REBIRTH FROM MY PAST

School life ;Tragic
Chapter 2- FIRST BLOOD ON PE
The next morning Ren showed up 20 minutes early.
Not because he was responsible. Because he was scared.
If Kaito wanted to kill him, he’d do it where there were no witnesses.
The empty classroom was quiet. Too quiet.
Third row, window seat. Still there.
The seat behind him was empty too. For now.
First period was math. Ren copied equations he didn’t understand and tried not to look at the reflection in the window.
His own face kept flickering. Scar. Armor. 19-year-old eyes that had seen too much.
Second period: PE.
“Alright, change and meet me at the field in 5!” Coach Hayashi yelled.
Takumi threw Ren his jersey. “Dude you look pale. You sure you’re not still concussed?”
“I’m fine,” Ren muttered.
He wasn’t.
The field was hot. August in San Jose del Monte was no joke. But the cold followed him.
Because Kaito was already there, stretching, shirtless.
Of course he was.
Kaito looked up as Ren walked in. His eyes did that thing again — 800 years in one second.
Then he smiled. “General. Try not to die today. It’d be embarrassing if you did it twice.”
They were doing sparring drills. Wooden swords.
Coach paired them randomly. Or at least, Ren hoped it was random.
“Kaito and Ren. Center court.”
The entire class went quiet. Everyone remembered the transfer with the killer eyes.
Ren picked up the shinai. It felt wrong. Too light. In his past life his sword was 3 kilos of steel. This felt like a toy.
“Begin!”
Kaito moved first.
Not like a student. Like a soldier.
The wooden sword came in fast, aimed for Ren’s shoulder.
Instinct took over.
Ren sidestepped. Too fast. Humanly too fast.
The air rippled. For a second, his vision went red. Snow. Armor.
_“Block.”_ The voice in his head.
Ren’s shinai came up and met Kaito’s with a crack that echoed.
Kaito’s eyes widened a fraction. Then he grinned.
“There you are.”
They traded blows.
To everyone else it looked like a normal PE match.
To them, it was the battlefield again.
Kaito pressed forward, driving Ren back. “You remember the stance. But do you remember why you dropped it?”
“I remember you being an idiot who couldn’t see the bigger picture,” Ren snapped.
That was a mistake.
Kaito’s next strike wasn’t practice. It was aimed to hurt.
Ren saw it coming a second too late.
The voice screamed: _“MOVE!”_
Something hot surged in Ren’s chest.
The world slowed.
His hand moved on its own, and the shinai in his grip glowed faint blue.
He brought it up.
BOOM.
The impact sent both of them skidding back. Dust kicked up.
Kaito stumbled. Ren fell to one knee, gasping.
The glow was gone.
But the wooden floor under Ren’s feet had a crack in it. A crack shaped like a blade.
Silence.
35 students staring.
Coach Hayashi running over. “What the hell was that?!”
Ren looked at his hands. They were shaking.
Kaito stood up slowly, brushing dirt off. He looked at Ren, then at the crack, then back at Ren.
And he laughed.
Quiet at first. Then louder.
“Good. You’re not dead yet.”
He turned to Coach. “My bad, sensei. Got too into it. Must’ve hit the ground weird.”
Coach was not buying it. But without proof, what could he do?
“Both of you. Office. Now.”
As they walked off the field, Kaito leaned close to Ren.
“Powers are back,” he whispered. “Which means the others will feel it too. You’ve got about a week before they come for you.”
“Why are you helping me?” Ren hissed back.
“I’m not,” Kaito said. “I’m testing you. If you’re weak, I’ll be the one to end you. Properly this time.”
__
The detention room smelled like old erasers and bad decisions.
Coach Hayashi sat behind the desk with his arms crossed. “I don’t know what I saw out there, and I don’t want to know. But if either of you breaks school property again, you’re both benched for the tournament.”
Kaito nodded like the perfect student. “Yes, sensei. We got carried away.”
