(When Alintor talks in your mind, it'll be in italics)

Hayato was on top of the world right now. He killed the guy he hates the most and he's going to get a power boost later today, a total win-win for him! Ms. Ross and Dewitt are concerned about Y/N's absence, so he simply comforts them. As we speak, his Fallen allies are preparing to take the Sacred Gear out of Y/N's soul while Hayato was at school. Currently, Hayato is walking to where he killed Y/N.

Hayato: Now I see why murders return to the scene of the crime. Too bad no one knows about it.

Fallen: Hayato!!!

Hayato turns around to see another Fallen ally he's friends with. This Fallen is overweight with glasses with a dingy white shirt, blue jeans, and brown shoes. This is Tanaka, another Fallen who is notorious for his lust like Hayato.

Tanaka: We have a problem!!

Hayato: What's wrong?

Tanaka: Y/N isn't dead!

Hayato: WHAT?!?

Now this is a massive surprise for Hayato. He personally made sure Y/N died, or at least passed out to make the extraction easier. The Supernatural in the area always felt a faint yet dominant, bordering on Dragonic, aura from Y/N. Hayato grits his teeth in rage. Y/N being alive jeopardizes not only his plan to gain power, but he'll also ruin his plan to break Ms. Ross and Ms. Dewitt.

Hayato: Send every Fallen we have to find him! His Sacred Gear is too dangerous to be unaligned if Kokabiel wants us to get it. The Devils already have something on their side, the guy Raynare failed to kill. Apparently, he's now part of the Gremory Peerage.

Tanaka: Got it.

Tanaka grows a pair of black bird wings before flying off. Hayato calms down and walks to school, trying to calm himself. If Y/N is alive, Hayato will kill him again, Peerage aligned or otherwise. At least, that's what he tells himself. Eventually, Hayato makes it to the school and into Ms. Ross's class. Hayato sits down and pays attention to the slightly sad Ms. Ross. Since Y/N hasn't been to school from Monday to Thursday, she's been a bit worried because he never wants to miss her class. She misses his unique art style and his views on everything from major things like current issues to small things like food. Ms. Dewitt is concerned as well as she misses his talent, enthusiasm, and willingness to learn. Secretly, however, both women just miss the metalhead male as they've developed a taboo crush on him. As Hayato daydreams about Ms. Ross and Dewitt being his personal sluts, the door opens, making everyone look at the late student. Much to Hayato's shock and anger, it's the very person he wanted to kill.

Ms. Ross: Y/N?

Y/N: Sorry I'm late Ms. Ross, my grandad wouldn't let me come to school on the count of this.

Y/N points to his eyes. Since she's a considerable distance away, she walks closer to get a better look at what he's talking about. Looking at his eyes, she's actually captivated by their unique look as they fit his intense and rebellious attitude.

Y/N: Apparently it runs in my family. When we hit some weird biological threshold, our eyes change colors. Mine didn't though, so I got slit pupils.

Ms. Ross smiles as nothing is wrong with Y/N, something Ms. Dewitt will be happy to know as well. She motions for him to take a seat, which he happily does in his usual spot in the back of the classroom. Due to the class doing a painting-based assignment, everyone is split into pairs. Y/N however chooses to be by himself despite the class containing 17 students. Ms. Ross gave him the option of joining another pair, but he usually declines to finish the assignment quicker. She's accepted this as his unique art style doesn't go well with the other students.

Ms. Ross: Ok class, today we'll be painting.

Tanaka raises his hand. Despite Hayato sending him on a search, he has to attend school to blend in the human world. So, he attends Kuoh Academy with Hayato.

Tanaka: What are we supposed to paint?

Ms. Ross smiles sweetly. Because of this, both Tanaka and Hayato are having perverted daydreams about the petite teacher. Two members of the Pervert Trio, Issei and Matsuda, are also in the same class and having perverted daydreams about her as well. Ms. Ross is well aware of this but pays no mind to it as she only cares for how one man sees her.

Ms. Ross: If I tell you what to paint, then it wouldn't be actual art. In layman's terms, paint what makes you, you.

Slightly enthused, the pairs begin painting. This assignment has been going on for a full week, so most of them are adding the finishing touches to previous paintings or still adding large portions. Y/N smirks and grabs some red, grayish-blue, and black paint to color his sketch. After about 17 minutes, Ms. Ross comes over to look at his painting. 

Ms. Ross: Even when painting, you keep the same dark themes. 

