…

Dishevelled and muscle aching they ran down the empty corridor that lead towards Mephisto's office. Steps echoed in the halls ominously, sun setting sky that now was slowly darkening with hellspawns all over it didn't help the terrible feeling that kept on sliding down Rin's back. Probably everyone's back.

They didn't speak, they just ran ahead.

Breaths mingled as they went on their way, an icy cloud of fear fast on their heels trying to consume them all but Yukio, his Yukio was set on getting to Mephisto first thing and so they did.

In all honesty, Rin never thought that their academy could seem so bare - there was no one around to witness the apocalypse that just begun. The pentagram shone on the sky, illuminating oh so ironically beautiful sunset, painting it black – swallowing the world in it.

For now it just begun, there was still a chance for them to close Gehenna's gate just like the last time. The problem was, this time was different. Somehow, someone managed to open up the gate without their hellish blood and that didn't promise anything good.

Gulping he inhaled through his nose deeply, scanning the sky once again. There were two visible lights shining in the distance from what they've seen already – that meant they probably used the doorways.

If so... then Yukio was right. It was supposed to be a pentagram.

A faint siren resounded outside and that made him falter in his step. Unprepared for it, Bon ran straight into him and Rin growled under breath startled.

"Well, shit, Okumura. What do you stop for?! We need to get to Pheles-san as fast as possible, stop dwelling—"

Glaring at his friend, Rin opened mouth. "Do you hear it?" he asked catching breath. "They turned on the sirens—"

Bon's step wavered as he also listened on. Shiemi who happened to be the last one caught up to them, looking between them with a mixture of confusion and impatience on her face.

"What are you waiting for!" she mentioned walking past. "We need to keep going!"

Rin understood her worry, the importance of them getting to Mephisto but the sound of the sirens—it meant. "It's a disaster" he stated curling hands into fists. His heart was pounding and blood rushing in ears. "They've turned on the sirens—you know what that means..."

Shiemi gasped slightly as she stopped, turning towards glass-less windows. "The calling" she deadpanned sombrely her face scrunching. She listened in, hearing the sound nobody should ever hear. Never.

"It's the end, we need to stop it before it spreads" Rin concluded sweating. "Shit. Fuck. It was our responsibility as exorcists to save people—and now, this goddamn shit means 'everyone for themselves'; this won't end up good."

Shiemi agreed with it, nodding. "People are not prepared to fight hellspawns on their own. Most doesn't even know such things even exist—ah!—my mum, I need to save my mum!"

Shaking his head Bon started to walk on. "We have only one shot at this thing. If we close the gate it will be all over—we won't be able to save everyone but we can try to minimize the loss—we will have to make a stand, whatever it takes."

Nodding Rin knew that Suguro was right, the fight was going to be a tough one – they would probably have to make a sacrifice or two on the way; even if it meant—he gulped at the thought of a possibility that they might need to kill Yukio if...

"Y—yeah."

Shiemi had tears in eyes but surprisingly stood her ground. "We will close the gate."

There was a silent look shared between the three of them and soon after they ran once again ahead to catch up with the rest of their team while sirens kept beautifully singing a song for them; hopefully not a tragic one.

…

"We're here!"

Rin practically stormed into the office, Shiemi and Bon hot on his trail. Breathing heavily he scanned the room and realised they were quite grim looking at each other warily. Whatever the three of them missed wasn't good and that much he figured out just by looking at everyone's faces.

"So—what's the plan?" he asked stepping closer, his insides aching from sprinting.

Yukio kept on looking towards bookshelf, Izumo turned her eyes away at that even Shima and Koneko made that strange avoiding dance only to not reply to this question. They all looked so uncomfortable and—devastated.

"Uhm—" he tried again, looking at each and every one of them. "Alright, what did we miss? It's bad, isn't it?" he concluded at the twitch that Koneko made. "Whatever just bring it on, we will deal with whatever it is."

Mephisto who was apparently ignored for the time being, stood tall from behind his desk and put on his tophat. "There is something you should know, Rin-kun" he started taking a hold of his umbrella. He looked at it closely, turning it around in hand. He seemed to be fascinated by it for some weird reason. "The sirens call. The thing we will have to stand against is much stronger than the last time—"

Growling Rin bared his fangs, tail whipping behind him angrily. "I know you shitty fluff-clown, we heard them on our way here. What I asked was what is the plan... How do we close the goddamn gate?"

