The blue sea stretched out endlessly, reflecting the scorching yet exhilarating summer sun. In the midst of that azure expanse, an iron giant cleaved through the waves with the elegance of royalty.
The luxury cruise ship, Speranza.
To the first-year students of Advanced Nurturing High School, this ship was the very definition of an earthly paradise. It boasted a massive open deck, a crystal-clear swimming pool, a five-star restaurant serving cuisine from around the globe, and even a private cinema and bar.
"THIS IS INSANE! ABSOLUTELY INSANE!"
Ike Kanji's scream echoed across the pool deck, nearly drowning out the sound of the crashing waves. He, Yamauchi, and Sudou were running around the edge of the pool in tacky swim trunks, completely forgetting the trauma of the midterm exams they had just barely survived.
"Look at that! Kushida-chan in a bikini!" Yamauchi pointed with a trembling finger, practically drooling.
Indeed, Kushida Kikyo was lounging on a deck chair, wearing a swimsuit that accentuated her assets.
In another corner, Karuizawa Kei was leading a group of Class C girls (who now felt like royalty thanks to their high class points), laughing crisply as she applied her newly purchased, expensive sunscreen.
"They look happy," Horikita Suzune commented. She stood on the balcony of the upper deck, wearing a simple yet elegant summer dress, observing the chaos below with an analytical gaze.
"Let them recharge their energy," Seiji Koroizumi replied, standing right beside her. He was wearing a sunflower-patterned Hawaiian shirt that somehow perfectly suited his laid-back aura.
"The human brain requires a dopamine release after a period of high cortisol stress. If you forbid them from playing now, they'll explode when the real exam begins."
Suzune glanced at Seiji. "You speak as if you're certain there will be an exam."
"This ship is named Speranza, which means Hope," Seiji took a sip of his mango juice. "In the myth of Pandora, hope was the only thing left after all the disasters had escaped the box. Rather an ironic name for a school vacation, wouldn't you say?"
Seiji finished his drink in one gulp.
"Well, I've had enough of the sun. My sensitive skin requires protection."
"Where are you going? Not going for a swim?"
"I much prefer diving into a sea of words rather than a sea of saltwater," Seiji answered, adjusting the collar of his shirt. "I've heard this ship's library houses a collection of rare European literature. I'll see you later, Horikita. Don't forget to have some fun; that's an order from your teacher—I mean, friend."
Seiji waved casually, leaving behind Suzune, who let out a soft scoff but smiled faintly as she watched the young man's retreating back.
.......................................................................................….
The Speranza's library was located on Deck C, far removed from the hustle and bustle of the pool and restaurants. The room was designed with dark mahogany interiors, thick carpets that muffled the sound of footsteps, and the soothing scent of old paper.
As Seiji stepped inside, the silence welcomed him like the embrace of an old friend.
However, he was not alone.
At a table near a porthole window overlooking the sea, sat a girl with long silver hair that shimmered under the sunlight.
Shiina Hiyori.
The girl was completely immersed in a thick book, entirely isolated from the outside world.
Seiji smiled. He approached soundlessly—an assassination footwork technique that had become a mere reflex—and took a seat across from Hiyori.
Hiyori wasn't startled. She simply lifted her eyes slightly, saw Seiji, and offered a gentle smile. A pure smile, untainted by inter-class politics.
"You came, Koroizumi-kun," she whispered.
"You invited me through bookworm telepathy, Shiina-san," Seiji joked softly. "What are you reading today?"
"The Old Man and the Sea," Hiyori held up the Ernest Hemingway book. "It suits this oceanic atmosphere perfectly, don't you think? An old man's struggle against a giant marlin, loneliness, and dignity."
"A rather melancholic choice," Seiji commented. "I myself planned on reading a modern annotated edition of The Art of War. Mental preparation."
"Fufufu. You're always on guard, aren't you?"
They didn't speak much after that. Both opened their respective books, allowing the silence to fill the space between them.
An hour passed. Two hours.
To anyone else, sitting in silence for two hours might be pure torture. But to Seiji and Hiyori, this was the highest form of communication. They shared space, shared time, and shared peace without needing to pollute the air with empty small talk.
However, that peace was eventually disrupted.
Tak. Tak. Tak.
The rhythmic sound of a hard object tapping against the wooden floor approached. It wasn't the sound of shoes, but the sound of a cane.
Seiji didn't look up from his book, but his ears twitched. He recognized that rhythm. The rhythm of a limping, yet utterly authoritative stride.
The library doors opened.
Two figures entered. One was a sour-faced girl with short purple hair, Kamuro Masumi, who carried a flat wooden box in her hands.
And leading the way was a petite girl with short silver hair, wearing a white dress and a beret that made her look like a living porcelain doll.
Sakayanagi Arisu.
By all rights, given her congenital heart condition, Sakayanagi shouldn't have been allowed to participate in long trips or strenuous physical activities like this island vacation. The school usually kept her back on campus.
