Chapter 1: Song of the Siren

WARNING: Noir, here! Gonna get into OC heavy territory- but this story is sort of in the background taking place in the same made-up region of Japan during the events of the manga/anime, so I'll be referencing those events from time to time… and might include some of the canon characters in these chapters. No spoilers for now; but keep that in mind. Hey did you know that the made-up Japanese city name for MHA "Musatafu" is actually a pun on the planet Mustafar from Star Wars?! Yeah! Awesome, right?! Was inspired by a friend of mine to write an OC-focused fic from MHA, since they did the same. This is sort of an original story more than a fanfiction so if you don't like OC-heavy fics with lotsa words then I would advise you leave. Thank you and happy reading. :)

~9o9~

The streets of Musutafu Japan laid bare in the crescent moonlit sky… but of course that was only because those who live a life of sin wait for all the good people to head back to their lovely safe homes and crawl out of their hiding holes to seize their opportunity to make a profit.

A Siren woman with long flowing blue hair with scale-covered legs crept forward, leading a group of four lead behind her as she weaved through the glowing nightlights of the sleeping city. While the city indeed was asleep, that didn't mean all lights were off on the streets- there were assigned all-nighter heroes on alert out for criminals like the Siren's pack.

But of course, they don't care, for profit was the only thing on their minds as the Siren promised them so. As she weaved through the streetlights, the short green-haired girl in the purple kimono among the group winced as her Shamisen guitar handle banged against one of the trash bins as the Siren made a hard left, leading the gang towards the bank. The rest of the group gave her snarls and visible warnings and the girl rolled her eyes, as if she cared. If all of them were caught all their efforts wouldn't matter in the long run.

The Siren then raised a hand, stopping the pack against the corner of the building and ran ahead, scouting both sides of the sidewalk if anyone else were present. Then she raised her hand again and pointed to one of the group members with a dog's head. Quickly he jumped on all fours and ran up to her, sniffing the air and confirmed her theory- there were no one around. Then the Siren lifted a hand and motioned them forward, and the rest followed.

A Siren, a Dog, a young girl with a Shamisen, a chameleon-like humanoid with red skin, and a ghost girl with the ability to go through anything stood in front of the city bank upon its sidewalk, its lights out and its windows barred tight. Immediately the Siren turned to the Ghost Girl and she floated forward and through the entrance of the building. Immediately the chameleon followed, disappearing within view thanks to his quirk and began picking at the lock using his long claws should the ghost girl fail to find the key to the door while the rest hid behind the dark side of the building.

However immediately as soon as the remaining three criminals hid, footsteps were immediately heard. Quickly the chameleon froze, able to shrink his claws back into his nails as he stood in front of the bank entrance, eerily still as using his pinkie he tapped the door lightly three times, signaling the ghost girl inside that someone was outside.

A Pro Hero- Best Jeanist, was patrolling the streets, adjusting and opening the belt suspending his denim mouth-warmer to create an opening as he breathed loudly, creating a small puff of smoke from his mouth then quickly shutting it immediately.

"How unfortunate winter offers so limited variety of clothing. Then again, their selection isn't too bad." Jeanist adjusted his belt again and stared closely at the entrance to the city bank, leering upon any trace of criminal activity.

The chameleon grew tense, clenching his teeth as Jeanist stared upon the entrance for a long time until he found nothing, not a single trace, then shifted his attention elsewhere and continued walking forward.

"A shame, really, for winter's often a time for vacation and spending time with loved ones. A fixed, tight-belted agenda, often a requirement to those who don't choose to rest in this sleepy weather." Jeanist spoke again and turned to the door, which nowhe noticed something out of the ordinary- a reptilian claw.

"Especially for people like you." Jeanist swiped an arm forward and the fibers upon his clothing immediately jutted outwards and aimed straight for the camouflaged reptile, restraining his arms to his chest immediately. The chameleon's red skin immediately became visible to the Pro Hero's eyes as he dragged him forward to his view.

"So distasteful in attire. Then again all criminals like you are always dressed in rags!" Jeanist lurched him forward and flicked his arm back, sending the chameleon straight against the pavement, calculatingly avoided throwing him against buildings for property's sake. The criminal snarled and immediately disappeared again as the threads keeping him restrained were sliced as Jeanist held his threads at the ready, waiting for the animal to pounce.

"Shameful, unpleasant, offensive. These are the traits that make up a badly dressed criminal." Jeanist shifted his eyes back as he noticed the Reptile move behind him before he could strike and brought his hand behind him, managing to snag the Reptile by the waist and dragged him forward towards the Pro Hero's face, leering at him. "Dreadfully brutish peoplelike you must be reformed."

