When Izuku and Ochaco sat down on the bus a couple of minutes later it was moving and Ochaco turned to Izuku and asked ''so Izuku what was the thing with the sword''

With a little sigh Izuku said ''I might as well tell you as I get the feeling, we will be great friends and hopefully something more though if we do become more there will be others''

''wait you mean to tell me that you will have more then one girlfriend'' Ochaco said with a blush because Izuku was hoping to become more then friends

''yes, I will have more than one mate'' Izuku said then went on to say ''anyway about the sword it is to do with my quirk at the moment I know of four aspects of my quirk and each one of them is powerful on their own but they each have their own weaknesses one can't swim because he ate a fruit known as a devil fruit and his name is Monkey D Luffy''

''what's a devil fruit'' Ochaco asked

''to simply put its a fruit, you eat to gain a quirk, but it doesn't get passed on when you have kids and when you die it goes into another fruit for someone to eat but it takes away your ability to swim'' Izuku said

''I think I get it'' Ochaco said

''now with the sword it belongs to another aspect called Inuyasha and he is a hanyou of a dog hence the ears and tail though the tail is actually from a another aspect who has a monkey's tail but as the demon aspect was stronger, I gained a dog's tail and not the monkey one'' Izuku said

''that sounds so cool'' Ochaco said

''anyway, as the demons blood in Inuyasha is powerful even for him another demon called Totosai a demon blacksmith placed a seal on Inuyasha's sword then Tensaiga to keep his demonic blood in check'' Izuku said

''I get it now not only do you gain all the power that the aspects of your quirk has but also their weaknesses as well'' Ochaco said finally understanding

''current Ochaco so if Tensaiga is taken or I go a far away from it then the demonic blood that I gained from Inuyasha with go rampart and its happened once before about five months ago'' Izuku said

Then the two began to chat even though it was mostly Izuku giving advice to Ochaco and telling her that she has great potential when suddenly a voice of the strict person that called him out when Izuku was talking to his quirk ''hey this isn't the time to be flirting we are here to become heroes not to pick up dates''

Izuku gets up and grabs the guy by this collar and said while emitting a little bit of his conquerors Haki not too much bit just enough to be a bit intimidating causing the guy to sweat a little ''now you listen unlike my sister who will try and talk thing out I won't as I could be classed as a proper demon so do forgive me if I don't met your expectations even though I don't give a shit what you think and also me and Ochaco know that we are here to become heroes and tensions are high enough so why don't you do everyone here on this bus a favour sit down and shut the fuck up and let us do what we think will lower the tension'' then lets go and sits down before he stopped emitting his Haki

When everyone saw Izuku was talking to Ochaco a single thought went though their minds ''don't piss of that guy''

''that was cool what did you do to get that guy to sweat that much'' Ochaco asked

''Ohh nothing much just gave him a blast of my conquerors Haki'' Izuku said

''what's that'' Ochaco asked

''well haki is a mysterious power that allows the user to utilize their own spiritual energy for various purposes and there are three types of haki two of them can be taught to anyone and everyone and they are observation haki which grants you a sixth sense then we have armament haki which you can coat yourself and anything that you are holding in some kind of black substance that is a lot harder than steel which and be used for offensive and defensive and lastly we have conquerors haki as it is the most powerful of the three as it grants the user the ability to overpower the will of others and this results in victims being mentally overwhelmed by the user'' Izuku said

''wow that sounds like a cool ability to have'' Ochaco said then asked ''so which aspect does that come from''

''I get the Haki from Luffy'' Izuku said

''hey aren't you scared that someone will get have a better chance to beat you'' Ochaco asked

''let them try after all I never mention the other two aspects and one of them can be pretty competitive'' Izuku said

Then the bus stopped and the driver said ''alright trainees we have arrived at battle centre B so get of the bus''

When everyone was of the bus they all went to the door and wait for the doors to open and he was standing next to Ochaco when the doors opened and Izuku heard all four aspects shout out ''hey get moving'' and just before he did he gave Ochaco a nudge causing her to look at Izuku who gave her another nudge then with amazing speed he run into the battle centre

After a second Ochaco knew what he was telling her then steeling herself then she run into the centre determine to become the hero that Izuku sees her becoming

Everyone else looked at the two run in and one of the participants said ''hey nobody said start''

On top of the gates President Mic said ''hey what are you all waiting for its already started get moving'' and everyone started to run in the battle centre