Y/N: They look nice. That's actually my 4th painting.

Ms. Ross: May I see the rest?

Y/N: Sure, I painted them on smaller canvases to make it easier to travel with them.

Ms. Ross: There are times when I would love to delve deep into your mind and see your imagination.

Alintor: If she does, I hope she's prepared to be mentally scarred and Caught in a Mosh.

Y/N: Shut up you overgrown lizard.

The dragon and his host chuckle inwardly. Over the 5 days they've been in contact, Y/N and Alintor have become close friends, bro status really. Y/N decides to listen to music as he's done with his assignment and waits for the day to go by.

Alintor: Aw hell yeah! Turn that shit all the way up!

Timeskip brought to you by

Ms. Ross and Dewitt can be seen walking home together. Both of them share an apartment thanks to the program they're part of and decided to have some fun after school today. It's getting close to dusk, but there's still enough light out for them to see. The women enjoy each other's company and love to share stories from their classes.

Barbra (Ms. Ross's first name): Aren't you glad Y/N's back in school Melody (Ms. Dewitt's first name)?

Melody: Definitely. His eyes do look pretty to me. 

Barbra: They fit his wild style perfectly. It makes me wonder how the rest of his family's eyes look.

Suddenly, the sky's colors begin to distort and the women stop in confusion. A creepy laugh reverberates through the air, scaring the women. Suddenly, 10 humans with black bird wings descend from the sky, and among them are Hayato and Tanaka.

Tanaka: We finally have you both alone. 

Hayato: Who's your slut gonna be Tanaka?

Tanaka: Ms. Dewitt, I love me some chocolate.

???: Well chocolate doesn't love you, dumbass.

Tanaka: Who said that?!

???: Me.

Everyone's attention is turned to the shadows, where a figure can be seen with a weapon over his shoulder. You can tell it's a male thanks to his masculine frame, an extremely tall one at that. His attire consists of an open black denim jacket that reveals his muscular torso, black jeans decorated with skulls, and black boots.

Tanaka: Come out of the shadows so I can see the ugly mug I get to put a spear in!

???: Yeah, my mug looks a hell of a lot better than yours pal.

The figure walks out of the shadows to reveal a smirking Y/N, who has his axe-guitar over his shoulder. Tanaka, Hayato, and the teacher's eyes go wide for different reasons. The boys are angry at his mocking smirk and the fact they feel a stronger supernatural aura while the women have blushing faces at his muscular body.

Hatayo: You! I knew I should've dragged your half dead ass to the base!

Y/N: But you didn't~! Loser. Bozo. 

Hayato charges at Y/N with a red light spear, but the taller male counters with his axe. His smirk never leaves as he holds off Hayato.

Y/N: Damn, I didn't think you were weaker than a modern rapper's tolerance to drugs!

Hayato: Shut up!

Hayato goes for a thrust, only for Y/N to use his face as a stepping stone to perform a backflip. When he lands, he holds his guitar in the air with his feet shoulder width apart.

Y/N: Stygian Tristitia, guitar of the Hell Wolf Wyvern. Let my hellish melodies violently shake the earth!

Dark clouded storms appear as red lightning strikes through the barrier, hitting Y/N's guitar. Red sparks dance off it as the guitar molds into something more bestial.

Tanaka: W-what the hell is this power!?

Y/N: Power metal bitch!

Y/N slams Stygian Tristitia into Tanaka's stomach, causing him to vomit blood as he gets sent into the wall. Hayato throws a light spear at Y/N, but he dodges it and uses his red electricity to shock the perverted fallen. He laughs at Hayato's pained scream before playing a note on Stygian Tristitia, sending a shockwave of red electricity around him. It doesn't harm Melody or Barbra, but the same can't be said for the rest of the Fallen. The electricity fries many of the fallen to death, but Tanaka and Hayato are only injured.

Y/N: Damn, didn't think I had that much control over Stygian Tristitia's electricity.

Alintor: You're a fast learner, but you still have a ways to go partner.

Hayato: Why....

Y/N: Why what?

Hayato: WHY DOES ALL THE GOOD SHIT HAPPEN TO A BASTARD LIKE YOU?! FIRST YOU BECOME MR. POPULAR AT KUOH DESPITE BEING A WEIRD ASS INTROVERT, THEN TWO OF THE HOTTEST TEACHERS HAVE A CRUSH ON YOU FOR BEING A SIGMA MALE, AND NOW YOU COME BACK FROM BEING DEAD WITH A POWERFUL ASS SACRED GEAR! IT'S NOT FUCKING FAIR! I SHOULD BE THE ONE GETTING ALL OF THE POWER AND BITCHES, ME! A FALLEN ANGEL! NOT SOME WEAK, PATHETIC, INSIGNIFICANT HUMAN LIKE YOU!

