Akazuka High School, an institution that focuses on both academics and sports, has produced numerous talented graduates who have greatly influenced society, politics, and athletics.
Thanks to its many accomplished alumni, Akazuka High School has maintained its prestigious status for over 60 years. The school is equipped with state-of-the-art facilities, each designed with the highest standards to ensure the comfort of its students.
For decades, every generation of Akazuka High students has achieved top national rankings and, on several occasions, triumphed in international championships.
In the present day, the 120th generation of students, including Mahiru Kanata, is part of this esteemed tradition. Mahiru Kanata is a strikingly beautiful girl with an albino appearance—her majestic white hair gleams, her crimson eyes sparkle like crystals, and her skin is flawless, smooth, and soft.
Her enchanting, elegant face seems sculpted by divine beings. This morning, Mahiru Kanata makes her way to school dressed in the distinctive Akazuka High uniform.
The blazer she wears is the hallmark of Akazuka High students: resembling formal attire, it features a dark navy blue color, golden buttons, and a wide white semi-bow tie. On the right shoulder is the school emblem, shaped like an eagle soaring toward the sky. Complementing this is a white, wide pleated skirt with light blue stripes.
Carrying her school bag, Mahiru Kanata walks to school, lost in thought about her upcoming biology lesson on the adaptations of living organisms.
"That lesson... its theories are so complex... Haaah~," she mutters with a sigh. After walking for some time, Mahiru Kanata arrives at school earlier than most.
Entering the grand, towering school gate, which stands open wide, Mahiru steps into the vast school grounds and heads toward the large main building. She makes her way to Class 1-A, where she and her peers study.
Upon entering the classroom, Mahiru, expressionless as ever, begins her day by cleaning the room and wiping the blackboard, as it is her turn to take on cleaning duty.
Arriving early, she starts cleaning the entire classroom alone without waiting for the other students assigned to help. Sweeping the floor of Class 1-A, she hums a melody from a song she loves.
Mahiru enjoys several pieces of music, such as A-Live by Lycoris, Sparkle from Kimi no Na Wa, and others.
After sweeping, she continues by mopping the classroom floor while mentally rehearsing the theoretical formulas of morphological and physiological adaptations in biology.
Her mind is filled with concepts of adaptation, sparking an idea for her to create her own theories and consider experimenting with them.
Once finished, Mahiru sits at her desk and leans her head against her left hand. Glancing at her watch, she notices it is only 6:30 AM. Did she arrive too early? Sighing, she gets up and leaves the classroom.
Walking along the second-floor hallway, Mahiru glances out the window and is startled to see a monster. But when she blinks, it vanishes.
"Am I hallucinating? Is this from overexertion?" she wonders, shaking her head as she continues toward the school rooftop.
Reaching the rooftop, she enjoys the gentle breeze brushing against her skin, closing her eyes as she takes in the fresh air. Upon reopening them, she notices a giant bird flying high in the sky. Startled, she closes her eyes again.
Three seconds later, she opens them to find nothing but the beautiful blue sky.
"....." Mahiru mutters in frustration, unsure of what she saw. Should she visit a psychiatrist as a precaution?
Though uncertain, she calms herself and tries not to overthink the strange occurrence.
After spending ten minutes on the rooftop, enjoying the refreshing breeze, Mahiru heads back down to the second floor and walks toward her classroom.
While walking through the corridor, Mahiru senses an eerie atmosphere. Her vision turns red, the floor appears covered in blood, and the stench of death surrounds her.
At that moment, she feels a sharp headache. Unbeknownst to her, her crimson eyes change first to blue, then to black, and finally take on a triple-colored hue with an overlapping design. Within the pupils, a clock-like symbol ticks backward.
The countdown begins at 10, with each decrement intensifying her pain. When the countdown reaches 1, Mahiru, unable to bear the agony, loses consciousness. As her eyes close, they momentarily glow bright purple with an irregular circular pupil.
After collapsing in the corridor, Mahiru unknowingly transitions to another world while unconscious.
She now finds herself in a pristine white room adorned with intricate and beautiful carvings. In the center stands a tall statue of a woman with angelic wings, resembling a goddess.
"How remarkable. Your soul has endured dimensional distortion, allowing you to acquire extraordinary power," a foreign yet breathtakingly beautiful being speaks.
Hearing these words, Mahiru's soul vanishes from the ethereal place and returns to her body in the otherworldly realm.
