Chapter 19: THE HARDEST MISSION FOR A FORMER WAR MACHINE

Under the morning sun that was climbing higher, casting long shadows stretching across the schoolyard. The three-story building with cream paint and dark blue accents looked simple yet sturdy, like a small fortress protecting its inhabitants from a world that could sometimes feel too cruel. The spacious schoolyard was filled with shady trees providing cool spots in several corners, creating a calm and peaceful atmosphere. A small garden beside the building with old wooden benches was a favorite spot for students to sit and chat during break time, laughing together like they didn’t have a care in the world. But today, the atmosphere in Class IX-9 felt different. There was an unusual tension in the air, something that made everyone feel that something wasn’t right. Something that made hearts beat faster, something that made minds drift to places they couldn’t control.

Kai stood in front of the blackboard, white chalk in his tightly gripping hand, but his hand wasn’t moving. His fingers, usually firm and steady, now seemed stiff, like he was trying to hold back something he couldn’t contain. His eyes, usually sharp and alert, now stared blankly at the still-empty board, like he was searching for words he couldn’t find, like he was trying to remember something he’d long forgotten. He’d been standing there for almost five minutes without saying anything, without writing anything, just standing with an expression no one could read—an expression that made the girls in Class IX-9 exchange glances with growing concern.

"Hah..."

A soft sigh escaped Kai’s lips, barely audible like a whisper of wind in the night, but clear enough in the silent room. That long, heavy breath carried all the burdens he’d been carrying, all the exhaustion he’d never shared with anyone, all the worries he’d never expressed. He let out a long breath and lowered his chalk-holding hand, setting it on the desk with a tired motion—a motion that showed he was struggling with something bigger than himself.

"Mr. Kai?" Ella called from the front row, her voice careful and full of concern, like an older sister worried about her younger sibling. Her sharp eyes stared at Kai with undisguised curiosity, trying to read what was behind that tired expression. "Are you okay? You’ve looked really tired since earlier."

Kai looked at Ella, then scanned the room. Nine pairs of eyes stared at him with various expressions—some curious, some worried, some trying to understand what was happening behind the tired face he was showing. Mira, usually cheerful and full of energy, was now quiet, her usually sparkling eyes now dark with worry, her ever-present smile now gone. Rin, usually quick to speak and never hesitant to voice her opinions, just stared with raised eyebrows, her usually tapping hands now still. Even Eve had lifted her head from her laptop for the first time since class started, staring at Kai with an unreadable expression—an expression rarely seen on her usually flat face.

"Mr. Kai, what’s wrong?" Mira asked in a soft voice, trying not to pressure her teacher further. She leaned forward, her eyes full of genuine concern. "You look so tired. Like you’re carrying a heavy burden. Is there something you want to tell us?"

Kai sighed again, this time longer and heavier, like he was gathering the courage to say something difficult. He looked at the girls in front of him—nine girls whose fathers he’d killed eight years ago, nine girls who were the reason he chose to live, nine girls he had to protect from a cruel world. He wanted to say everything was fine, wanted to smile and continue the lesson as usual, wanted to pretend nothing was wrong. But the words felt too heavy to say, too heavy to fake.

"I... there’s something I need to tell you all," Kai said softly, his voice trembling slightly at the end, like he was trying to hold back emotions he couldn’t control. "About the sports competition."

"Sports competition?" Rin blinked, her eyebrows rising with growing curiosity. Her hands, which had been still, started tapping the desk again, as usual. "What’s that? I’ve never heard about this before."

"Every year, the school holds a sports competition to celebrate Phoenix Academy’s anniversary," Ella explained in a calm, knowledgeable voice, her eyes still fixed on Kai with full attention. "All classes are required to participate. It’s usually held at the end of the semester. But I’ve never heard about it from you before."

Kai nodded slowly, his hand reaching for the chalk again and starting to write something on the board—but his writing wasn’t clear, wasn’t neat like usual, like his mind was chaotic and unfocused. "I just found out today. The principal... Reina... told me this morning before duty started. And I have to prepare our class for the competition."

"That’s good, right?" Mira asked with a reassuring smile, a smile that still looked forced but tried to be genuine. Her eyes sparkled with a little enthusiasm starting to emerge. "We can play and have fun together. I like sports! I like running and moving around!"

"But there’s a problem," Kai continued, his voice growing softer, heavier, like he was admitting a weakness he’d never admitted before. "I... I don’t know what to do. I’ve never done this before. I’ve never been a teacher who has to prepare his students for a sports competition."

The room fell silent. The girls exchanged glances with different expressions—some surprised, some confused, some trying to understand what was really happening. Rin let out a long sigh, Mira looked down with a sad expression, and Ella stared at Kai with a deeper look—a look that showed she understood what her teacher was feeling, that she knew how hard it was to be someone who lacked confidence.

