To FallenSarcasm: Thanks so much~! I know, I've come across a few fics myself that made me cringe with how they interacted, I'm glad to hear I got something right! I totally agree that he probably has abandonment issues, I'd love to write something for that but I think I'll need some time to work out a plot. On spoilers, I'm only on the second book but I've accidently come across stuff about Alas Ramus, Gabriel and a bit of backstory if it involves any of them. I might still want to wait until I have some more info though...

Today's lovely Halloween-themed headcanon was suggested by CinderAshTree. Thank you, I had fun with this one~

Headcanon: Urushihara collects more negative energy than usual in the time leading up to the demons' first Halloween on Earth and passes off his wings as a costume to go trick-or-treating

Trick or Treat

"It's only for one night!"

"No."

"Come on!" Urushihara knelt in front of Maou, who was sat at the table reading, trying to ignore him, "Please...!"

Now that was unusual. Was Urushihara actually asking nicely for something? Maou turned to look at him, surprised.

"You really wanna go that badly?" Maou raised his eyebrows when Urushihara nodded, "Why?"

"When else am I gonna get free candy?!"

Of course. He should have known. Maou considered it for a moment.

"... If you get caught, it's your own fault." He turned back to his manga.

"Are you saying I can go?" Urushihara spluttered. He had expected to have to beg a little more before Maou gave in. Maybe he just wanted rid of him for a night. Over in the kitchen, Ashiya stood staring at his king in shock.

"You can go. But be careful, 'cause if you wind up getting yourself arrested, I'm not bailing you out."

But his words fell on deaf ears as Urushihara had already excitedly returned to his laptop and opened Jungle.

It was early October now and Urushihara had learned of the holiday known as Halloween. It was more of a western concept but it was becoming more and more popular in Japan recently. A time when humans would want to be scared. And he'd noticed a few odd people in the area already making preparations during his regular magic-collecting. In fact, he'd even noticed a small increase in negative energy, and there was still three weeks before the day of Halloween itself.

Maou and Ashiya had picked up on their rising magic levels as well, but they weren't quite so interested in celebrating as he was.

Over the course of the month, Urushihara was completely focused on making sure his one night out alone would go perfectly. The magic he was absorbing practically daily would easily be enough to manifest his wings to their full size, but his plain old t-shirt and jeans wouldn't suffice for a costume. Luckily, he was able to find what he needed online, as always. Black boots, pants and even a long coat similar enough to his old general's uniform, adorned with buckles and chains. Wristbands, also with buckles, to complete the look.

When the night finally came, Urushihara sat watching from the window as the youngest children were guided up and down the street by their parents. He didn't bother to look up whenever Ashiya would answer the door to any of them. He just waited until they were replaced with the older groups, including some other teenagers. His excitement grew to be too much and his wings all but burst from between his shoulder blades as he hurried to leave.

In all their years of knowing him, neither Maou nor Ashiya had ever seen him move so fast.

The night went pretty much as expected for Urushihara. He managed to collect both an immense amount of candy, and a decent amount of magic too. And even earned a few impressed stares at his wings. But at one point, he almost let his social awkwardness get the best of him when one kid walked over and reached out to touch his feathers.

"How did you make these...?"

"Hey...!" Urushihara went to retract his wings before realising his mistake and quickly stepped away instead. The boy and his friends, who were standing a few feet away, gasped in amazement.

"Did they just move?!"

"U-uh..." Urushihara stuttered slightly, "Y-yeah, pretty cool, huh?"

He could feel himself shaking but that was soon calmed by the familiar feeling of human negativity. Some of the kids did look a little unnerved by him.

Huh...

He looked back at his wings, twitching them just a little to get the children's attention, then suddenly stretched them open, fixing the group with a menacing smile. They squealed and stumbled back, giving Urushihara a much-needed rush of confidence. He brushed past them with a sly grin, drinking up their fear as he did.

I think that's enough for one night.
