The Greatest Heroes: Grav and Nemui

Grav rubbed the back of his head from all of the attention, before sighing and beginning, "That second Quirk, Cannibal Virus? It's a weird and frightening Quirk."

Grav explained, "The 'Cannibal' part isn't just from attacking itself... it also attacks from inside my body."

Grav adds, "Not only that, but it comes with a side effect of unleashing my wild side, making me a battle maniac."

Nezu said, "Well we are going to help you control it, as for you Nemui... what is with your family?"
Nemui said, "My parents are the two most notorious villains in America, they got in a marriage to make the most powerful villain in the world, my brother and sister came first. They are twins with mom and dad's quirks which they embraced the whole villainy thing. I came to birth and they trained me a lot more rougher than I can say. The thing about reality is that I forgot what's truly real and what's just something I created. With time... I have seen it all, like a soldier with PTSD, the flashbacks and triggers which I keep to myself. The quirks takes my sanity away from me, which leads people with mind quirks unable to calm me and control me."
Nezu said, "We will give you two treatment, but we would like you two to turn it down a few hundred notches. The fight was too brutal and that is coming from me."

Grav crossed his arms, "We make no promises. This is because we turned to heroes for help, but they just waved us off as lost causes."

Nemui said, "Society has failed us, so we are just free spirits that do what we want."
Nezu kept a straight face which Aizawa was in the room super terrified, Nezu said, "Society may have failed you two. But in this school, we will not fail you and we will help you."

Grav rolled his eyes, "Doubtful. All For One kidnapped me as a newborn, so I have no clue as to where my biological family is. That's one of the minor questions I have."

Nezu nodded, "We can get you a blood drawn to find your family."
Nemui got a milkshake out of a portal and asked, "Grav, you want a milkshake?"
Nezu said, "As for you, we have Hound Dog give you therapy sessions like Grav."
Nemui smirked, "That's going to be fun."

Grav answered Nemui, "Pass. I will, however, have some food from that Shokugeki no Soma universe."

Nemui said, "Can you tell me which one, because there is a lot."
Nezu asked, "Can we get back to the topic?"
Nemui said, "After I get his food."

Grav specified, "Ryo Kiba's Lobster curry."

Nemui grabbed the dish out which they heard, "Hey, where are you..."
Nemui closed the portal before the voice could finish, which Nemui said, "It was in the middle of a competition which means it's the good shit."
Nezu and Aizawa face palmed that Nemui just stole in front of them on a hero school's grounds.

Grav nodded, "I'm off to the cafeteria. Later."

Taking the dish, he left as if it was just a meeting, he didn't want to be in.

Nemui said, "Well I got some mediation I have to do."
Aizawa said, "Wait a minute..."
They disappeared right before their eyes which Nezu said, "They are going to be a problem, but we can still help them."

In the cafeteria...
Grav was digging in, before noticing Mina staring at him. He offered a spoon, "Want to try one?"

Mina smiled, "I would love too!"

Grav handed it over, but paused before turning to Nemui, "Recording this?"

Nemui said, "Yeap!"

Mina gave them a strange look, before taking the spoon and digging in... and had her first taste. Nemui thought to himself, 'I probably to label this as Grav's fap tape because I am not keeping this for... reasons. Grav would love to have this.'

As Mina 'experienced' the taste, Grav was full out laughing at how she reacted. Nemui pushed a few buttons on the camera to say, "It will be sent to your phone Grav."

Grav grinned, "Thanks for the blackmail. And since it looks like Mina will be hogging it... get me a Hiyama Burger."

Nemui pulled out a Hiyama Burger and gave it to Grav. Mina asked, "What is that?"

Grav took a bite before swallowing and answering, "It's sort of a hamburger. It contains kofte, a beef and lamb Turkish 'patty', achaar, and some spices." He took another bite, before asking Mina, "You going to finish the lobster curry dish?"

Mina continued eating the curry which Nemui opened a portal to look at girl he found interesting. Nemui still has ears ready for anything Grav asks for. Izuku asked, "So how did you and Grav meet?"

Grav instantly answers without hesitation, "He met me while I was trying to commit suicide."

Nemui said, "I was insane and thought that I was god because my quirk... well I'm less insane but I have lost the god complex because of him. He told me his story; we may have different experiences, but we shared similar pain."

Grav chuckled sadly, "The sad thing is... I was about to take a swan dive off of a roof and hope for a better Quirk in my next life." Izuku and Bakugo shared a look, noticing how it mirrored Bakugo's 'swan dive' advice.