"Mr. Kai," Ella said in a calm voice, a voice trying to soothe. "You don’t need to worry. We can help. We’re used to doing everything ourselves."

"You?" Kai blinked, a little surprised by Ella’s offer. His eyes widened with curiosity starting to emerge.

"Yes," Ella answered firmly, her voice full of conviction. "We’re Class IX-9. We’ve been used to doing everything ourselves for a long time. We don’t need help from anyone. We’ve learned to survive on our own."

But as those words came out, the atmosphere in the classroom shifted. The girls’ faces started to change—from enthusiastic to gloomy, from optimistic to pessimistic, from confident to doubtful. Aria started biting her nails anxiously, a habit that always appeared when she felt insecure. Luna stared out the window with empty eyes, like she was searching for answers among the slow-moving clouds. Fay, who usually smiled, was now just silent, her usually empty eyes looking emptier than usual. Even Rin, usually spirited and full of energy, now looked down, not saying anything, her shoulders seeming to slump a little.

"But..." Iris broke the silence, her voice soft and full of doubt. Her eyes looked at her friends with an unreadable expression. "We’re the rebel kids. No one wants to be friends with us. No one wants to work with us. Even in sports competitions, we’re always... alone. We’re always the most hated team."

"Last year," Ella continued in a soft voice, her eyes looking down at the desk, not daring to look at anyone. "We signed up for the relay race. But no other class wanted to practice with us. They said we’d be a bad influence. They said we didn’t deserve it. We practiced alone on the empty field, and on competition day, we lost because no one wanted to be on our team. We ran alone on the empty track."

"The year before that," Nora added from the back row, her voice flat and emotionless, like she was telling something that had happened too many times. "We signed up for basketball. But the referee was unfair. He always gave us lower scores. Every time we scored, he said it didn’t count. Every time our opponents made a mistake, he ignored it. We lost badly, and everyone laughed."

"And the year before that," Aria continued in a trembling voice, her nail-biting fingers moving faster. "We couldn’t join any competition at all because no class wanted to accept us as a team. We just sat on the sidelines and watched. Everyone had fun, and we just... watched."

Kai heard all of this, and his chest felt tight like a heavy weight was pressing down on it. He looked at the girls in front of him—girls who were used to rejection, girls who were used to failure, girls who had lost hope. He saw their empty eyes, their slumped shoulders, and he felt something strange in his chest—something like anger, but also deep sadness. They’ve been hurt too many times, Kai thought. They’ve been betrayed too many times. They’ve lost faith in the world.

"You..." Kai paused for a moment, searching for the right words, words that could touch their wounded hearts. "You’re not alone. Not anymore."

All heads turned toward him. The girls stared at Kai with wide eyes, trying to understand what he was saying, trying to figure out if this was real or just a dream.

"I will protect you," Kai continued, his voice growing firmer, stronger, more full of conviction. "I will make sure you never feel alone again. I will fight for you. I will... I will be the teacher you need. The teacher who will never leave you."

"But, Mr. Kai—" Iris tried to cut in, but Kai had already raised his hand, stopping her mid-sentence.

"No buts," Kai cut in firmly, his eyes looking at each girl one by one. "I promise. I don’t care about your past. I don’t care about what others say. I don’t care about all the insults and rejections you’ve received. What I care about is you. And I will prove it."

The room fell silent. The girls stared at Kai with various expressions—some surprised, some disbelieving, some with tears starting to well up in their eyes. Mira smiled, this time with a genuine smile, one that wasn’t forced. Rin nodded slowly, her eyes sparkling with spirit starting to return. Ella looked down, hiding the tears starting to fall down her cheeks, tears she couldn’t hold back anymore. Luna stared at Kai with eyes that were no longer empty—there was something there, something like hope, something that made her look more alive than usual.

"We will join the sports competition," Kai said in a voice full of conviction, a voice that no longer trembled. "And we will win."

"But how?" Aria asked in a doubtful voice, her eyes still full of worry. "We’ve never won before. We always lose. We’re always last."

"Because this time you have me," Kai answered with a smile—a smile that for the first time looked genuine since this morning, a smile that made the girls feel something strange in their chests. "And I never lose. I won’t let you lose."

The girls exchanged glances, and slowly, smiles started to appear on their faces. Mira laughed softly, Rin smiled wide, and Ella nodded firmly. Fay, who had been silent, started smiling to herself, and Aria stopped biting her nails for the first time since class started.

"Alright," Ella said in a voice that was starting to grow firm, wiping the tears from her cheeks with the back of her hand. "Then we need to plan this carefully. What sports events will we join?"

"All of them," Ella answered quickly, her voice full of enthusiasm. "I want us to join every event there is. We need to show that Class IX-9 isn’t a cast-off class. We need to show that we can."

