Chapter Text
The sun was low on the horizon, night was quickly approaching and the monastery was rather busy for the hour. Priests were running around, some with grenade like objects in hand, while others carried Bibles, and some had guns.
In the middle of it all the head Priest Father Fujimoto held the hands of two young boys as he pulled them towards the underground bunker. While they were obviously scared, it was far less apparent then it had been the last few days, which however is expected as they begin to get used to it all.
"D-dad?" A small scared voice said "I'm scared…" The priest's breath caught in his chest as he gazed down at the scared look on his son's face. Never would Shiro have thought the seal would have been so weak, or that Rins power would be so strong. The boys were only 4 years old and it had already become this bad.
The last 3 days the monastery had been attacked by demons non stop at night, only giving the residents the day to rest. The constant demon attacks had begun to draw too much attention to them and it was only a matter of days before they had more than just demons to worry about.
It was getting too dangerous for the kids to stay here and he knew the call had to be made.
No matter how badly it hurt him, Shiro knew the only way to keep them safe was to send them away. So while gazing down at the two scared boys he made up his mind.
As soon as morning came, the call would be made, and the kids would be moved somewhere they'd be safe.
The other child, terrified as he might be, straightened up through his shaking to face the other. "It's okay, Yukio. Dad and the other priests are really strong! They will beat the monsters just like before!" All he was able to do was smile at the kids in reassurance before turning away and locking the door.
The fight had just begun on the other side, and it was his turn to make an appearance. Pulling out a large case from behind the podium the Father opened it unveiling a large shotgun, as well as multiple grenades. Equipping himself with the gun and a few of the grenades, and he was off.
~~~
While the room they had been left in was mostly sound proof, it could only block out so much. Sounds of fighting and demons screaming out still filled the air. The young boys huddled together in the farthest corner of the room, jumping with every new gunshot or dying screech that reached their ears.
"Rin" the younger whispered. "Do you think everyone will be okay?" His voice trembled as he spoke. "Of course Yukio, in the morning everything will be just fine again and we can pretend this never happened!" Though Rin tried to sound confident there was hesitancy in his voice, but no matter what he'd never let his brother know that. The job of the older brother was to protect the younger, and Rin was not about to let his younger brother know he too was terrified.
Earlier that night their father had promised to explain everything to them, and no matter what he would be held to that promise. Even as the night came to an end, and the sun began to rise the only thing other than fear either boy knew was that they would get the truth.
~~~
It wasn't long before the night ended and the demons were already making a swift retreat. With one threat gone, Shiro knew he had an even harder battle ahead.
"Father Fujimoto, the demons have made a full retreat, we should be safe until tomorrow night"
The priest nodded and made his way to the bunker holding the twins.
The room was dim, with only a small light bulb to keep it lit in the dead of night. Upon it being opened the boys jumped in surprise as their father entered, approaching them. "Come on boys, the monsters are gone. You can come out now" he then reached to pick up Yukio and grabbed Rins hand.
They made their way out of the bunker and into the trashed monastery. The remains from the battle were quickly being cleaned by the rest of the priests. It was an instant relief for Yukio when he saw no one was injured,
"Dad, when are you going to tell us what's been going on?" Rin spoke up after they made it to the twins room. "I can explain it all to you soon Rin, I need you boys to start packing while I make a call" both boys gave him questioning looks.
"Why are we packing? Where are we going?" Yukio had begun to panic. "I'm going to call a friend and then you two are going somewhere safe away from these demons" the kids father explained in the calmest voice he had.
With that he walked out of the room.
The task was daunting, just staring at the phone was making him feel sick. It had to be done, he knew that, even so the fear was almost enough to make him forget the whole idea.
Despite himself he would make the call.
Opening the flip phone and calling the singular number saved, the phone rang. Once, twice, thrice, and finally a fourth time before… "Your call has been forwarded to the voicemail for Mephisto Pheles. No one is available to take your call. At the tone, please record your message"
Shiro instantly deflated, he knew he'd have to try again, nevertheless he can't help but feel relieved. Even though it was dangerous he at least had more time with them, and that was something he'd never complain about.
Pocketing the phone he decided to return to the twins room, knowing time would quickly run out. He was determined to spend what time left with them, even if that was nothing more than selfish.
"Ah speaking of which, its seems dear Shiro has returned just in time~"
~~~
After they were sure he was out of earshot the boys started to panic. "Where were they going?" "How long would they be staying?" "Why did dad need to make a call and leave us here to pack?" In the midst of their trepidation they missed the man who appeared in their room in an explosion of pink sparkles.