The dog criminal howled, causing Best Jeanist's attention to shift elsewhere towards the dog as he charged towards the man and tackled him to the ground. As Jeanist attempted to weave threads from his denim clothing, the dog snarled at him and drenched his hands with saliva, causing his grip upon his threads to loosen and slip. Jeanist wrinkled his nose as the Chameleon immediately was set free and charged back towards the door, which the Ghost Girl had thankfully managed to open in time. The dog restrained the Pro Hero and howled, notifying Siren and the girl of the news and the Siren, now smirking with victory as she quickly turned to the girl and motioned her to wait outside as she snuck in the bank entrance.

"Wha- there's a Pro Hero out there!" The girl snarled; pointing straight at the restrained hero, whose threads had slowly began weaving around the dog criminal, wrapping around his limbs very slowly so that he wouldn't notice.

"And you'll be the one to keep him out of our way with Osamu's help. See? He's doing his job, so you should do yours." The Siren pointed to the dog restraining the hero then quickly rushed inside, leaving the girl behind.

"Psh, yeah, and I'll watch you all gallantly fail at doing everything for me as a Pro Hero kicks all your guys' asses." Aiko Hikari rolled her eyes, crossing her arms as she strummed the two strings upon her Shamisen. Sighing, she leaned against the bank's walls and watched as Osamu restraining the Pro Hero suddenly was thrown off as Jeanist lifted him with his threads, wrapping his limbs tightly around his mouth and clamping his lips shut.

"Abusing my threads with drool so I wouldn't be able to weave; clever, but disgusting. You should be taught a thing or two about personal hygiene." Jeanist flicked his left hand upon the threads suspending Osamu, causing another set of strings to wrap around his body into a tightly-knit cocoon as with his other hand he checked his phone, contacting any Pro Hero nearby to assist. "Five of them, outside of Musatfu Bank. I've got one, the others won't be too hard."

Then he stepped forward, stepping in towards the bank but was met with resistance as the Chameleon suddenly jumped straight at him, grabbing his face and attempting to rip his head out of his denim neck-warmer.

"Oh really now, I like my neck-warmer." Threads immediately restrained the chameleon as the Pro Hero stared straight into its multi-colored eyes, his expression calm and emotionless but his glare all-the-more threatening. "I would loathe they be ripped by some foreign reptile."

However the chameleon's claws were sharp and he managed to slash his way through and immediately attempted to free Osamu, jumping nimbly in his direction but was swatted away immediately.

"Friends and fellow criminals aren't the same thing! You should think wiser before planning to commit a life of sin! Because if you don't-" Jeanist snagged the reptile by the collar with his own hand, squeezing the fabric tightly. "You'll be left behind."


"Hurry! Ichigo, the passcode!" The Siren called to the floating girl as she hovered over towards the electrical passcode-lock for the safe after digging her hand through the drawers of the bank owner's private office and dialed the number according to the slip of paper she found. The lock dinged in recognition and the safe door burst open, allowing the Siren and the girl to step inside.

"That rewards you another strawberry, Ghost Girl." The Siren reached into her pocket and flung a strawberry behind her head as Ichigo caught it, stuffing it hungrily down her throat. Quickly the Siren then reached over to her hips to extend out long scaled flaps from her legs and stuffed the money within them as much as she could fit, then enclosing them deep within the folds of the scales. Quickly she turned to Ichigo and nodded, then sprinted forward outside and greeting Aiko at the entrance.

"We got enough! Tell the others to fall back!" The Siren ordered, dashing forward with Ichigo floating along.

"Why don't you do it? You're the leader." Aiko complained, growing tense as she watched the Chameleon be held by the collar by the Pro Hero.

"Oh come on, just do this one last thing for me and I promise I won't burden you with commands from me anymore." The Siren grinned in an attempt at sympathy, but she was lying through her teeth as Aiko noticed.

"Damn adults." Aiko snarled and brought both of her hands to her mouth to amplify her voice. "HEY ANIMALS! WE GOT WHAT WE CAME HERE FOR! LET'S GET OUTTA HERE! ORDERS FROM MIZU!"

Immediately the Chameleon turned to Osamu and managed to rip open his bonds, allowing him to escape as Chameleon rode upon his back.

"Do you honestly think you can outrun a Pro Hero?" Jeanist flicked his fingers again and the threads immediately flew towards them in blinding speed.