"But we can’t join all of them," Nora countered in a calm, logical voice, as usual. "We only have nine people. That’s not enough for all the sports events available. We need to choose wisely."

"Then what?" Rin asked in a frustrated tone, her hands clenched on the desk. "Do we pick the easiest ones? Take the shortcut?"

"No," Mira cut in with enthusiasm, her eyes sparkling with ideas starting to form in her head. "We pick the hardest ones. Let everyone see that we can. Let everyone know that Class IX-9 isn’t a class to be underestimated."

The girls started debating with passion. Their voices clashed, their ideas collided, and for the first time, the room felt alive—felt like a normal classroom, felt like a place where dreams could grow. Iris volunteered for the relay race, Rin wanted to play basketball, Nora wanted to do archery, Eve wanted to be a fair tech referee, Fay wanted to be an enthusiastic spectator, and Aria wanted to be the support team preparing drinks and food for everyone.

Kai watched them with a small smile on his face, a smile he couldn’t hide. He saw the spirit starting to appear in their eyes, hope starting to grow in their hearts, and he felt something strange in his chest—something like pride, but also deep gratitude. They haven’t given up, Kai thought. They’re still fighting. They still believe.

"Alright," Kai said in a firm voice, stopping the debate that was starting to heat up. "I’ll decide."

"What?!" Rin exclaimed in protest, her eyes widening with disbelief. "But we haven’t finished—we’re still debating—"

"I’ve been watching you," Kai cut in, his eyes moving from one girl to another, from one face to another. "I know each of your abilities. And I’ll place each of you in the event that suits you best."

"You’ve been watching us?" Mira asked with sparkling eyes, her smile growing wider.

"Since the first day," Kai answered honestly, without hesitation. "I always watch my students. That’s a teacher’s job."

Kai started walking between the desks, his steps slow and attentive, looking at each girl carefully. His hand pointed toward Rin, who was still sitting with her arms crossed, her expression still showing disbelief.

"Rin," Kai said firmly, his eyes looking at Rin with full conviction. "You’re joining basketball. I’ve seen how you move in class. Your reflexes are fast, and your body is athletic. You have a strong fighting instinct. You’re suited to be a main player."

Rin blinked, surprised by the choice. "But I’ve never—"

"You can," Kai cut in, his voice leaving no room for doubt. "I know you can. I’ve seen your potential."

Kai turned to Nora, who sat with her back straight in the back row, her pale blue eyes looking at Kai calmly. "Nora, you’re joining archery. I’ve seen how you sit so calmly and focused. You have incredible concentration. Archery requires calmness and focus. It suits you."

Nora just nodded slowly, but there was a small smile on her lips—a smile rarely seen, a smile that made her look younger and sweeter.

Kai turned to Mira, who sat with a wide smile, her eyes sparkling with enthusiasm she couldn’t hide. "Mira, you’re joining the relay race. I’ve seen how you move quickly and nimbly. Your legs are light and your energy is abundant. You’re suited for running."

"Wow, really?!" Mira exclaimed enthusiastically, her hands clenched in front of her chest. "Mira loves running! Mira will be the fastest runner!"

Kai turned to Iris, who sat with a mysterious smile, her eyes glinting with intelligence she didn’t hide. "Iris, you’re also joining the relay race. I’ve seen how you walk with light steps. You’re fast and agile. You’ll be a good runner."

"Of course, Sir," Iris answered with a satisfied smile. "I’ll prove that I can."

Kai turned to Ella, who sat calmly in the front row, her sharp eyes looking at Kai with full attention. "Ella, you’re joining volleyball. I’ve seen how you manage the class so well. You have strong leadership instincts. In volleyball, you can be the team captain."

Ella nodded firmly, her eyes sparkling with spirit starting to emerge. "Alright, Sir. I’ll take responsibility."

Kai turned to Eve, who was still staring at her laptop, her fingers still dancing across the keyboard. "Eve, you’re joining chess. I’ve seen how you think quickly and logically. You have a genius brain. Chess is a sport of the mind."

Eve lifted her head, a little surprised by the choice. "I’m joining chess? But I’ve never—"

"You can," Kai cut in, his voice full of conviction. "I believe in you."

Kai turned to Luna, who sat in the corner of the room with half-closed eyes, her silver-gray hair hanging over her shoulders. "Luna, you’re joining archery with Nora. I’ve seen how you observe so carefully. You have sharp vision. In archery, vision is everything."

Luna stared at Kai with eyes that were no longer empty. There was something there—something like warmth, but also deep gratitude. "Alright, Sir."

Kai turned to Aria, who sat with an anxious expression, her fingers still biting her nails nervously. "Aria, you’re joining the support team. I’ve seen how you always prepare everything well. You’ll be the one providing drinks and food for our team."

"M-me?" Aria blinked, a little relieved but also a little disappointed. "I’m not competing?"