Narrow of Mephisto's eyes was concerning. Then tip of his umbrella hit the desk with a loud crack, splitting the wood where it touched the surface. "There is a lot more on the stake this time. Not only our lives but entire worlds. Take a look outside and see for yourself if you don't believe it. Anyhow—we have a gate to close and five doorways that lead to it's opening I believe" here he leaned over his umbrella, cocking head in their general direction, thinking.

"All of them need to be closed beforehand. The Gate—" turning swiftly around he pointed his trusty umbrella towards blue pentagram that illuminated sky "—we should be able to close after the doorways are destroyed, as you all can see they are supplementing said gate with hellfire. However—this needs to be done as soon as possible I believe. The longer doorways are open, the wider the gate opens, the stronger influence Satan has in Assiah."

Sullen faces stared at Mephisto. Rin's tail kept on twitching.

"Okumura-sensei, how do you feel?"

Question was so surprising that even Yukio was temporarily awed. He composed himself pretty well though in seconds, his face closing back up in an instant. "I feel fine, Pheles-san."

Mephisto smirked to that. "How about your link with Gehenna?"

Now at that Yukio visibly tensed, at what Rin also did wondering about exactly the same thing. He prayed that there was no danger from his twin, he prayed that Yukio won't say he can still hear their father trying to convince him. But of course all of this was brushed away with the very next thing he said.

"I—he—speaks. It's faint but I do hear him. He's laughing—he's laughing so much at us."

Crunch of wood filled the office.

"I see" said Mephisto taking off umbrella from the desk. "Anything else? Something that might help us?"

Yukio scrunched his face as if in pain and then trembled. Rin turned around to him in an instant.

"Yukio! ~Yuki-chan! Sensei..!"

His brother shook his head at them, straightening back. "It's okay—I'm fine" he deadpanned even though there was a sweat sliding down his chin. "I think—he laughs 'cause he says it's impossible to close the gate" he managed barely, his eyes getting wider as he spoke. "There is no eye in Assiah... it's—on the other side."

Mood turned even sourer after this. The silence and faint sound of the sirens were everything that filled the office. Those words felt like the proverbial last nail to the coffin. Even he, Rin understood what it meant. Whoever will want to close the gate won't be coming back from there.

Subconsciously everyone gazed at the black rift that kept on growing bigger with each passing second. With shuddering breaths they realised that indeed the gate hasn't got an eye in the Assiah, it more reminded them of this huge black hole that kept on sucking inside any light it came across.

So it was it, the end of humanity as they knew it.

Mephisto was glaring from a corner of his eye, pondering. When he finished he tsked, narrowing his eyes dangerously. "Foul move, father." Then he sighed, scratching at his forehead until he clicked his fingers as an idea struck him. "So we need something that might be able to cross between the worlds—or rather—someone" he concluded, looking back at two Okumura's who stood silently. "For everything it's worth you boys have the most chance to get onto Gehenna's side and come back unscathed."

Rin refused, his fear and anger flaring out. "What the hell?! Why us? Why don't you go back up there where is your place and close the damn thing yourself?! It's probably your fault it's even opened in the first place!" he lashed out, his eyes involuntarily reddening. "Why won't you say anything about Lucifer?"

"Lucifer?" asked shocked Konekomaru, listening with the rest of the exorcists intently.

"Yeah, Lucifer, and while you're at it tell me where is Nakamura now?"

Exhaling tiredly Mephisto swished around his umbrella. "Lucifer is our brother and he paid me a visit some time ago. He's gone now, so you don't have to worry about him anymore. As for miss Nakamura... she's in a safe place."

"Safe place?" piped in Yukio with interest. "Why is that?"

Rin nodded to that. "Exactly, why is that fluff-clown?"

"It is so because she is a danger to everyone she meets. You don't want anything bad to happen to either of you, now do you?"

Growling a bit more under breath Rin pushed on. "How? How is she dangerous?"

Answered him surprisingly Yukio. "She's a demon isn't she, a hellspawn."

"Hah?"

Mephisto's eyes twinkled at that mischievously. "Now, how would you know that, Okumura-sensei?"

Yukio shrugged it off as nothing back then but it all just fell into place. "She—I guess—She must have saved nii-san."

Blinking dumbly at that Rin rounded at Yukio. "Ha—ah? How, when?"

