What If, Gehenna

A final farewell

Yukio, possessed by the almighty Lord, Satan, stood in pride. He was finally getting his prize. Assiah. Shura slouched against a wall, Bon and Shima tending to a barely concious Koneko. Izumo looked on, terrified, along side Shiemi. Her, Shiemi, eyes widened, catching a sudden breathe and holding it.
"RIN" She screeched as the dim flamed X-Wire exorcist stood up, unsteadily.
Satan hit him hard, to an extent where Rin was dripping with blood, swollen. Battered.

"That's...my brother.." He whispered to himself as he rose to a crouch. "That's my brother!" He roared. His flames consuming him.  Despite the beating, he was still raging. His birth father using his brother, an amazing Exorcist, Doctor, friend, against the world he loves and grew up in. Rin would never forgive himself if he couldn't stop Satan from destroying everything he has grown to love. He knew Yukio wouldn't forgive himself either.

"Satan." Rin called. Satan turned his gaze to Rin, postponing his reign. "Let's make a deal." Everyone turned to Rin in shock.

"A deal? Go on, Son." He laughed hysterically as he empathised 'Son'.

"You leave Assiah. Never touch it again. Do not try anything against Assiah or anyone living in Assiah. Including you leave my brothers body. And in return..I will return to Gehenna with you." Rin spoke out clearly. He put on a brave face, but in truth, he was terrified. His classmates, Shura and Kuro retaliated in disbelief of what Rin stated. Wanting to change his mind.

"NO. Rin, don't be stupid! We'll think of something else!" Shura exclaimed.

"Rin please don't! Just listen to Miss Shura!" Shiemi screamed. Tears whelming up in or beautiful, sad eyes.

Rin lowered his gaze to the floor as he balanced himself on his feet. He didn't listen. He couldn't listen. To hear his friends denial put him off. He wanted to do this. If he wasn't sure this was the only way he wouldn't be doing it.

"My....well. I guess I will take you up on the offer." Satan grinned. He stepped forward. He eyed Rin up and nodded.
Just as he nodded, Yukio collapsed to his knees, the flames dispersing. Yukio looked up to his toppling brother.

"Rin? What are you...?" Yukio murmured

"RIN" The others yelled, running to Rin and Yukio. Bon grabbed his shoulders, Shima helping Koneko walk.
Shura skidded to Yukio ' side to help him, looking up to Rin as she supported Yukio.

"Rin don't do it!" Shura yelled "Are you stupid?!" Yukio was kind of in the dark.

"I won't break my promise." Rin mumbled. "Yukio. Bro. Look after Shiemi and the others, okay.". Shiemi burst into tears embracing Rin, burying her face in his chest.

"Yukio. Rin he's....He's going to Gehenna with Satan." Shura added, quietly. Yukio's gaze dropped. His breathing rate decreased. His brother.

"NO Rin! You can't! He possessed me so I should go.  I should pay for my sins--" He was cut off abruptly by Rin carefully prying off Shiemi and lunging down to hug his brother.

"You are needed here. You are respected. You are loved. Help All these people. All our friends. I'm no where near as helpful as you. Anyway," He let his brother go and held him back by his shoulders and smiled "I made the promise." He said with a cheesey grin "Imagine the grounding I'd get if I broke the promise I made with 'Dad'." And chuckled with a bright smile. Yukio was struck by how grown up Rin seemed to be, yet still his childish self.
It was refreshing.
Yukio embraced his brother trying to hide his forming tears.

"Please come back. I need you." The exorcist whispered into the brave boys ear. Rin returned the embrace before standing. A gate to Gehenna formed a few feet before Rin. He staggered over, an obvious slice through his leg being a handicap.
He hesitated to turn, but he did. Getting one last look at what he may never see again. The girl he loves. The only family he has. The only friends he has in this God-foresaken world.

He gave a big grin and waved before stepping back through the gate. Shiemi went to run after Rin, slipping through Bon's fingers. But to Shiemi's dismay, it closed before she reach it.

The blonde collapsed to the ground, bawling her eyes out. The pain from physical wounds was insignificant to the pain of losing Rin.

"Rin....Please come...home." Yukio whispered, stating at the floor.

Meanwhile

Rin struggled through the gate. Gehenna.
The land was dry and the surrounding area was almost barren. Signs of living in pits but apart from that deep caverns and canyons. The sky was a deep red. The air, far from fresh.
Serenity.
But that was crushed when the presence of the prince was picked up by all demons.
Beasts swarming from the caverns. In flight, climbing, slithering.
It was honestly quire amazing to see all these different types of demons horde.
Yet, terrifying. He didn't have his sword. He had left it behind. He figured he could just release his own flames. Which he did.
His flames flickered as the demons halted in a full circle.

Each demon bowed to the blue flames. Heads either lowered or bodies stooped. These demons were actually pretty respectful, but it's because Rin was their prince. Well, that or because Satan was his father and there was a high chance of death with no respect? Mostly likely the second reason. Satan himself probably isn't even respected. He's more likely feared. It just comes across as respect. He is king after all.

Rin looked around, his tail remaining low and close. It could be grabbed at any moment so chances weren't being taken.

A parting formed in a wave from one section of the crowd. Satan was coming in his unknown form. All we know is that Satan possesses and that body acts as his so it takes on aspects of that demon. Like that one delinquent who was shooting pigeons. He grew horns and a tail. Yet, he had a second form. A monstrous embodiment. So what would Satan look like?

Out from the towering crowd stepped a large beast. A lanky, bipedal horror. It had, what looked like bare skin, rather short black  fur across its entire body which got longer to the end of its long, lashing tail. Amongst it's 5 digit paws that resembled hands, claws. Claws on top of the digits like human nails but shaped like an animals and as strong as adamantium. This made them capable of being long and sharp, yet still useful for multiple purposes without breaking.

This beast went from slightly hunched over to standing up right as it became visible. It opened its mouth with a huge grin and a whiping pointed tongue.

"So, boy. This is your new home. However.." The beast, Satan said. "It looks as if your human body is weak and cannot sustain this land. That or you're truly fighting to become a demon" He burst into laughter as Rin's body started to burn. Rin collapsed to his knees and bellowed in pain as his body sizzled away. "I must destroy that pathetic vessel" He extended his index claw at Rin, a blue flame emoting from it and pulsing to Rin.
A roaring light emitted from Rin. Magic. From out of the light stepped another beast. A similar looking creature to Satan, yet a bit smaller and more built. Rin was now a full demon.

The blue demon looked down to look at his hands to find these large paws in place. He bared his teeth, eye lids extending and his dilated slit pupils became constricted.

"AAAARGH" Rin roared. "I didn't want this!" Satan ignored Rin's shouting.

"Hm..." Satan inspected "Something went wrong... oh well.  Over time you will become a better demon, like your own father" He empathised.

The demons despersed leaving Rin on his own. Tears filled his orbs. He looked up.

"I will escape".