However, the Queen of Class A (now Class B) had an agenda of her own.
Sakayanagi's eyes swept across the quiet library, eventually locking onto Seiji and Hiyori's table. The smile on her lips widened, sweet yet venomous.
"Ara, ara," Sakayanagi's voice shattered the library's sacred silence. "I was wondering where the 'King of Class C' was hiding from the scorching sun. Turns out you're on a date with a princess from an enemy class?"
Hiyori looked up, slightly annoyed but maintaining her politeness. "Good afternoon, Sakayanagi-san. We are merely reading."
Seiji closed his book slowly. He turned his body to face Sakayanagi.
"Good afternoon, Sakayanagi-san," Seiji greeted amiably. "I'm surprised to see you here. I heard your health wouldn't permit a sea voyage."
"Fufufu, my doctors did advise against it," Sakayanagi stepped closer, her cane clicking with every step she took.
"But, how could I simply sit quietly in the dorms while such a fascinating 'toy' roams free on the open sea? My curiosity overruled my medical recommendations, Koroizumi-kun."
Sakayanagi stopped right at the edge of Seiji's table. She stared at the young man with an intensity that sent shivers down Kamuro's spine.
"A perfect 500 score. Transforming a trash class into a primary contender. And extorting upperclassmen with a smile," Sakayanagi listed Seiji's sins—or rather, his achievements. "You are an anomaly, Koroizumi-kun. And I despise anomalies that I haven't tested myself."
She gestured to Kamuro.
Kamuro let out a rough sigh, then placed the wooden box she was carrying onto the table, right between Seiji and Hiyori.
It was a folding chessboard made of ebony and ivory.
"Chess?" Seiji asked, raising an eyebrow.
"I hear you have a fondness for strategy," Sakayanagi said. "Let us kill some time before dinner. One game. I want to see what goes on inside your head, Koroizumi Seiji."
Hiyori looked at Seiji, slightly worried. "Koroizumi-kun..."
Seiji offered Hiyori a reassuring smile, then turned his gaze back to Sakayanagi. His eyes changed. The warmth of "Koro-sensei" receded slightly, replaced by the calculative sharpness of "The Reaper".
"An intriguing offer," Seiji said. "As it happens, in the past, chess was how I trained my patience. I accept your challenge."
Sakayanagi sat in the chair Kamuro pulled out for her. She opened the chessboard. The pieces were beautifully carved, heavy, and solid.
"Please, make your choice," Sakayanagi said, gesturing to both sides of the board.
In chess, the player controlling the White pieces has the First Move Advantage. Statistics show that White has a winning probability of around 52-56% at the tournament level.
Without hesitation, Seiji spun the board around.
He placed the row of Black pieces in front of him.
"I'll take Black," Seiji stated casually.
Sakayanagi's eyes narrowed. "You're handing the initiative over to me? That's arrogant, Koroizumi-kun. Or are you underestimating me because I'm crippled?"
"Not at all," Seiji replied. He arranged his King and Queen pieces with precision. "It's precisely because I respect you. A challenger must always allow the Queen to make the first move, right?"
"Heh," Sakayanagi chuckled softly, but her eyes were ice cold. "Very well. If you wish to die quicker, I shall grant you your wish."
The game began.
Move 1: White (Sakayanagi) — Pawn to e4. A King's Pawn Opening. Aggressive, controlling the center. Standard, yet lethal in the hands of an expert.
Move 1: Black (Seiji) — Pawn to e5. A classic response. Seiji accepted the open game.
The game proceeded at breakneck speed for the first ten moves. Blitz. Neither player hesitated; their hands moved as if they had memorized thousands of opening variations.
Kamuro Masumi, standing behind Sakayanagi, could only frown. She knew the basic rules of chess, but what was happening on that board was entirely beyond her comprehension. The pieces moved in a confusing, violent harmony.
However, Shiina Hiyori saw something else.
As a mystery lover, Hiyori was accustomed to seeing patterns and narratives. She viewed the chessboard not as a game, but as a story.
Sakayanagi-san plays like a tyrant, Hiyori analyzed internally.
Sakayanagi's playstyle was aggressive and oppressive. She sacrificed pawns without a second thought to open up lanes for her major pieces. Her White Knights and Bishops charged into Seiji's defenses, creating a suffocating pressure.
While Koroizumi-kun...
Seiji was playing... weirdly.
He was using the Black pieces—the defensive position—but he wasn't building a fortress. His pieces were scattered. His Knights jumped to seemingly unstrategic positions on the edges of the board. His Queen retreated instead of attacking.
To the untrained eye, Seiji was being cornered.
"You're playing awfully passively," Sakayanagi commented as she advanced her Bishop, threatening Seiji's King. "Is this a reflection of your strategy in class?"