His brother racked hand through hair before he settled on telling it up straight. "Do you remember your mark? How you almost died when banshee attacked you for a second time? You—I think you actually did die—on fourth day however I found a hellspawn over your bed nii-san. It was a girl for all I could tell and she made me to choose—you die or live. I, of course shot her and she escaped but—you woke up then."

A flash of memory made Rin gasp. "I remember! So—that means—she was the one who..."

Another flash of memories bombarded him. The other set, the one he didn't want to remember but he did nonetheless. They were so painful, so real. But it was impossible for her to know, it must've been a mistake, a trick. Leaving that trail of thought he clenched his fists tighter.

"Who was she really for you, Pheles-san then?" asked Izumo cocking her head to the side. "As far as I remember there indeed was a girl, you introduced her as your niece; Nakamura Kyoko."

Shima got enlightened then. "I know, I get it now Rin!"

Rin chuckled under breath at that. "Better later than never."

After that all eyes settled on Mephisto who narrowed his own a bit more, tsking. "Exactly who I introduced her as, my niece."

"Do demons can have babies?" murmured under breath Koneko pondering.

Shiemi blinked her eyes to that. Izumo just shrugged the matter off. Bon however sighed under breath before he spoke.

"Yes, it is possible, isn't it?" he stated looking pointedly at two Okumura's. "We have a proof right under our noses, don't we?"

Rin twitched in place, feeling so openly judged by everyone. Yes he was a hellspawn himself, therefore there must've been a way for demons to have spawns of their own. A half-demons like himself. What if there were more of them but they never knew because they didn't flaunt it all over the world? What if he was simply unlucky enough to be born between ranks of exorcists and there might been hellspawns all over the world that had the luxury of living a normal life?

"Impossible" cut it Yukio. "Both me and nii-san were born by accident."

Izumo frowned upon that. "Well, yes, Okumura-sensei but what if other demons were somehow able to transfer their—hellfire—onto a living human being by soul-bonding? There is a lot of possessions as we know it so we can't completely rule this out. It's all in the air in the end."

Koneko agreed wholeheartedly with that.

"Well then, what about people that weren't fully possessed? What if a person makes a pact with a demon and is only a partially a vessel?" continued Rin, worrying about their blonde friend that started to squirm uncomfortable in the corner of the room. "What about their blood, their soul? What about their children, will they be half-demons?"

Shrugging Izumo made a huge eyes. "I don't know, it's all hypothetical. How should I know?!"

Shiemi grumbled something under her nose to that settling at shaking her messed up blonde hair. "It doesn't matter. We have to close the gate as soon as possible!" she injected puffing up her reddening cheeks. "If we close it we won't have to even consider it, right?"

A bit uncomfortable feeling fell over everyone in the office.

"I guess" concluded that topic Shima scratching at his neck. Rin could only grid teeth in aggravation at that another question without answer.

Moving on with the conversation Yukio turned his full attention to their guardian. "Then so how do we get to close the gate? If I am correct we need to close at least five doorways before we will be even able to get close enough to the gate itself."

Mephisto nodded silently, narrowing his slanted eyes at young exorcists. "If I am correct then yes. We will have to close them up soon enough, the gate keeps on growing for as long as they stay open."

Nodding Yukio clenched his fist at sides. "Then we need five capable groups to take them out."

Tipping his hat Mephisto chuckled. "Oh I think you are more than capable of this" he deadpanned, looking around every face in his office. "There's enough of us to do it in time."

"Wait!" Rin interjected to that, a chill sliding down the back of his neck. "You can't possibly mean—!"

Yukio sighed turning around, facing everyone. There was a brewing storm behind his teal irises. "We can make it if we split up. Groups of two should be enough I think, hopefully."

Growling under breath Rin stepped up, his tail swashing behind him. "You can't be serious!"

"It's the only way I believe Okumura-kun, your brother is right."

"Now, you—you shut up!" he barked back at their guardian. "So we're supposed to stick our necks out while you do god-know-what is that it?!"

Surprisingly Mephisto tsked disappointedly. "Oh sorry, I forgot to mention you need me to keep the gate at bay. I suppose I might be too busy trying to contain the hellspawns while you will be closing the gate."

Heavy breathing filled up the office as Mephisto's words sunk in. Involuntarily Rin grit his teeth even more, it looked that Mephisto was their shield in the oncoming battle hence the confidence in his or his brother's departure to close the main gate.