"My my how you've sure grown since I last saw you" the man spoke, startling the two young boys. "Who are you, and how did you get in here?!" The more brash of the two asked. "D-did dad let you in?" The other. "Oh no no, however that matters not!" He said with a slight smile. "I am simply here for the two of you, as a favor to your father" and it grew wider as the boys' faces began to drop.
"What do you want with us?! And what does it have to do with dad!" Rin shouted at the man. To which he laughed "What do you think I want hmm? I'm here to fulfill part of a deal at Shiro request" upon saying that they heard the door open.
"Ah speaking of which, its seems dear Shiro has returned just in time~"
"Mephisto you demon bastard, what are you doing here and why didn't you answer my call!" Shiro spit, he was beside himself with anger. "Why my dear Shiro, I was simply doing what you wanted of me" Mephisto innocently said "What ever could you be angry about?" " What could I be angry about?! YOU JUST BROKE INTO MY HOME! THAT'S WHAT!" At that Mephisto seemed to drop his smile to look at the priest pitying.
"Now how long have you known me, surely you must be used to this by now?" "I am here to take these two somewhere they shall be safe. Is that not what you wanted?" Realization swept over the priest's face, as he mentally cursed himself for his reaction. Of course he already knew.
"Take us? Take us where?" Yukio spoke in his small voice. Both him and Rin looked terrified by everything and he couldn't even blame them. "Oh dear Shiro, have you still not told them? Tsk tsk I suppose we have our work cut out for us." "Tell us what?" Rin this time spoke.
He knew this was bound to come out, he knew before the day was over he'd have to tell them everything. It was nevertheless more daunting of a task then he'd originally thought. "Well you see… mmm where do I start…." Mephisto just rolled his eyes before taking over "He means to say, those 'monsters' who have been attacking you are not quite monsters per say"
"Why yes, quite monstrous, they are indeed demons~" at which Shiro gave him a dirty look as the faces of the two boys were quite amusing. Yukio looked horrified, the monster that had been tormenting him since before he could remember where demons, real demons like out of those Bible stories they always heard. Whereas Rin just looked livid, he didn't believe a word that man spoke and he couldn't believe Yukio took him seriously. He was opening his mouth to yell once more when…
"It seems you may not believe me but oh my dear boy, it is very true, demons indeed do exist. After all, if they didn't, neither of you nor I myself would be here." There was a dangerous glint in his eyes, enough to scare Yukio from saying a word. It wasn't enough for Rin however. "What are you trying to say, you clown! Just tell us already!"
The smile returned to Mephisto's lips as he looked right into the eyes of the young Rin, eyes almost glowing. "You wish to know the truth then?" Rin nodded, and Mephisto turned to Yukio. More hesitant he still agreed with a quick nod yes before clinging to his brother.
"Rin and Yukio Okumura, you are the sons of a demon. And no no no not just any run of the mill, you are the bastard sons of Satan himself!"
Time stood still, the atmosphere in the room became tense before it suddenly. Snapped. Shiro was seething, Yukio was crying and Rin was already running in to punch the tall man. With a wave of his hand a key appeared on the desk nearby, to which he promptly picked up. At the same time the attacking child stopped in his tracks unable to move.
"Mephisto! What did you do to him!?" Shiro was unsure if he was angry or scared. Any minute now that demon would be taking his sons, and not only did he not have power enough to take him on, he also couldn't. This would be for their safety, and no matter how it hurt it was necessary. "He will be just fine, I only froze his body in time for but a moment. Couldn't have him mess up my suit~" with that he snapped his fingers and Rin was falling to the floor.
"Now we are running short on time, we must be off. May I have Kurikara now?" Mephisto said as he made a motion to check a watch that was not there. Before anyone could move Yukio turned to his father "Is what he's saying true…? Are we really the children of Satan… are we really demons like those monsters?..." The look on his face was of fear and betrayal.
"He speaks the truth… however, though your father was a demon, your mother was a human." "As so you didn't inherit any of the demon genes, Yukio you were too weak and are nothing like those demons before, you are human through and through" This did little to calm him however, as he then turned to his brother with a panic in his expression. He was always the smart one, too smart for his own good sometimes. "B-but what about Rin then… you said me... but what about him!" At that Rin looked up from his spot on the ground, most of the anger gone from his face and in its place a mix of fear and curiosity.