Ren just stared at his hands. The faint blue glow was gone, but his palms still tingled.
“Clean the gym storage after school. Both of you. Together.” Coach sighed. “Get out.”
The door closed behind them.
Immediately, Kaito’s mask dropped.
“You idiot,” he hissed. “Do you have any idea what you just did?”
“What, glow a little? You’re the one who tried to take my head off.”
“That wasn’t me trying to kill you,” Kaito said. “That was me seeing if you’d die like last time.”
Ren stopped walking. “Say that again.”
“You heard me.” Kaito turned, eyes cold. “800 years ago you threw your life away to ‘end the war.’ You died. I watched you die. And now you’re back with half your memories and zero control. If you can’t fight, the others will tear you apart.”
“The others.”
“The generals,” Kaito said. “There were five of us. You, me, and three more. We all died in that snow. And we’re all waking up.”
Before Ren could answer, the lights in the hallway flickered.
Once. Twice.
At the far end, by the stairwell, a girl was standing.
School uniform. Long black hair. She wasn’t from their class.
She was looking directly at Ren.
And smiling.
Then the lights went normal, and she was gone.
Kaito saw it too. His jaw tightened. “That was fast.”
“Who was that?” Ren asked.
“Yumi,” Kaito said. “The strategist. She was the first one to die after you. And she never forgave you for it.”
The bell rang for last period.
*Gym Storage. 4:30 PM.*
Dust. Broken volleyballs. And silence.
Ren was stacking mats when it happened.
The air got cold again. His breath fogged.
On the wall, written in frost that wasn’t there a second ago:
_YOU LIED TO US_
“Kaito,” Ren said quietly.
“I see it,” Kaito answered, already with a wooden sword in hand. From where? The storage didn’t have those. “Don’t look her in the eyes.”
The door slammed shut by itself.
Yumi stepped out from behind the shelves. Same uniform. But her shadow was wrong. It was wearing old robes. Holding a fan made of bone.
“Hello, General,” she said sweetly. “It’s been a while.”
“Yumi. Don’t,” Kaito warned.
“Oh, I’m not here for you, Kaito.” She tilted her head at Ren. “I’m here for the traitor.”
She moved.
Not walking. Gliding.
The fan snapped open and a wave of cold cut across the room.
Ren ducked. The ice sliced the mat behind him in half.
His heart was pounding. The voice in his head was screaming.
_“FIGHT OR DIE!”_
Without thinking, Ren grabbed a broom handle. It felt right in his hand.
He remembered this. Not a broom. A spear.
The blue glow came back. Faint, running along the wood.
Yumi paused. “Oh? You do remember.”
She attacked again.
Ren blocked. Once. Twice.
Each hit sent frost across the floor.
Kaito was circling, not interfering. Testing.
Ren was losing. His body wasn’t used to this.
Yumi’s fan came for his throat.
Instinct. Memory. Rage.
Ren stepped in instead of back and drove the broom handle forward.
The blue light flared.
The handle didn’t hit Yumi.
It hit the air in front of her and the air _shattered_.
Like glass.
Yumi was thrown back into the shelves. She landed on her feet, laughing.
“Good! You’re angry!” Blood dripped from her lip. “I was so bored without you, Ren.”
She looked at Kaito. “He’s still broken. But he’s ours again.”
Then she was gone. Just frost and a cold draft.
Silence.
Ren dropped the broom. His hands were bleeding from splinters. The glow faded.
“What the hell was that?” he breathed.
“That,” Kaito said, “was her holding back. If she’d been serious, you’d be dead.”
He walked over and offered Ren his hand.
Ren didn’t take it.
“Why didn’t you help?”
“Because you needed to remember how to stand on your own,” Kaito said. “The war is starting again, Ren. And this time, you’re the target.”
Outside, the sky had turned red. Not sunset red.
War red.
___
The walk home felt longer than 800 years.
