DEVILS WILL CRY

The Problem

After everything that had happened, y/n returned to a somewhat normal life. He took classes, had lunch, went home, everything was normal. But not entirely. After school, he had to help Rias with his devil duties, not that he minded, most of his pacts were simple and fun, like Alex.

But with his arm, he got asked alot of questions, both at school and work. However, that was about to change

It all started when Y/n was in the toilet. Someone had made a 'mess' and left it like a cunt. And when Y/n tried to leave, he wasn't that lucky

Left on the floor in a puddle of piss, he thought it couldn't get any worse

It can

It definitely can

His cast that was on his arm had broken, and his arm was now exposed. Which wouldn't have been as bad, if it hadn't mutated since the acid attack

Thinking of no other alternatives, Y/n called Kiba

"Y/n? What's up?"
"Toilets, third floor, come pick me up"

Y/n then hang up, leaving Kiba with no info

You'd do the same thing if you were covered in piss

After a few minutes, Kiba arrived to save the day.

"Y/n? You said you needed help?"
"Yeah, I did"
"Why do you smell of piss?"
"Shut up"

Y/n pointed a finger at Kiba to emphasise his point

"Gimme your jumper"
"Why?"
"I need it"
"Okay, but you're going to have to tell me what's happening"
"At the clubhouse, Rias need to explain something"

Kiba took off his jumper and gave it to Y/n, who then used it to cover his arm

After a short walk, a shower, a change of clothes, Y/n was ready to explain what had happened

"Thanks for the spare clothes Kiba"
"No problem, so what happened anyway?"
"Well I was taking a piss, then I tripped, fell in piss, broke my cast, and then this happened"

Y/n showed his new arm to the rest of the group, all of them were shocked, but mostly Rias

"It looks like a dragon arm, but it feels... Off..."
"Dragon? Big lizard? Fire breathing? I didn't think they'd have arms"
"They don't, but some sacred gears allow their users to trade their normal arm for one with dragon properties, but that's not a dragon's"
"How can you tell?"
"Because it reeks of extremely powerful demonic energy. You should go home and get another cast, you won't want people seeing it"
"True. See you guys later!"

Y/n quickly left, excited to get a day off. Rias, however, quickly started looking through the bookshelves

"Rias? What are you looking for?"
"A few years ago a group called the Order of the Sword was taken down by two people, one was a Demon named Dante, the other was a former member called Nero, I have a book about it somewhere... Ah!"

She pulled out a book with a leather cover, and opened it to a page describing the two

"While not possessing many demonic traits, Nero poseesed an arm that had incredible demonic power. My theory is that he is at least partially demon, much like Dante, who I discovered to be a cambion. A half human, half demon being who possesses immense power, especially when using devil arms, weapons designed to kill demons" Rias quoted

"So if Y/n's like nero, then he's a Demon?"
"That's my theory"
"Aren't we demons?" issei asked
"No. While we share similar traits, demons are much more primal, and therefore more powerful. However, some, like Sparda, rebel against hell for the sake of humanity"
"So they're stronger?"
"Yes"
"And Y/n's one of them? Why does he get to be so strong?!"
"Because he thinks about more than just boobs" Koneko said flatly (Pun intended)