"Rin… well as you Yukio inherited the human genes Rin did the demon ones…" At this the fear on both their faces overtook any other emotion as their head snapped up to stare their father in the eyes. "When you were born we sealed Rins power and demon heart in the demon sword Kurikara or the Koma sword. That's how he's been able to remain mostly human this long"
Both relief and more fear spread across Yukio's face, as Rin became confused and heartbroken. He didn't know what to think of everything, and he didn't understand most of it either. His father was saying he was a demon, just like all those other people did. Mephisto seemed to catch this and interrupted. "There is little for you to worry about dear child, we shall go somewhere you both are safe and as long as the sword remains sealed nothing more will change" his voice was less playful than before as it appeared he tried to calm the boys down. This helped even in the slightest and Yukio nodded, whereas Rin just stood himself up and walked closer to the tall purple-haired man.
"Now I say we must really be going now. Say goodbye to your father, children, you won't be seeing each other again, at least not for a very long time" they both turned at that to look at their father, who was almost in tires but was holding it back for their sake. Yukio ran up crying and embraced the priest who gladly hugged him back. Rin however couldn't even look at him and so Shiro walked up and embraced Rin. "I am so sorry for lying to you, I never meant to hurt you and I don't want you living the rest of your life thinking I did. I love you and Yukio so much, and that's why you have to go" he turned to Yukio "You both have to look after eachother and remember that I will never stop loving you guys"
With that he let go of Rin and backed away. "I will grab the Koma sword for you" and he departed the room. "Now then I shall explain to you what we shall be doing" The boys looked at Mephisto a little skeptical, but didn't say anything and let him continue.
"We shall be going to a world far from here, one with far less demons than this one. It is ruled by another supernatural being known as Truth, who you shall meet shortly." "Do we have any questions?" Yukio's face lit up with "Another world?!" His question. "Yes yes, follow along"
Before Mephisto could continue however Shiro returned with a decadent sword in hand, still sheathed. As soon as he walked into the room Rin beamed, a complete one eighty from before. Mephisto could see the way Rin's eyes landed on the sword, even sealed with no way of truly understanding what it meant. You can't keep a demon from their heart, and Rin subconsciously knew this.
He smiled slightly at seeing the young boy's eyes follow the sword as he received it from the priest. "Come along children, we shall be leaving now. I don't want anyone left behind, because I will not come back for you." With that he turned to the door, inserting the key from earlier.
"You boys be strong, and take care of eachother ya hear?" Their father was moments from tears, but still stood strong and smiled to reassure them. Yukio nodded and slowly walked closer to his brother "I love you dad" he said before grabbing Rins hand.
The door opened and on the other side was a pure white abyss. It was enough to send chills down Yukio's spine, he clenched his brother's hand tighter. "Come along, come along, we have already wasted far too much time" Mephisto's voice cut in. With that he ushered them through the doorway into the endless white.
~~~
White continued on forever, no matter which way nor how far you traveled changed that. Mephisto led the twins through the void, while neither party uttered a word.
Eventually the whiteness gave way the slightest bit, revealing a large door. Sitting in front of it was a being as white as the world around them with a row of sharp teeth pulled into a smile facing them. Yukio knew immediately they would have to pass through this door, whereas Rin stared at the being in complete awe.
"I have brought the two children" Mephisto said to the white being, to which they didn't even look at the man. "One name you might have for me is the World, or you might call me the Universe, or perhaps God, or perhaps the Truth. I am All, and I am One. So, of course, this also means that I am you." "You are entering my world, and as such you must obey my rules." The mostly featureless face turned to face Rin. "As long as the demon stays within reason, we shouldn't have a problem."
"You are permitted to enter, just don't make me regret this" The beings voice echoed as the large door opened. Stepping out of the way the white lifeform smiled an unsettling smile at the group as they passed by.
~~~
The other side of the door was both familiar and strange, it was land and sky like in Japan, but everything was so quiet and peaceful. It must have been more similar to the rural areas of their homeland. Yet it still felt different, from the land itself to the cleanliness of the air. Architecture seemed different as well based on the two houses that stood at the end of the road in different directions.
"Now then, do follow me~" Mephisto sing-songed as he started off for the house on the left. It was a rather tall house compared to the other, and had a large tree out front. The path seemed well used and the closer they got it seemed as though random craters littered the trail.
From the inside they could hear people laughing and playing, as well as the occasional sound of electricity, as blue lights illuminated the windows. It was clear there were at least two people inside.
Mephisto knocked in what sounded suspiciously like a song. A moment passed before a woman opened the door.
She had soft brown hair, held in a low and loose ponytail. Her eyes were a green that almost looked blue, very similar to Yukios own. She looked very gentle and kind, with a sweet smile on her face.
Behind her there were two boys about the same age Rin and Yukio, who were holding onto the woman's legs. Both had golden yellow hair and eyes, the smaller one more so than the taller.
"Mr Pheles! We have been expecting you!"
