfit and sent him far back flying ants he tried to knock her out because making her part of his harem either by force or something

Let's just say she knows who the red dragon emperor is because like I know they don't really have a long history but let's just say they talked in her mind the red Dragon Emperor and her both of them talked and said that I'm going to get you out of that body and create you a new one where you can actually control it and your powers she admits that he likes I mean she admits she likes the idea

So after he was slashed in the side with a blade from a murder drummer that played belong to N which he transformed into his job like not Jugrnaut drive but I forgot the name but it's in his armor he grabbed her and lifted her up and said you will join my hair one way or the other she was still smiling and he was shot in the legs hitting a little bit of his body with a railgun disintegrating his leg and a part of his side or perhaps he loot losses reproductive organ in the process which is the worst thing to happen to him

So what happens next is He was screaming out in pain and that's whenever everyone knew they had to go like over 80% of the civilians that was in the arena stance watching they thought they were going to be completely safe and fine like 80 or 90% of them died and they saw how the drums were drinking their glad it seems like they even got powered up because of it kind of like a boosted gear is that what they're made from they were questioning

So after that rest of the squad drop down and she took the arm or they took the arm with them leaving the human/demon arm on the ground and they were taking it back to make it into a drone pretty much or the soul of the person into it

He was smiling because this plant succeeded they went through a portal which CYN made because she can like pretty much have rewrite reality or control it or something

Also our main character was holding her bridal style because she enjoys being held like that and she's like the most adorable drone there even though she's the most dangerous drone she's still the most adorable

So he was having like a heart attack and all the other drones were because of her cuteness also Tessa was there who also sliced up many of the students there that was trying to attack her

She says that was a mission well done and they also looked at Cyn once again all the Jones even Tessa her self is thick but they were all like she was the most adorable Cyn they just couldn't help but also hold her into a group hug because like she knows she's adorable and she takes she later on like at first she didn't really like it but later on she realized she enjoys it and takes pride in it even though there are some situations where she doesn't act so adorable

The second in line it would have to go to N She's also adorable

And ever since then perhaps the workers replaced the humans pretty much basically that's what happened they're now hiding pretty much because they can't go out alone although the murder drones can actually be outside though they don't have a cooling system that pretty much kills them if they don't drink blood or oil

That's it for now

So the harem is
Uzi
V
J
Fem N
Lizzie
Doll
Nori
Yeva
Cyn
Tessa
Maybe Tessa's mom

Also I just wanted to tell you that Nori and Khan are like mother and father figures to her even if they're not dating at all she still considers them father and mother figures
