Aether

n an underground boxing arena, the crowd roared with excitement, eager to witness the young fighter who had made a name for himself by challenging boxers across the continent. This time, he had arrived at this ring as a challenger once again.

Standing in the blue corner was a young man with brighter shade hair, a well-proportioned build, and modest muscles. He wore sleek black boxing gloves adorned with shiny gold stripes that gleamed under the spotlight. His loose black shorts, trimmed with gold at the edges, swayed slightly as he shifted his weight. The elastic waistband sat just below his navel and was emblazoned in gold letters—outlined in white and black—with the name: “Aether.”

"Alright! Today, I'm definitely going to win!"

Aether shouted confidently, raising his fist to the crowd, drawing an even louder cheer.

Just then, his opponent stepped into the red corner, prompting the referee to signal both fighters to put in their mouthguards in preparation for the match.

Aether nodded and turned toward his corner, spotting his mouthguard resting neatly there—large, black, and streaked with gold.

"Hnggh... Alright, time to get serious... ugh... mm..."

Taking a deep breath, Aether clumsily lifted the large mouthguard using his gloved right hand and awkwardly shoved it into his mouth, drool starting to drip down his chin. Despite his experience in countless fights, there was something oddly charming about how ungracefully he struggled with the gear. A nearby monitor zoomed in on him just as he inserted the mouthguard, causing many women in the audience to swoon.

"Mmm... hff..."

He tested his breathing. The mouthguard sealed off his mouth completely, forcing him to breathe solely through his nose. The gear was clearly visible through his lips, making it impossible to miss. Aether bumped his gloves together, then leaned against the ropes, trying to steady his breath and adjust to the mouthguard while the bell was just seconds away...

Lumine

On a calm and quiet day, Lumine—a brighter shade haired young woman with a bob haircut and straight bangs, her hair trailing down to her shoulders—received a mysterious challenge from an anonymous man in the city of Inazuma. She accepted.

Following the invitation, she arrived at the designated location—a rooftop of a building. As she stepped into the open, the sky glowed in deep purples and oranges, the colors of sunset fading slowly beyond the city skyline. A gentle breeze played with the ends of her hair as she scanned the tranquil surroundings. Despite being high above the ground, the world felt peacefully still. In the center stood a boxing ring, surrounded by towering buildings and blooming sakura trees, their petals occasionally drifting through the air.

On the ring stood a man—presumably the one who issued the challenge—already waiting in the red corner, leaning casually against the ropes. As Lumine arrived at the rooftop entrance, he turned to look at her.

"Ah, Miss Lumine. You've finally arrived. Hurry and get ready, before this beautiful moment slips away."

"R-right… I’ll be there in just minute!"

Lumine replied with a mix of nerves and determination. Standing just by the entrance, she began changing, revealing the boxing outfit she had worn underneath. Her top was a white sports bra accented with black stripes. Her shorts were white with gold trim, and her name—“Lumine”—was embroidered neatly in the waistband.

She pulled out her boxing gloves from her shoulder bag—black with gold streaks—and slid her hands into them. Using her teeth and jaw, she tugged and tightened the laces until they were firmly secured on both wrists.

She bumped her gloves together with a soft thump, checking their fit. Then, she reached into her bag once more and pulled out a large white mouthguard with yellow streaks along the edges. Holding it between her gloves, she stared at it for a moment.

"Whew… still not used to this, but… here goes."

With a steady breath, Lumine raised the big mouthguard to her lips and slowly pushed it in using her gloved hand. As it slid into place, her cheeks puffed out slightly. Her lips parted just enough to reveal the guard's presence, and her breathing grew heavier as her mouth was sealed shut by the unfamiliar fit. Saliva began to gather and dribble from the corner of her mouth.

"Hhh… hhh…"

She let out a soft, breathy sound, adjusting to the discomfort, before glancing toward the mysterious man who still waited patiently in the ring.

But then—she noticed the light. The sun was disappearing fast. This was her moment, and she wouldn’t let it slip by.

Without hesitation, she smacked the mouthguard tighter into place with her right glove and broke into a run toward the ring. She climbed up and stepped into the blue corner.

"Leh’uh… ahh leh’uh geh shhtahhh-ted…"

(Let’s… ah, let’s get started…)

Lumine spoke through the muffled barrier of the mouthguard, raising her gloves into a stance. She stood now, silhouetted perfectly against the last rays of the golden sun.