San Jose del Monte was loud. Tricycles. Karaoke from a sari-sari store. Kids playing tumbang preso.
Normal. All of it was normal.
Except Ren couldn’t stop seeing the past layered over it.
That convenience store? It was a supply tent.
That overpass? An archer’s nest.
That old man selling fishballs? He had Yumi’s eyes for half a second.
“You’re spacing out,” Kaito said. He was walking beside Ren like this was casual. Like they weren’t both covered in invisible blood.
“Your fault,” Ren muttered. “You and your ghost girlfriend with the ice fan.”
“She’s not my girlfriend,” Kaito said dryly. “She tried to kill me twice. We have a very healthy relationship.”
Ren almost laughed. Almost.
His phone buzzed.
Unknown Number: `The snow remembers you. Meet me at the old shrine. Come alone. -R`
Ren stopped walking.
“What?” Kaito asked.
“Did you send this?” Ren showed him the phone.
Kaito went still. “I don’t have your number. And I don’t text. Too modern.”
“Then who’s R?”
“There is no R,” Kaito said. “Not among the five.”
“Five generals. You, me, Yumi... who else?”
“Hayato. The berserker. And Sora. The healer.” Kaito’s voice dropped. “If this is from one of them, it’s a trap.”
Another buzz.
Unknown Number: `You’re running out of time, Ren. They’re already looking for you.`
The screen glitched. For a second the text wasn’t words. It was old script. Battlefield orders.
Ren pocketed the phone. “I’m not going.”
“You have to,” Kaito said. “If we don’t find out who R is first, Yumi or Hayato will.”
They reached the split in the road. Ren’s house was left. The shrine was right.
Kaito didn’t follow.
“This is where I leave you,” he said. “If I go, they’ll know I’m helping you. And I’m not. Not yet.”
“Coward,” Ren said.
“Smart,” Kaito corrected. “Don’t die. Again.”
He walked away, hands in pockets.
*7:12 PM. The Old Shrine.*
It was abandoned. Moss on the torii. Offerings rotted away.
Ren shouldn’t have come.
He came anyway.
The air was heavy. Like before a storm.
“Hello?” His voice echoed.
No answer.
Just wind. And the sound of wood creaking.
Then footsteps behind him.
Ren turned.
It wasn’t Yumi. It wasn’t Kaito.
It was a boy in his school uniform. About 16. Messy brown hair. Glasses. Looked like he’d never thrown a punch in his life.
He was holding a phone.
“Ren Tachibana?” the boy asked, pushing up his glasses.
“Who are you?”
“R,” the boy said simply. “And you’re late.”
Ren’s instincts screamed. This kid wasn’t a threat.
Which meant he was the biggest threat.
“You texted me,” Ren said.
“I did.” R smiled. It didn’t reach his eyes. “Do you know why you were reborn, Ren?”
“To finish something.”
“Wrong.” R tilted his head. “You were reborn to be judged.”
The air shifted.
Behind R, the shadows moved. They pulled together and formed a shape.
Tall. Armor. A massive nodachi over its shoulder.
But the face... the face was blank. No eyes. No mouth.
Hayato.
“He doesn’t remember how to speak yet,” R said casually. “But he remembers how to kill. Especially you.”
Hayato took one step forward. The ground cracked.
Ren’s heart dropped into his stomach. The blue glow flickered in his hands but it was weak. Shaky.
He wasn’t ready.
_“RUN,”_ the voice in his head said.
_“FIGHT,”_ another voice said. Older. Colder. His own voice from the past.
R watched him, curious. “Which one will you listen to, General?”
Hayato raised the nodachi.
And Ren moved.
He didn’t think. He grabbed a loose roof tile and threw it.
Not at Hayato. At the shrine bell above.
CLANG.
The sound was deafening.
Hayato flinched. The shadow flickered.
That was all Ren needed.
He bolted.
Through the torii. Down the steps. Into the street.