The test was almost over and Izuku had been taking it slow and attacking any and all robot that crossed him and he didn't even know how many points all that mattered to him was he was having fun thanks to Goku when he heard ''alright trainees you have two minutes left'' then the ground began to shake then a robot that was as big as the average size building stood up and started to rampage causing mass panic

Few minutes earlier

Up in the observation room the faculty heroes was watching the exams when one that was dressed like a dominatrix said ''we have quite a batch this year don't we''

''that we do Midnight that we do'' All Might said

''so what was the reason that Hizashi told the kids that they might lose three quarters of their point if they fight the zero pointer'' Midnight asked

''its to see if anyone knows what it means to be a hero'' Nezu asid

''right'' All Might said then Hizashi made the participants only have a few minutes left then All Might said ''and the real test start now'' then he pushed a button

Back in the battle centre B

Izuku was walking calmly thinking if he has enough points to pass when he heard a female ''ouch'' so when he looked, he saw Ochaco trapped under a bit of debris

So doing what was right he walked over towards to her even though he was sure why he had such strong desire to walk when everyone started to slow down then saw some kind black vaper coming from everyone then he heard ''so you are the Kami told us about'' then he looked to the left and saw an average young man with red eyes and greenish black hair wearing a red shirt and black trousers that looking like a fast-food uniform

''so are you another aspect from the quirk that Kami gave me'' Izuku said

''I am and the name is Sadao Maou'' said the now identified aspect

''well judging by you name I would say you was a demon'' Izuku said then asked ''so is there a reason why I can see you and not the others''

''yes about that well it appears that you weren't strong enough to see us and now you don't ask me why I don't know and nor the others any way we all can figure that out later'' Sadao said then went on to say ''and yes you are right I was a demon but not an ordinary one I was a king but lost my powers when I fled my world but that is a story for another time and the only way to get it back is though intense negative emotion and that's what the black vaper it its intense negative emotion''

''that's good to know'' Izuku said ''Sadao as there isn't time for you to train me in you powers so until the zero pointer is done I am letting you have control over my body'' and when Sadao nodded Izuku closed his eyes then felt a tug that indicated that Sadao had taken over then the intense negative emotion headed to Izuku then surrounded Izuku but to others it was like he was surrounded by an egg like tornado then when it disperse there stood a humanoid demon that stands over three meters tall with sharp red eyes and really messy green hair he has well-built bod, he possesses several features that are decidedly more demonic, including sharp-clawed hands, a pair of yellow ridged horns that curve outwards from beneath even though one was missing and large furry goat-like legs ending in thick hooves. Satan also possesses two large bat-like wings then he started to fly up then he disappeared then reappeared in front of the robot then brought an arm back like he was going to punch then a few red circles appeared then he punched the zero pointer which was completely destroyed then once he was on the ground he started to lift up all the debris and repaired all the buildings after that he healed all the wounded once that was done he used up to much of the new power he turned back to normal then fainted but just before his world went completely dark he heard President Mic say ''and the test is now officially over''

The buy the book person was wandering what happen ''who is this guy he didn't even hesitate to fight the robot even though he will lose most of his points why if this wasn't an exam then I would do the something'' then he realised something 'wait the exam the judges they saw everything''

''very nice all of you and everyone of you are all heroes in my eyes'' Chiyo said then gave some kid some gummies then walked over to Izuku and said ''now what happened to you Izuku''

Ochaco walks over and said ''um Recovery girl I don't know what happened but what I do know is that Izuku looked more demon'' then she began to describe what Izuku looked like and what happened

Chiyo looks likes she was thinking then said ''looks like he has another aspect and judging by what you describe I would say it would be a demon all well'' then looks around and asked ''so who is hurt''

Ochaco said ''no one is hurt Izuku healed us all after he but the buildings back together also why arnt you checking to see if his alright''

''that because I already know what wrong with him'' Chiyo said

The by the book person walk up and said ''so Recovery Girl what the reason why he just fainted like that''

''his just exhausted he hasn't had time to adjust to the new aspect and its power though I am sure his mother won't be happy that her son used the new aspect without letting his body adjust first so which one of you want to help me get him to the sick bay''

Ochaco said ''I will my quirk can cancel gravity''

''Ohh that's good can you take him I need to go to the other sites'' Chiyo said

''sure'' Ochaco said as she walks over to Izuku then touched him to make him float then headed to the nurse's office with him

When Ochaco got to the nurse's office she opened the door and saw Inko looking up and she said ''well hello dear what are you here''

''Ohh it not for me if for him'' Ochaco said then pulls Izuku in sight of his mother

