Eren and Lucifer trekked across the ashen landscape, Lucifer had a skip in his step. As if he was an eager school girl, ready to tell her friends about her latest crush. His blonde hair flowed elegantly behind him, swaying with every step.

Eren on the other hand trudged behind him, struggling to keep up with his pace. The ground was soft beneath his feet, like walking through wet sand. A faint wind blew past them, carrying with it a bitter scent.

The pair arrived at a grandiose arena, complete with stone pillars and arched entranceways. White concrete walls lined with veins of gold, intricately carved with archaic symbols. Although the white colour of the stone was faded, cracked, and chipped away in many places, it stood out like a sore thumb in the ashen wasteland. As if it was taken from another place, another time.

Lucifer strode confidently towards the centre of the arena, gesturing for Eren to follow him. The white sand harder here, crunched beneath his feet as they walked.

"So, this is where I'll be training?" Eren asked, breaking the silence. Lucifer smiled proudly,

"This is it! Pretty impressive, isn't it? Many reapers have come through here. Their blood spilt upon these sands." His eyes sparkled with excitement, his voice brimming with passion.

"It looks like a dump." Eren stated plainly, unimpressed by the arena. The interior is as decayed as the exterior, red sand covered the stone stands, the walls cracked and faded.

"I call it personality." Lucifer countered confidently, ignoring Eren's disinterested tone.

"My dear Eren, you are in for a treat... For I Lucifer, shall be your trainer. Your teacher. Your MASTER." Lucifer proclaimed proudly, particularly emphasizing the last word. He took off his coat and tossed it aside.

"What? Why?" Eren asked incredulously. Lucifer seemed surprised by the question, tilting his head to the side. "Don't worry; I don't bite. Well, that’s a lie..." He corrected himself quickly, flashing a devilish wink.

Before Eren could respond to the reaper’s innuendo, he charged at him. Knocking him flat on his back, pinning him down with a firm hand. "Get off me!" Eren yelled angrily, struggling to free himself from the reapers grip.

But Lucifer refused to budge, not even moving an inch.

"Eh, feisty. I like that." A sadistic smile, amused by Eren's resistance.

"I said get the fuck off- Euph." Lucifer had placed an oddly shaped ‘fruit’ into Eren's mouth. The taste was revolting, a mix of sour, tangy, soft, and hairy. Like a wet ball of fuzz. Eren could almost swear it wiggled down his throat, rather than sliding down.

"Wha... What the fuck is this!" Eren gagged, frantically wiping his tongue with his hands. Trying to remove the disgusting sensation.

"It will help with your transformation; you'll thank me later." Lucifer explained cheerfully.

"I want another trainer." Eren spat, grimacing at the taste in his mouth. Lucifer stood up and pouted, putting his hand on his hips. "How rude, I'm the best of the best. The crème de la crème." Lucifer boasted, placing a hand over his chest dramatically.

Stolen story; please report.

"I thought you were going to teach me how to fight. Not flirt with me and stick weird things down my throat." Eren snapped back, standing up and dusting himself off.

Lucifer raised his eyebrow, smiling curiously. "Aren't we a little bit impatient? It's only the first day, dear Eren."

"No screw this I will go ask one of the other reapers." Eren turned around to leave.

A sudden gust of wind rushed towards Eren, without thinking Eren grabbed Lucifers shin, mere inches from his temple. "You will not leave this arena until I say so." Lucifer spoke in a darker tone, the mask of flamboyance and joviality dropped completely. His narrowed eyes burning with cold fury.

----------------------------------------

Lucifer withdrew his foot quickly, spinning around and performing a roundhouse kick to Eren's head.

Once again, Eren blocked it instinctively, without even realizing it. His mind felt hazy, filled with adrenaline and anticipation. Lucifer launched a flurry of kicks at him, each one getting progressively faster and harder.

The speed eventually caught up with Eren's defences, a direct blow into his torso; A loud crunching noise rang out as the kick connected with Eren's ribcage. Eren's body was thrown back several meters by the force of the attack. His feet kicking up clouds of dust as he slid across the sand.

"Ughh!" Eren let out a strangled gasp, clutching at his side. He rolled over onto his stomach, spitting out blood onto the ground.

The blonde reaper's expression returned to its usual playful demeanour, "I must say, you have a strong survival instinct. A perfect starting point. A sculpture I can… mould." Nearly bitting his lip off, head a buzz with crude thoughts

Eren spat out another mouthful of blood, wincing in pain as the bitter taste filled his mouth. "Yeah..." He groaned weakly, struggling to stand up. "You know you remind me of my younger self, bold, brash and sexy..." Lucifer giggled playfully as he continued to talk about himself.

With regained breath, Eren charged at Lucifer, determined to land a single hit on the self-absorbed reaper. However, Lucifer effortlessly caught his fist in his palm. "Ah-ah-ah." Lucifer wagged his finger disapprovingly.

"Didn't your mother ever teach you it's rude to interrupt-" Eren threw another punch at him, aiming for his smug face. Only for Lucifer to dodge it effortlessly, ducking beneath the attack.

"My, my... Someone is getting feisty." Lucifer purred, stepping away effortlessly. "I like it when you take control."

"Stopping saying that stuff" Eren growled flustered once again, throwing several more punches at Lucifer. Each one parried with ease. His punches were a plea for seriousness, a purpose not just a playful wrestle.

As the punches rolled on Eren noticed something, Lucifer’s left side was starting to slow down. 'An opening.' Eren thought to himself, taking advantage of the momentary gap in defence.

He aimed for Lucifer's face, connecting a clean hit straight into his jaw.

Lucifer stepped back, stunned by the blow. "You, hit me." He touched his cheek gingerly, rubbing the spot where Eren had struck him.

Eren smiled triumphantly, a sense of satisfaction washing over him. It felt good to shut the reaper up-

"Oh my god, you actually hit me!" Lucifer squealed excitedly, bouncing around like a school girl who had just gotten her favourite idol's autograph.

"You are everything I thought you would be and more Eren Heart." Lucifer flashed him a devilish smile, "Let's end that there for today, it's been a big day" He continued.

Eren relaxed his stance, feeling a weight lifted off his shoulders. He was already tired, bruised and in pain. His whole body ached from the abuse Lucifer put him through.

"Thank you... for teaching me." He muttered quietly, averting his eyes from the reaper.

Lucifer suddenly appeared behind Eren, whispering into his ear. "Nighty night, Eren." With a quick jab to his neck, knocking him out instantly. Lucifer caught his limp body in his arms, gently lowering him onto the ground.

"Sleep well, my little dove."