"Not everyone has to compete," Kai said gently, his voice full of understanding. "The support team is also important. Without you, the players wouldn’t have the energy to compete. You’re the backbone of the team."

Kai turned to Fay, who sat with an empty smile in the corner of the room, her gaze drifting off in an unclear direction. "Fay, you’re joining as an enthusiastic spectator. I’ve seen how you always smile for no reason. Your spirit will rub off on the players."

Fay blinked, then laughed softly. "I like that! I’ll cheer for all of you!"

The girls exchanged glances with different expressions. Some were surprised, some happy, some still in disbelief. But all of them felt the same thing—they felt valued, they felt noticed, they felt that someone genuinely cared about them for the first time in a long while.

"Mr. Kai," Ella said in a voice that was starting to calm, her eyes looking at Kai with full respect. "You really have been watching us."

"Since the first day," Kai answered honestly, without hesitation. "I always watch my students. That’s a teacher’s job."

"But how do you know all that?" Rin asked with curiosity, her eyes narrowing. "We’ve never shown our abilities. We’ve never practiced in front of you."

"You always show your abilities," Kai answered. "In the way you move, in the way you talk, in the way you interact with each other. I just need to pay attention. And I always pay attention."

The room fell silent. The girls stared at Kai with various expressions—some surprised, some touched, some with tears starting to well up in their eyes. They’d never felt so noticed before. They’d never felt so valued before.

"Alright," Ella said in a voice that was starting to grow firm, wiping the tears from her cheeks. "Then we need to start training right away. The competition is in two weeks. We don’t have much time."

"I’ll make a training schedule," Kai quickly added, his hand reaching for a notebook from the desk. "We’ll practice every day after school. I’ll make sure you’re ready."

"But, Mr. Kai," Aria cut in with a doubtful voice, her fingers starting to bite her nails again. "Are you sure we can win? We’ve never—"

"I’m sure," Kai cut in firmly, his eyes looking at Aria gently but surely. "I never doubt my students."

"But—"

"No buts." Kai stared at Aria with a gentle but firm gaze, a gaze that said he believed in her, that he wouldn’t give up, that he would always be there for them. "I will protect you. I will make sure you win. And I will make sure you never feel alone again."

Aria fell silent. Tears started flowing down her cheeks—tears she couldn’t hold back anymore, tears she’d been holding in for a long time. She looked down, hiding her wet face.

"I... I’ve never felt like this before," Aria whispered in a trembling voice, a voice barely audible. "I’ve never felt... noticed."

"Because now you have me," Kai said in a soft voice, a voice full of warmth and certainty. "And I will never leave you."

All the girls in Class IX-9 stared at Kai with wet eyes. They didn’t say anything, but their words didn’t need to be spoken. Their expressions were enough—expressions that showed they believed in him, that they respected him, that they would fight with him.

"Alright," Ella said in a voice that was starting to grow firm, wiping the tears from her cheeks with the back of her hand. "We start training tomorrow. I’ll arrange the schedule."

"I’ll prepare the equipment," Mira added enthusiastically, her eyes sparkling with excitement. "I can borrow basketballs from the sports storage. I know the storage keeper."

"I’ll find out the competition rules," Eve added without lifting her head from her laptop, her fingers starting to dance across the keyboard again. "I’ll make an analysis of our team’s strengths and weaknesses. I’ll make a strategy."

"I’ll practice archery every day," Nora said in a calm voice, her eyes looking at Kai with full determination. "I’ll make sure I don’t let the team down."

"Me too," Luna added softly, nodding slightly. "I’ll practice with Nora."

"I’ll run every morning," Iris said with a confident smile. "I’ll be the fastest runner. I’ll make sure our team wins."

"I’ll keep our spirits up," Fay added with a wide smile, her eyes sparkling with joy. "I’ll cheer for all of you! I’ll make chants!"

"And I’ll prepare drinks and food," Aria said with a smile starting to appear, her eyes no longer anxious. "I’ll make sure none of you get thirsty."

"And me," Rin added with enthusiasm, her fist clenched on the desk. "I’ll be the best basketball player ever! I’ll lead our team to victory!"

Kai watched them with a smile on his face, a smile he couldn’t hide. He saw the spirit starting to appear in their eyes, hope starting to grow in their hearts, and he felt something strange in his chest—something like pride, but also deep gratitude. They haven’t given up, Kai thought. They’re still fighting. They still believe. And I’ll be by their side, no matter what.

"Alright," Kai said in a voice full of conviction, his eyes looking at each girl one by one. "We will win. I promise."

Maybe, Kai thought, I can be a good teacher. Maybe I can protect them. Maybe I can... be someone worthy of respect.

And for the first time in a long while, he felt hope growing in his heart—hope that made him believe everything would be okay.