"Defending does not mean standing still, Sakayanagi-san," Seiji countered calmly. He slid his Rook over one square. "Sometimes, you have to let your opponent walk into the spider's web before you bite."
"A spider's web?" Sakayanagi scoffed. "I will burn it to the ground."
Move 24: White — Queen captures Black Knight on f6. "Check," Sakayanagi declared.
It was a devastating strike.
Seiji's defense was blown wide open. The Black King was exposed.
Hiyori held her breath. "Koroizumi-kun..."
But Seiji... he smiled.
It wasn't a smile of despair. It was his signature Nurufufufu smile, the smile of a creature with a thousand tentacles who had once seen the world at Mach 20 speed.
"You know, Sakayanagi-san," Seiji said softly, his hand hovering over the board. "In the world of chess, statistics say Black only has a 25-30% chance of winning."
"And you are about to become a part of that statistic," Sakayanagi cut in.
"Perhaps," Seiji moved a single, small Pawn forward one square. A seemingly insignificant move.
"But you're forgetting one thing about the Black pieces. Because they move second, they possess the ability to adapt to White's strategy. They don't start the war; they end it."
Suddenly, the atmosphere of the game shifted.
Sakayanagi frowned. She looked at the pawn's move. Then she looked at the position of Seiji's Bishop on the left flank. Then the position of the Rook on the back rank.
Her eyes widened.
That trap... it wasn't set five moves ago. It had been prepared since the seventh move, when Seiji moved his Knight to the edge of the board—a move Sakayanagi had deemed a blunder.
Those scattered Black pieces weren't disorganized. They were tentacles.
Every piece was connected to one another in a flexible web of defense. When Sakayanagi captured the Knight on f6, she had walked straight into a Killing Zone.
"Impossible..." Sakayanagi whispered.
If she retreated her Queen, Seiji's Bishop would capture her Rook. If she held her ground, Seiji's Pawn would promote.
Sakayanagi's entire aggressive assault had suddenly been inverted into a prison for her own King.
"How..." Sakayanagi stared at Seiji. "You lured me here? From the very beginning?"
"You were too focused on destroying my King," Seiji explained gently, his tone like that of a teacher correcting a student's careless mistake. "You sacrificed your pawns for the sake of the attack. You forgot that a King's strength lies in the people who protect him."
Seiji pointed to his intact Black pieces.
"My class... my pieces... I didn't throw them away. I placed them in positions where they could protect each other. And now..."
Seiji moved his Black Bishop.
Move 28: Black — Bishop to h3.
"Checkmate."
Silence descended upon the table, heavy and absolute.
Sakayanagi's White King was surrounded. There was no escape route. Her path was blocked by her own pieces, jammed together due to her failed aggressive assault.
Sakayanagi Arisu sat frozen.
The hand gripping her cane trembled slightly. Not out of anger, but from a sensation she hadn't felt in a very long time.
Defeat.
And it wasn't just a defeat due to a blunder. This was a total strategic defeat. She had been read, herded, and executed perfectly by someone playing the underdog pieces.
Kamuro Masumi's jaw dropped. She didn't understand the details, but she knew her boss had just been annihilated. "Sakayanagi Arisu... lost?"
Shiina Hiyori let out a breath she hadn't realized she was holding. Her eyes sparkled with awe. She had watched the "story" on the board end with a brilliant plot twist.
The tyrant was defeated not by a sword-wielding hero, but by a guerrilla strategy that united the weak.
Seiji began gathering his pieces back into the box.
"Good game, Sakayanagi-san," Seiji said sincerely. "Your aggressiveness was terrifying. Had I let my guard down for even a second on move 15, I would have undoubtedly been crushed."
Sakayanagi stared at the empty board, then looked up at Seiji. Slowly, the smirk returned to her face, this time wider and more genuine than before.
"Hahahaha!" Sakayanagi laughed. "Magnificent. Truly magnificent, Koroizumi-kun!"
She stared at Seiji with sparkling eyes, like a child who had just found a new, unbreakable toy.
"My father was right. This cohort... is truly a jewelry box. And you are the black diamond within it."
Sakayanagi stood up, leaning heavily on her cane.
"You win today. But remember, on that island... the game isn't chess. Human pieces aren't always as obedient as carved wood. I want to see if you can protect your 'people' in the wild."
"Of course," Seiji stood up, offering a slight, gentlemanly bow. "Protecting students is a teacher's duty. I'll see you on the island, Queen."
Sakayanagi turned around and walked out of the library, followed by a still-bewildered Kamuro. The sound of her cane gradually faded away.
After the door closed, Hiyori looked at Seiji.
"You're terrifying, Koroizumi-kun," Hiyori said, though with a smile.
"I just got lucky," Seiji deflected. "Black wins 30% of the time, right? Today was my lucky day."
"No," Hiyori shook her head. "That wasn't luck. You played like... you were trying to teach her something."
Seiji didn't answer; he only offered a mysterious smile. He picked his book back up.