Y/N: You really wanna know why?

Hayato: YES!

Y/N: Fuck you that's why.

Hayato: I'LL FUCKING KILL YOU! AND THEN I'M GONNA FUCK THOSE TWO FOREIGN BITCHES UNTIL THEY'RE BEGGING FOR MY DICK!

Hayato charges at Y/N with a light spear made from his remaining magical power. Y/N however dodges and slams Stygian Tristitia into Hayato's back, hard. Hayato yells in pain as he falls, barely being able to stand up from all of the pain combined with exhaustion. Hayato grits his teeth and shoots a needle of red light at Y/N, who simply moves his head to the side.

Tanaka: I'll get you!

With a green light axe in hand, Tanaka goes for a surprise attack on Y/N. Y/N manages to counter and push Tanaka away before playing something on his guitar. He strikes the last note with extreme ferocity as if he's excited for what's to come.

Y/N: WAKE UP YOU FACELESS FUCKERS, IT'S FEEDING TIME!

As soon as he says that, human hands come out of the ground and grab any Fallen who don't escape in time, which is all but about 2. Tanaka and Hayato aren't so lucky as several of the faceless undead pin them to the ground. Hayato seethes at a smirking Y/N, unable to get up from the surprisingly strong undead.

Hayato: Let me go you bastard! What even are these things?!

Y/N: My army ass hat, I call these guys Moshers. When I first met them, they just crashed into each other like a fucking mosh pit, you'll like it.

Hayato doesn't really get it, but Tanaka does.

Tanaka: NO!

Y/N: OH YEAH!

Playing another solo, Y/N slams his guitar into Tanaka's chest, killing him instantly. As the Moshers let him go, Tanaka's flesh slowly melts off until he's nothing but a skeleton with Fallen wings. The metalhead stops to admire his work.

Y/N: Huh, that's pretty cool actually. Do you keep those green light weapons?

The skeleton makes a green lightspear, answering its master's question. Hayato looks in horror at what his enemy did to his best friend and subordinate. That horror increases as Y/N walks towards him, his guitar dragging against the ground and his boots clacking with every step.

Hatayo: W-wait, don't kill me! I can give you anything: money, power, women, even information!

Y/N stops and looks at him with intrigue. Though Alintor told him about the supernatural, his spectrum of information is rather broad. It's mostly general things many of the supernatural know with the added benefit of knowing the big people up and downstairs died. Having Hayato, a Fallen willing to give information for his own life, with him is definitely gonna be helpful. He twirls Stygian Tristitia and rests it on his shoulder.

Y/N: Alright, I'll let you live...

Hayato smiles and thanks Y/N several times, only to feel the Mosher's hands pull him to the ground.

Hayato: W-wait, you said you wouldn't kill me!

Y/N: Yeah, but you ain't leaving either. Nine times out of ten, you'll go bitch to your little boss about my Sacred Gear and shit, so you'll be spending time with my Moshers.

Hayato screams curses at Y/N, who just shrugs as he's pulled into the home of the Moshers. Satisfied with everything, including turning the other Fallen into Moshers with Fallen Angel powers, he twirls Stygian Tristitia and turns it back into his regular guitar. Before he knew it, he was tackled in a hug by a sniffling Barbra.

Y/N: You ok Ms. Ross?

Barbra: N-not really...that entire experience....knowing two of my students were going to go that far...all of this...

Y/N: I understand. But hey, one's dead and the other one's basically running for his life right now.

Melody: That doesn't help, but it's comforting coming from you.

Y/N: Want me to walk you both home? I plan on bullshitting around anyways so I got time.

They smile a little at Y/N's laid back attitude. Though, they're a little concerned that he isn't the least bit affected by killing two of his classmates. The tall male puts Barbra on his back, making Melody pout a little before they walk.

Barbra: So those....things...they're Angels?

Y/N: Fallen Angels to be more precise. You know, the guys who got kicked out by the big man upstairs for not conforming to what Christians see as virtuous.

Melody: So God is real....?