When Inko saw her son she said ''Izuku'' then she rushed over asking the girl ''what happen to him'' then Ochaco began to explain what happened once she was done Inko sighed and said ''out of all the time an aspect decides to awaken it had to be then well put him on a bed then if you want to can you get my daughter she should be waiting for Izuku by the main gate you can go home'' and Ochaco did as told

After about an hour Izuku woke and said ''what happened''

''don't you remember'' Sadao said who was leaning agents a wall

''give me a moment it might come back after all I am sure you have had moments like this'' Izuku said then he started to remember what happened at the centre then said ''mums going to kill me''

''why is that'' Sadao asked

''because I used a power that my body wasn't used to and that took it tole on me which caused me to faint like that'' Izuku said

''I see we I wouldn't know as my parents was killed when I was a boy which caused me to have the drive to become the demon king cause I wasn't born royalty I was actually born as a low ranking demon'' Sadao said then went on to tell Izuku some of his past and what his power is

''so what's the drawback'' Izuku asked

''the drawback is you can only gain the magic if there is a massive intense negative in the immediate area as it doesn't regenerate by itself'' Sadao said

''let me get this straight I am able to use magic but the MP I need to use it won't regenerate by itself however if there is huge amount of intense negative emotion around me I can use it to regenerate the magic and if I have enough I can become you demonic form'' Izuku said

''yeah sounds about right'' Sadao said

Before Izuku could say anything else he heard his mother asked ''talking to the new aspect dear'' causing Izuku to look over and see his mother Nezu Chiyo and Toshinori standing at the doorway

''yes I was and it's a demonic one named Sadao Maou who can use magic but the downside is the magic cant regenerate by itself'' Izuku said

''so Izuku how does it regenerate'' Nezu asked

Izuku looked down a little and said ''when there is a huge amount of intense negative emotion''

''I see so when everyone started to panic in your test site you gained some magic and used it to obliterate the zero pointer'' Nezu said

''well your half right Sir I did get a bit of magic there but as there wasn't time for Sadao to teach me one or two thing that comes with his bower so I let him take over my body and he deals with it'' Izuku said

''I see well Izuku I hope you will be coming here to train with the magic you have to you don't accidentally destroy something'' Nezu asked

''was kinda hoping you would let me sir'' Izuku said

''how can I say noy when your aspect completely destroyed a robot I fear that until you have some control that power you will destroy more than a wall or two'' Nezu said then said ''now go home and celebrate you and you sister did well and we will sent you results to you in the mail and I will see you here tomorrow with your mother''

''you can go as well Inko go home and be with your kids'' Chiyo said then the mother and

Not long after the mother and son left when Shota came in and said ''sir I request to have Shinso Hitoshi in my class''

''may I ask why'' Nezu asked

''well Izumi was outside waiting for her brother I was heading there to tell her that he was on the infirmary because of an aspect awaking however when I got there I heard some kids saying that the green-heired boy was a fool for taking on the zero pointer knowing that he will lose his points and that he was a demon Izumi who knows about Izuku's quirk and that there might be more aspects somehow knew that the boy was talking about her brother got up into his face when miss Uraraka came over and somehow talked Izumi out from beating the guy they was heading to the infirmary when the guy didn't like it and was about to attack Izumi but Shinso stopped it then the guy walked home like he was in a trance so I did some research and found out his quirk was useless in the exam'' Shota explained then hands over Shinso's folder

Nezu reads it and said ''I see what you mean Shota that his quirk can't be used in the exam but he doesn't have the physical prowess one need to be a hero''

''then let me train him and get him ready'' Shota said

''I might allow it but only if you answer me honestly do you think he can get him ready for the start of term''

''I might if I have All might make up a plan for him'' Shota replied honestly

''very well I will allow it but on two condition'' Nezu said

''and what are they'' Shota asked

''you don't expel the students on the first week you can threaten them with it but don't follow through with it'' Nezu said

''fine and the other'' Shota said

'he must be placed on any position other then last otherwise he be placed in general understood'' Nezu said

''yes sir'' Shota said then turn to leave

''Ohh one more thing you will be doing the kids hologram to explain what's going on'' Nezu said

''understood sir'' Shota said as he left the headed to the message room

Rules for quirk only one they must have something that effects their body in some way or form like a curse though eating a devil fruit (one piece) or fulling into a cursed spring (Ranma ½) or biology like Inuyasha losing powers or going berserk (Inuyasha) you Saiyans being weremonkeys (dragon ball series) so nothing like escanor (Seven Deadly Sins) Yuna (Kuma, Kuma, Kuma bear) Rimuru (that time I got reincarnated as a slime)