Quickly Aiko sprinted forward briskly and brought her hands outwards, creating a large purple portal that sucked the threads in and forcefully closed it, severing them.

"Oh?" Jeanist adjusted the belt upon his neck-warmer, tightening it.

Aiko panted heavily, out of breath as it took all of her strength to sprint to where she was at and realized she was dangerously vulnerable at that very moment.

"You're a new face to the criminal scene. I don't recall we've met, little one." Jeanist then sent another array of threads forward and Aiko used her quirk again to sever them.

"Ah, so a quirk of misplacement, then- to sever my threads by transporting them elsewhere, such a useful mischievous quirk for a criminal like you." Jeanist taunted as Aiko continued to throw portals upon the threads, buying her partners time as well as attempting to stand toe-to-toe with a Pro Hero, the 3rd-ranked one at that.

"You think your legacy and your abilities scare me?" Aiko sneered, teleporting herself up upon Jeanist's back and tackling him to the ground, restraining his arms. "I'm not afraid of any damn hero."

"You shouldn't be. We heroes aren't meant to be feared, but to be loved." Jeanist then used the same technique as he used with Osamu by weaving the threads silently around Aiko's limbs.

But they were immediately severed as Aiko cut the threads and as she forcefully closed the portals around her, creating a circular-shaped portal around the two of them. "I know how Pro heroes work, I've got their quirks memorized as soon as I meet em'. I know your quirk involves using the threads of your clothes." Sneering mischievously, she brought a circular portal that was dangerously growing bigger and bigger above Jeanist's head. "Let's see what happens when I get em' off."

"Best Jeanist!" Several voices in unison were heard, causing Aiko to look upwards to find several Pro Heroes making their way towards them as she noticed Mt. Lady and Kamui Woods make their way towards them, Mt. Lady in particular the easiest to notice thanks to her large form as Kamui Woods began swinging from place to place using his branched limbs.

Snarling, Aiko then slammed her teleporting orb down the Pro Hero's head, closing up the surrounding portal space around him in the process, but Jeanist used this opportunity to snag the buckle suspending the Shamisen upon her back using his now-free threads and release the strap, causing her instrument to clatter to the ground. The girl's eyes growing wide in fear, Aiko quickly reached for the guitar, clutching it protectively to her chest as Jeanist managed to throw her off and caught her wrist. Snarling, Aiko used a portal to sever the bonds but Kamui Woods then wrapped his branches around her body threateningly, squeezing her mercilessly.

"I won't kill you, but I won't hesitate to do what's necessary to restrain a criminal." Kamui Woods responded forcefully as Aiko groaned in pain.

"I… won't submit to the fools who dress up in stupid costumes to please their ignorant crowd… I'll beat you all and teach you all a lesson…" Aiko growled but that only tightened Kamui Woods' grip.

"Oh dear, Nishiya, you're getting carried away again. She's just a little girl." Mt. Lady coaxed him, attempting to soothe the tension as she hunched over to get a close glimpse of the scene. "You wouldn't want to take the credit of accidentally killing her, now, would you?"

"I'll take it from here." Jeanist stepped forward, flicking his fingers again as threads began weaving from his clothing. Aiko snarled at him and with her draining strength she created another portal- but this time instead enveloping her arms and limbs through the branches of Kamui Woods' grip.

"She's- she's gone!" Kamui Woods cried in disbelief, staring at his now-empty branches.

"Well maybe if you weren't so adamant about restraining her and getting all the credit for it instead of handing her over to me, then she wouldn't have escaped!" Mt. Lady snapped, crossing her large arms.

"Well if you weren't being so showy and LARGE in the MIDDLE of a WINTER NIGHT then I would've given her to you!" Kamui Woods snapped. "And I know YOU care only about getting MY credit when it comes to showing off when it was MY idea all along that we should help Jeanist!"

"You care only about getting all the credit too, you know! So you're guilty too!" Mt. Lady snapped at him.

"Am not!"

"Are too!"

"Am not!"

"Are too!"

"All right, cut it out, you two. Right now, we all are capable of taking credit. But we, as a team will work together to find this girl and the rest of her crew. Now let's move." Jeanist ordered.

Mt. Lady yawned, her eyes growing dreary with wear. "I'm getting sleepy. What time is it?"

"Are you kidding me?!" Kamui Woods sighed, rubbing his wooden forehead as he followed Jeanist, Mt. Lady stomping loudly behind him as he muttered curses to himself. "Why do I work with this woman?!"