"If so then who'll take care of the last doorway?" asked suddenly Koneko, his fingers pointing up. When everybody's eyes fell upon him he sweatdropped little. "I mean, there's five doorways and the main gate, right? Given we will go in two's there's not enough of us for all of them?"

Blinking Izumo scrunched her brows in contemplation. "Actually, Koneko is right."

Bon crossed his arms, thinking. "It depends on teams as well. I mean we could just draw who do we end up with—"

"I can go with Amaimon" cut in Shiemi with unusual confidence in her voice. "That would be first pair, wouldn't it?"

A holler of 'no's' followed blonde's admission, both from young hellspawns.

"That's a definite no" stated coldly Yukio. "I won't let you face the danger with only a demon by your side."

Shiemi inhaled through her nose, yanking eyepatch from her face. It landed on the floor. "I think I'll manage. Besides I trust Amaimon to keep me alive until it's all done with."

"It's not that, Shiemi" piped in Rin with sour face. He didn't like the way their friend kept on trusting their enemy. "He's a demon, a demon king and the last time—"

"The last time miss Moriyama made a concious decision to become a vessel to our brother" mentioned with a slight disdain Mephisto. "As much as I don't like it either, I think we have to respect miss Moriyama's will."

Shiemi nodded her head gladly to that. "Thank you, Mephisto-san, I appreciate it."

Baring his fangs Yukio sighed in defeat. "So we have first pair then. That leaves three more."

"Four" corrected again Konekomaru. "Both you Okumura's will have to stay behind to close the main gate when it's time."

Blinking Rin shook his head. "There's no way I will let you all go alone—!"

"You will have to" concluded Bon. "Koneko is right, we need you two to get into the eye of the storm so to speak, even if it means there's going to be no fighting for you." Seeing incoming glare sent his way Bon chuckled under breath. "Oh don't worry Okumura, we will be fine, it's you you should worry about. Who knows what you will find on the other side."

"—or if you will be able to come back."

Izumo's words bounced around them in silence, slowly sinking in.

"I mean, we still need rest of the pairs!" piped in Shima his lips quirking at the corners. "I choose Kamiki!" he added as if in afterthought. When he caught a glare towards himself from said girl he smiled charmingly. "What? Nobody said anything how we choose our partners. Shiemi-chan is taken already, Kamiki you were the only available choice—ow! Stop hittingmewoman!"

"I'll give you the only available choice Renzo!"

Chuckling under nose Rin happily etched the view of his friends bickering over that stupid choice of words in his memory, if might've just as well could be the last time he was going to see them so carefree.

"Alright, second pair Shima-san and Izumo-san" concluded Yukio, breaking the pair from each other. Then his teal eyes fell onto Konekomaru and Bon. "Third pair Koneko-san and Bon-san" he added, looking back at their guardian. "We need two more groups. We're short in people—"

Chuckling Mephisto turned around towards glass-less windows pointing at a very visible, a very flickering blue light. "We're in luck, Shura-san already is taking care of the first doorway it seems" he said nonchalantly, smirking. "That'd leave one last doorway to take care off—and I volunteer."

With ticking brow, Rin sneered under breath. "You just said you'll try to contain the gate didn't you?"

Shrugging it off, Mephisto tsked before he smirked glancing back at older Okumura, licking his lips with a wicked intent. "Who said I won't be able to manage that feast? You cannot truly comprehend the power we kings posses."

Gulping lightly, Rin felt as his tail went completely stiff with mortification. Fear was becoming more prominent in his stance with each second and apparently Mephisto's words didn't help his situation. That silent, unasked question was at the tip of his tongue, hovering: how powerful Mephisto truly was?

Nodding in acceptance to such offer Yukio glanced around the office. "So that would be it" he stated before he glanced back at their guardian. "We need to pinpoint the exact position of the doorways. I already have a map in our dorm room—"

Cutting him off Mephisto clucked his tongue moving umbrella into the air. With a quick 'eins, zwei, drei' a worn down map appeared in office, landing onto cracked desk. It's edges were curled and a huge yellow-brownish stain adorned the middle of the space where carefully drawn lines were.

"Well then, shall we?" he asked everyone, smiling and pointed towards the map.

Everyone looked over each other and then nodded, knowing well enough that it was their the most important mission as an exorcists and as a human beings.

Because if they were to fail, who'd save the world?
