Title comes from the Big Bang song Monster. The rest of the fic has pretty much nothing to do with the song other than the constant use of the word monster and the line "I'm not a monster".

"No way, Guil! Seriously!?" World End shouted. He could barely contain his excitement and had to stand up so he could jump around a bit.

"Yep. I'm serious. You better be thanking me a million times for the rest of my life for this. It's rare for anyone to even get a chance to speak with his manager." Guildenstern explained.

"A-and we getta perform with him!? On stage!? Together!? Oh man! Guil you're the best manager a band could ask for!" Wor cheered.

"Yeah, yeah. I'm great, I know. Don't stop telling me though!" Guildenstern joked.

"This is our big break Bro! We're gonna be famous and it's thanks to the coattails of your idol!" Wor stared down at his big brother, Lawless, who had been frozen still ever since Guildenstern delivered the news.

Lawless just sat there, looking forward. A half grin on his face and a thousand mile stare. It all felt like a dream to him. A wonderful, magical, beautiful dream, but a dream nonetheless. It just didn't feel real. It was like all him and Wor had worked for was finally paying off. All he dreamed of as a kid was becoming reality. Sure, it was no play, or musical, or anything to do with theater, but music and theater go hand-in-hand, right?

And not only that, but Lawless's favorite pianist would be performing with him and World End. A beauty with the hands of a God. A master with a stare as cold as ice. A real angel among mortals.

Licht Jekylland Todoroki

The eighteen-year-old child prodigy from Austria. Lawless owned every single album of his and listened to them constantly. He kept up with all of Licht's social media accounts, although he found out long ago that they aren't actually managed by Licht, but it still made him feel one step closer to getting to know Licht. He watched every single recording he could find on the internet of Licht's shows and recorded every time he's appeared on television. Unfortunately, Licht had never done interviews, nor said a word on camera. Lawless had no idea what Licht sounded like, nor what his personality may be like aside from how serious he was rumored to be. To actually come face to face with his idol was one thing, but to be one of the few people to ever perform with Licht was mind blowing. Suddenly something clicked in Lawless's mind.

"Say, haven't there only been, like, three people he's performed with? Why the heck does such a small time band like us get the opportunity?" Lawless questioned.

Guildenstern leaned back in his chair. "Aaah, that's a good question Lawless, my boy. I sweet talked his manager. I just mentioned in passing how much I like blondes with long hair and 'boom'. I immediately got a moment of his time."

"Ah! You and your old tricks Guil!" Wor pat Guildenstern on the back.

"That's great." Lawless said with a chuckle.

"You don't seem as excited as I thought you'd be Law." Guildenstern pointed out.

"Oh, I am. Really. It just… It hasn't set in yet." Lawless explained.

"Guil! Guil! When are we doin' this!?" Wor questioned.

"In two weeks. Part of the deal was that we set everything up for when he gets here. He'll only be here for five days and he leaves early the next day." Guildenstern stood and checked his phone for his schedule.

"We gotta practice best we can Law! We gotta impress Licht!" World End grabbed his elder brother's hands and jumped up and down.

"Oh crap! I got a meeting in an hour. Alright you guys can go." Guildenstern said.

"Let's go home and tell everyone!" Wor shouted as he pulled Lawless out of the recording room.

"Hey! And don't forget to come back on Thursday! You two need to practice that part we talked about!" Guildenstern shouted as the brothers left.

The two came home in time for dinner and while World End ate thirds, as usual, Lawless surprisingly didn't even finish what little food he got.

"Does the cat really have to be at dinner Ash?" The Mother asked.

"Ya." Ash replied, leaning down to pet Kuro as the cat ate from his bowl.

The Mother sighed and let her eldest brother be, knowing after numerous times that nothing would change.

"So what were you telling us earlier Wor?" All Of Love inquired.

"Oh yeah! Guil got us a gig with freakin' Licht Todoroki of all people! Law is, like, his number one fan! It's gonna be so cool! We're gonna be on stage with him and perform with him and it's totally gonna be our big break! Oh man Law! Hear me out here! What if we make a new song!?" World End proposed.

Lawless was silent for a moment and fiddled with his fork before putting it down. "Uuuh… I don't know about that. We only have two weeks and we're supposed to spend that time setting up. Plus it takes me longer than that to write lyrics. We don't really have that kinda time."

"Aaaww!" Wor whined.

"Well I'm sure you two will do great as always." Old Child encouraged.

After dinner Lawless went straight to his room, which everyone found odd but no one actually went to check on him. He sat on his bed for a moment and stared at his guitar. He wasn't sure if it just hadn't set in yet or if he skipped excitement completely and moved straight to nervousness. Maybe he was scared. After all, all his other favorite artists were dead by now. The only current person he liked was Licht.