Nemui said, "We sat and talked for a long while which we helped each other in a lot of ways. We felt like we could open up to someone about our pain and struggles."

Grav then jabbed a thumb at Nemui, "After that, I decided to tag along with him as we toured the multiverse."

Nemui said, "He would help me remember which multiverse was ours and which timeline was our timeline as well. Which we collected many things and met many people and creatures."

Grav interjected as he finished his lunch, "Didn't we have to kill Santa in that one universe?"

Nemui said, "I thought we agreed it was an accident."
Everyone looked at them in shock, "WHAT?!"

Grav countered, "Yeah. And you sniping the Easter Bunny off a cliff, with me watching out for you so that we wouldn't get caught, and feeding the said bunny live to some sharks was an 'accident'."

Nemui chuckled, "Life's happy accidents I tell you what."
Bakugo said, "That is no accident!"

Gray rolled his eyes, "At least I can proudly say that I killed the toothfairy."

Nemui said, "Okay, the toothfairy had to go."
Everyone thought, 'NO THE TOOTHFAIRY DIDN'T NEED TO DIE!'

Grav added, "Wasn't sure about Jack Frost, though..."

Nemui asked, "What did we do to Jack... my memory is pretty vague on that one."

Grav deadpan, "Rise of the Guardians version."

Nemui said, "Oh... OH! Yeah! Anyways we spent a large amount of time in the SCP universe, because some of the SCP we could relate to."
Momo asked, "Could you explain that universe?"

Grav explained, "SCP universes include this assortment of anomalous things. They can range from safe, to world-ending dangerous. Various background, but all are put in specialized containers to keep away from the public."

Nemui said, "There are about 5000 SCPs in the inverse and they are still counting, they range from diseases to teddy bears to reptiles to IKEA stores to God. Which to quiet honest when we met with God in that universe... I was disappointed."
Denki asked, "You were disappointed in God, like the God?"

Grav corrected, "Not quite a biblical god. More like... an entity with god-like abilities."

Nemui said, "Exactly... Why would he be there if he is God? I mean if I were god then I wouldn't be in there."
Nemui opened a portal, "Grav, you want something from the coffee machine?"

Grav instantly spoke, "Death Wish Coffee, my version, for Aizawa-sensei."

Nemui grabbed it to give it to Grav which Nemui when into a portal to say, "I'm going to be talking with 682 for a while, he won't eat me because I am in his words 'Bearable'.

Next Day

Grav, still in his school uniform, was walking to the workshop with Izuku, Uraraka, and Ida. Grav explains to the three, "I know that you aren't supposed to meet this girl but meeting her sooner will save more headaches in the long run."

He blinked before asking, "Izuku? Take five steps back."

Nemui said, "Don't listen to him, I want a picture of this!"

Izuku, knowing better, took four steps back, just in time for the explosion to miss… and to see Mei land on Grav. Nemui said, "Fuck it, close enough."
Nemui took a picture which Iida ranted about language. Grav sighed as Uraraka, Izuku, and Iida noticed the position Mei was in against Grav. Meanwhile Power Loader was complaining to Mei about her recklessness which Nemui said, "Okay Mei, you can get off Grav now."
Mei looked at Grav to say, "Hello there."
She got off of him to asked, "Who are all of you?"
Everyone introduced themselves and they went inside the shop. Grav asked bluntly, "I need a hook or something to grab far away things with, and it must be able to release easily. The tether must be strong enough to hold more than one person, and able to real in quickly. Go nuts on the other features, though."

Nemui said, "I need a suit and gas mask that are bulletproof... I also want the mask to be smiling."
Iida, Uraraka, and Izuku told her what she wanted which she smiled, "Not a problem!"

Grav piped up, "You might as well make an agency. That way, you can have these inventions improve and grow alongside whoever uses them."

Mei was busy doing designs and what not which Power Loader said, "Sorry, when she starts something... she tends to not focus with thing around her."

Grav was silent, before recommending to Power Loader, "There's a student named Hitoshi, in our class. His Quirk is Brainwashing, and it forces the victim to follow his orders. If you want Mei to take a break, or even catch some rest, I recommend going to him."

Mei quickly turned around, "I don't need sleep."
Nemui looked at her dark eyes which he asked, "When was the last time you slept?"
She said, "Wednesday!"
Nemui said, "But today is Tuesday."
She smiled, "Exactly."
Nemui poked her and she fell asleep, "Don't worry, she will wake up in eight hours."

Grav merely sighed, before leaving. Nemui then made a portal to go back to his dorm room, the other three with Mei and Powerloader.

Then a 'Chapter 5 Completed' appeared.
