Reborn As An Extra : I'm gonna mess up everything

Today was a day of excitement and  anticipation—it was finally the day of the one-on-one duel competition. Hundreds of students flooded the enormous battle arena, their chatter and cheers echoing throughout the colossal structure. This arena was far larger than the academy's training grounds, boasting ample space for spectators and a vast battlefield that could accommodate even the most intense matches. 

At the center of the arena's uppermost section, luxurious seats were arranged for VIPs. Lilith sat in one of the most prominent positions, her commanding aura drawing attention from the surrounding professors and esteemed guests from the royal palace. Their presence added a weight of importance to the event, making it clear that this wasn't just an ordinary competition. 

Despite the lively atmosphere, a flicker of concern crossed Lilith's otherwise composed expression. She glanced at her schedule, then at the arena below, her thoughts momentarily drifting. 
"The day of the competition has arrived, but there's still no sign of Esdeath," she thought, her brows furrowing slightly. "If she doesn't return today, it will cause more trouble than we need." 

As Lilith pondered, the excitement in the arena grew. Teams that had previously worked together were now split, each student fighting for their own glory. Among the competitors were well-known names that had become the talk of the academy: Ethan, Violet, Kaelith, Claus Clandestine, Corin, Princess Ravenna, and Sylvania. 

The competition's rules were straightforward—winners would advance to the next round, climbing the ranks until they reached the semi-finals and, eventually, the grand final. Losers, however, would be immediately eliminated. The stakes were high, and every duel would be a test of strength, strategy, and determination. 

At the center of the arena, a confident second-year girl stood tall, holding a microphone-like device that amplified her voice across the space. Her energetic tone cut through the buzz of the crowd, demanding everyone's attention. 

"Ladies and gentlemen, the time has come to begin the duel competition!" she announced, her voice carrying an electrifying enthusiasm. "Our first match will feature... "Claus Clandestine" and "Emma Atherton!" 

The crowd erupted into cheers and applause as the two contestants stepped onto the battlefield from opposite sides. All eyes turned to them, analyzing their every move and expression. 

Claus, with her striking golden hair and piercing green eyes, walked onto the battlefield with the confidence of someone born for the spotlight. She exuded a quiet strength, her every step radiating poise and control. 

On the opposite side stood Emma Atherton, Corin's ex-girlfriend, whose playful smirk betrayed her mischievous nature.

She had a very big chest...cough...cough...i mean very big heart, Though her personality could be described as "naughty," her skill in battle was not to be underestimated. Emma had a curvy figure, but more importantly, she was serious right now, She knew she can't afford to take Claus lightly.

Both fighters were striking in their own way, but their combat styles couldn't have been more different. Claus had an affinity with lightning, known for its speed and destructive power. On the other hand, Emma's strength lay in her earth affinity—sturdy, unyielding, and resourceful. 

Despite Emma's confidence, the crowd murmured with speculation. 
"No doubt Claus has the advantage. Earth is weak against lightning," someone whispered. 
"Still, Emma's no pushover," another added. 

The referee, the second year girl, stepped forward. Her voice rang out clearly across the arena. 
"Start!" 

The duel had begun.