Years and years ago he found a video from one of Licht's concerts when he was young. Ever since then he'd been completely enthralled by Licht's music. It created an emotion in Lawless that he couldn't name. One that made his heart beat faster and reminded him of what it felt like to be alive. Some of Licht's songs actually succeeded in making him cry. He couldn't explain why, it just happened. He'd read about that happening to other people who listen to his music. For that reason Licht was dubbed 'The Angel of Music'. It was rumored his mom started the angel theme.

Lawless laid back on his bed and stared at his ceiling fan. The idea of being in the same room as Licht was enough to make Lawless freak out. What if Licht didn't like him? Or thought his and World End's music wasn't good? If his own idol didn't like him… would he have the courage to keep making music?

"Maybe I shoulda stuck with acting…" Lawless muttered to himself.

On Thursday Lawless and Wor came into the studio to work on their weak points. They had to be perfect so they could impress Licht. By then Lawless had noticed all Licht's social media accounts had announced the performance. It was slowly setting in that it wasn't a dream after all. Guildenstern got working on booking the venue. He didn't cut any expense this time and got the biggest place in town. Although, considering the town itself was kind of small the place wasn't as impressive as one you'd find in a big name city. Saturday Guildenstern received a call from Licht's manager, Rosen Crantz. He was simply calling to confirm some small details. Sunday All Of Love and The Mother made a cake for the duo to celebrate. Wor ate most of it of course. Monday was spent practicing again and the two came home more tired than usual that day. It didn't help that Guildenstern needed them to come in everyday from then until the performance. Tuesday to Sunday was filled with the brothers running around the venue setting everything up, making errand runs for Guil, and advertising. It was already pretty late by the time they got home on Sunday night.

"Ugh! Since when did the talent hafta do all the hard work? Aren't we supposed to just play our music and get hoards of fans after us?" Wor whined as they entered the main room of the house.

On the couch was Sleepy Ash with Old Child in his lap and Kuro sleeping against his leg.

"Ash, remember when we stayed inside all day and were feared as monsters by the townspeople? I miss those days when we were decent normal immortals." Old Child complained.

"Hey! We are not monsters! We're just as normal as the rest of the town and thanks to all the fans we have in town, most people don't fear the Ash family anymore!" Lawless corrected as he sat down at the dining table.

"Aren't you guys idols or something anyway? Of course you're gonna have fans. That comes with the territory." Ash muttered.

"Idols!? Bro, we're not idols. We're a band! We play instruments. Idols just dance around and sing and look hot." Lawless said.

"Are you saying you don't look hot?" Ash questioned, eliciting a laugh from Old Child and World End.

"You know what I meant Ash!" Lawless shouted, getting fed up and looking away towards the kitchen.

"Honestly, not really." Sleepy Ash mumbled under his breath, which made Old Child chuckle again.

"Here man." Wor said as he slid a glass of milk in front of his elder brother.

"Thanks." Lawless picked it up and took a sip.

"So are we invited to the show?" Old Child asked.

"Oh crap, we totally didn't think about!" Wor shouted.

Lawless thought about it for a moment. If Licht met their siblings, he might think they were just as weird as all the others. Lawless wasn't really wasn't sure he wanted that.

"Yeaaahh… I don't know…" Lawless trailed off.

"Well count me out. I'd rather stay home and sleep." The eldest said.

"Ah, if Ash isn't going then I don't want to either." Old Child chimed in.

"You heard the five-year-old. We're not going." Ash announced. "And you should probably get to bed soon. It's getting late."

Ash stood, still holding Old Child and went to leave the room. Kuro woke up and jumped off the couch to follow Ash.

"Noooo! I do not want to go sleep! You can't make me Ash!" Old Child whined as he flailed his arms and legs.

"Nighty-night!" Wor said with a wave of his hand.

"You fool! Save me! I command you! I'm older than you! Assist me! I am not ready for bed time!" The second eldest practically screamed as Ash carried him up the stairs.

"I wish we had a bedtime." Wor said and sat down at the table.

"Dude. You can just go to sleep. No one needs to tell you to do that." Lawless took the last sip of his drink.

"Oh. Yeah. I should do that. You headin' up?" Wor asked as he stood.

"Yeah, I'll head to bed in a minute." Lawless said as Wor exited the room and headed up the stairs.

Lawless sighed and stared at his empty glass. Tomorrow. Tomorrow they'd head back to the venue to practice and at some point Licht would show up. He was going to meet the Licht Jekylland Todoroki. With no idea of how it would go, Lawless felt too nervous to sleep. He trudged upstairs and past his own room to stop in front of Tsubaki's door. He held an ear up to the door, but didn't hear anything. He assumed Tsubaki was either out with that gang of his, or already asleep. He walked back to his own room.

Lawless changed into his pajamas and sat on his bed. He didn't really want to sleep yet, what with all the worrying he was doing. He walked over to his guitar and picked up. Lawless plucked a few of the strings without any real reason. The sound made him want to play more and he played the first few notes of the first song that popped in his head. Of course it just had to be one of Licht's songs. Lawless kept playing the song and started tapping his foot along with it. The thought crossed his mind that Licht might be impressed if he heard a song of his played on the guitar. Maybe that's what Lawless should do. He already knew how to play every song of the pianist's anyway.