Alintor: Before you say ANYTHING stupid, you can't tell them God kicked the bucket. It'll fuck with the balance the three factions have and the last thing I want is a stupid war.....yeah that's the last thing I want. Had to think about it for a second.

Y/N: Yup. God, Zeus, Saturn, Odin, Osiris, Amaterasu Ōmikami, Huitzilopochtli, all of them are real. That's the thing Christians and the other extreme Abrahamics lied about. Magic and monsters are real too.

Barbra: Really?

Y/N: You sound excited.

Barbra: The prospect of meeting real supernatural creatures and not just reading about them sounds fun. I hope I can meet one sometime.

Y/N: I ain't got a doubt in my mind you will. Plus, I'll try to help you with it since I am technically part of the supernatural.

Melody: Are you a demon?

Barbra: A dragon?

Y/N: I wish, but no. I'm a human with something called a Sacred Gear. It's these rare objects created by the Christian God for humans, or human hybrids if you got some bullshit luck. Some have the souls of strong creatures, others don't but can still give them an edge in the supernatural world. Some famous people in history had Sacred Gears and used them to their advantage.

Melody: So what is your Sacred Gear called?

Y/N: Mine is called Cataclysmic Rhythm and it's made from the soul of Alintor, he who reigned in the blood of a thousand beasts. Basically, it allows me to turn my guitar into different weapons from the monsters Alintor killed when he was alive. Each one has a different power, like Stygian Tristitia's red electricity.

Barbra: What about those zombies?

Y/N: Oh, my Moshers. Well, those boneheads are pretty interesting with how they were born. See, an army of peasants was used as a king's last ditch effort to kill Alintor during the Great War. He offered them the choice of serving him or dying a miserable death. As you can see, they chose the former and were blasted with concentrated energy from Alintor, making them stronger but unhinged undead metalheads as a result. I can summon them, but not too many because they tend to go and cause chaos somewhere else. Like I did with Tanaka, I can turn people into Moshers if I'm strong enough to handle the backlash, but I didn't expect they'd keep some powers from when they were alive. Imagine summoning a black winged skeleton that throws spears of green light!

The women giggle at Y/N's enthusiasm. Eventually, they make it to the teacher's shared apartment and he lowers Barbra off of his back.

Melody: We appreciate you helping us Y/N.

Y/N: Don't sweat it. You two are my favorite teachers and I don't want anything bad to happen.

Melody: Well...would you like to come in?

Y/N: Sure.

Melody unlocks the door and Y/N walks in. As expected from teachers who are deeply passionate about their subjects, there are numerous decorations about art and music. Courtesy of Barbra, there's lots of paintings that she made of different things, from animals to abstract pieces. There's even a statue or two. From Melody however, there's posters of famous black musicians such as Robert Johnson, Louis Armstrong, Jimi Hendrix, Ray Charles, Stevie Wonder, Muddy Waters, Prince, Michael Jackson, and even obscure people like Big Mama Thorton.

Y/N: Huh, looks like you said fuck you to the rappers of the States.

Melody: What did you say in music class? "If metal gives you a headache, then rap gives you cancer.", I think that's what it was.

Y/N: Oh wow, using my own words against me. And you do have some good rappers, but most of them are old school. 

Melody giggled at Y/N.

Barbra: I can't really add any input. I say I listen to all kinds of music but the stuff Y/N listens to is too scary for me.

Y/N: Oh that's how everyone is. Metal is like cooking, there's different types for everyone to enjoy. I just so happen to enjoy almost all of them.

Melody: Almost all? What do you not like?

Y/N: Nu metal, but not because it's mainstream. I don't really care for it because most nu metal bands don't know about metal but get lumped together with other metal genres. Like how most of them don't do guitar solos, the cornerstone of the metal genre. I'll listen to it if the song is good, but that's about it. Like I like some Disturbed songs because they give the same feeling as Thrash metal, and rarely Power Metal. 

Suddenly, there's a loud but low groaning sound. Melody and Y/N look confused, with the former hiding behind the latter out of worry. They look to see if Barbra's scared as well, only to see her holding her stomach with a blush on her face.

Barbra: Sorry...I haven't really eaten anything today. Can we order something?

The two chuckle at the artist as Melody orders take out. Throughout the night, they forgot about their own roles as teachers and student and had fun like a normal group of friends. Playing board games, watching movies, telling stories, and even doing activities Barbra and Melody enjoy such as painting and listening to music by older artists. All and all, the night was fun despite what happened today.