His concentration broke when his door slammed open and Doubt Doubt stood in the doorway.

"Knock it off and go to sleep or I break it." He grumbled.

"Eep! K-kay!" Lawless said, gripping onto his guitar like his life depended on it.

Doubt walked away and shut the door behind him. Lawless sighed and placed his guitar on its stand. He walked back to his bed and laid down for a few hours until he finally fell asleep.

In the morning, Lawless and World End headed out to the venue after eating breakfast and impatiently waited at a table backstage for their manager to arrive. Lawless had his head on the table and Wor was beating the edge with his drum sticks.

"How come we gotta get here so early and Guil can roll in whenever he wants?" Law muttered into the table.

"You good man? You seem tired." Wor inquired, poking his brother's head with one of the drum sticks.

"I'm fine, I just didn't sleep long last night." Lawless mumbled.

"Heh. You're starting to sound like Ash." Wor stated.

Lawless threw his head up. "I do not sound like Nyash! ...Besides, he can't help his sleeping issues. I think I'm just nervous." Lawless put his head back down and groaned.

"Hey, what are you two doing? You should be practicing. Chop chop boys." Guildenstern walked in and clapped his hands to get the brothers' attention.

"Finallyyyyy!" They both whined and stood up from the table.

The two brothers headed to the stage and Lawless grabbed his guitar, plugging into the amp.

"Remember, Licht is coming in about an hour. Your careers depend on his first impression of you, so you better impress him!" Guil announced, the emptiness of the auditorium making his voice echo.

The duo casually played a few random parts of several of their songs before deciding to play the entirety of their newest one that they'd been having trouble on. Half way in Lawless messed up and they stated over. At the same part Lawless fumbled a few notes and stopped playing.

"Still havin' trouble with that part Law?" Wor asked.

"No." Lawless lied.

They tried again one more time and finally Lawless made it passed the difficult part. They kept going with the song and made it close to the end when Lawless stumbled on one simple note and dropped his arms.

"Come on Lawless, really?" Guildenstern complained.

Wor stared at his brother with a worried expression.

Lawless glanced down at his guitar. He couldn't concentrate on the song, but wasn't sure why. Maybe it was stress. Maybe anxiety. Either way, he put his hands back on his guitar and just started playing. Not one of his and Wor's songs though, but one of Licht's. His favorite actually. When World End figured out what song Lawless was playing he smiled and hummed along while Guildenstern sighed and slumped in his chair.

"Do you hear that?" Licht asked.

"Hmm? Oh my, I do actually. Wonder what it is." Crantz inquired.

"It's my song." Licht whispered as he pushed open the door to the auditorium and walked down the aisle, Crantz following after him.

He stared up at Lawless, who had his eyes shut as he played. The second he saw the blond's face he froze. Licht scowled and clenched his fists in his hoodie pocket. To think that a song created by an angel was being played by some… some monster. He didn't need to know who this man was, Licht could already sense that Lawless wasn't normal the second he entered the room. Whatever he was, Lawless was a monster and a monster didn't deserve to listen to the music of an angel, let alone play it.

Lawless finished the song and opened his eyes. He looked down to see Licht staring up at him with his signature glare on his face. Lawless's eyes widened behind his glasses. There he was. Licht Jekylland Todoroki. Standing right in front of Lawless. He was better looking in real life. His piercing icy blue eyes stood out so much, even despite the distance between them. The wings on his backpack really made him look like the angel he was always referred to. To Lawless, even without a halo he was the most beautiful angel the blond had ever seen.

When Guildenstern realize Licht and his manager were standing there, he sprung right up and went to greet them. "O-oh excuse me I didn't hear you come in. I'm Guildenstern, Lawless and World End's manager. It's wonderful to meet you."

"Ah, yes. It's a pleasure to meet you too. Rosen Crantz, we spoke over the phone a few times." Crantz and Guil smiled and shook hands.

Wor jumped up and ran over to Lawless, who kept staring back at Licht. "Dude, there he is. Licht. Jekylland. Todoroki!"

Without breaking eye contact, Lawless placed his guitar down and hopped off the stage. He walked up to Licht and noticed the angel was just a tiny bit shorter than him despite physically being the same age. Up close Licht's features were more noticeable and Lawless couldn't help but blush slightly. He opened his mouth to say something, but couldn't bring himself to actually say anything. Licht, on the other hand, continued to glare. It even looked like to Lawless that the angel was starting to look angrier and angrier.

Just as Lawless worked up enough courage to finally speak, Licht beat him to it. "There is no way in hell I'm sharing a stage with a monster."

And it was then that Lawless knew.

Licht Jekylland Todoroki… was an asshole.