Behind him he could hear R laughing. Soft.
“Run, Ren! Let’s see how far you get!”
He didn’t stop running until he was back on a main road, surrounded by people, lights, noise.
Safe.
His phone buzzed again.
Unknown Number: `Good. You chose to run. The coward I knew.
See you in homeroom tomorrow. -R`
Ren leaned against a wall, breathing hard.
His hands were shaking. But not from fear.
From anger.
Because deep down, in that snow-filled memory,
he remembered Hayato.
And he remembered why Hayato had no face.
Ren didn’t sleep.
He sat by his window all night, watching the street. Every shadow was Hayato. Every car headlight was Yumi’s fan.
His phone stayed dark after that last text.
`See you in homeroom tomorrow.`
Great.
*7:45 AM. Classroom 2-A.*
He was in his seat early. Again.
The room filled up slowly. Takumi came in yawning, threw his bag down. “Bro you look like hell. Did you get jumped last night?”
“Something like that,” Ren said.
The door slid open.
Kaito.
He looked Ren over once. Saw the dark circles. Saw the tension in his shoulders.
He said nothing. Just sat behind him.
The temperature dropped 2 degrees.
“Morning, General,” Kaito murmured. “You reek of fear. And shrine dust.”
“How do you know about that?”
“I know everything that happens to you,” Kaito said. “Whether I want to or not.”
First period: Japanese Literature.
Ms. Akiyama was talking about classical poems. About war. About loss.
Ren tried to take notes.
The kanji on the board started to blur.
And then it wasn’t kanji anymore.
It was a battlefield report.
`Casualties: 4,000. Morale: Low. General Ren missing.`
His hand started writing on its own.
Not in his notebook. In the margins. In old script.
`I’m sorry. I’m sorry. I’m sorry.`
“Ren?”
Ms. Akiyama’s voice snapped him back.
The board was normal. His notebook was normal.
But his hand was cramping, and there was ink all over his fingers.
“Are you alright?” she asked.
“Yeah,” Ren lied. “Just... tired.”
Kaito kicked the back of his chair. Once.
A signal. _Get it together._
Second period: History.
The topic was the Sengoku period.
The teacher put up a map.
Ren recognized every castle. Every route.
Because he’d burned three of them.
His vision tunneled.
Snow. Screaming. The smell of iron.
He was 19 again, standing over a map, pointing.
“Flank them here. Burn the fields. Don’t leave survivors.”
“Ren Tachibana.”
He jolted. The classroom was back. 35 kids staring.
“Stand up,” the teacher said.
Ren stood.
“What year did the Battle of Kawanakajima take place?”
He didn’t know. This life’s Ren didn’t know.
But the other Ren did.
“1561,” he said without thinking. “And it didn’t matter. Because we lost the war anyway.”
Silence.
“...That’s correct,” the teacher said slowly. “But that last part wasn’t in the textbook.”
Kaito raised his hand. “Sensei, Ren was in a car accident last week. Head trauma. He sometimes says weird stuff.”
The teacher frowned but nodded. “Sit down, Tachibana. Go to the nurse if you feel dizzy.”
Ren sat. His legs were shaking.
Kaito leaned forward. “You need to learn to control it. Or they’ll find you before you’re ready.”
“I don’t know how,” Ren whispered.
“You will,” Kaito said. “Or I’ll kill you myself. Again.”
*Lunch. Nurse’s Office.*
Ren went because he had to. Not because he wanted to.
The nurse’s office was clean. White. Smelled like antiseptic.
The nurse herself was new.
She couldn’t have been older than 25. Short hair. Soft eyes. A small mole under her left eye.
She looked up from her clipboard and smiled.
“Ren Tachibana? Head trauma follow-up?”
“Yes,” Ren said.
She walked around the desk.
And Ren felt it.
That same cold. That same _wrong_ feeling he got from Kaito and Yumi.
But different. Warmer.
“Let me see your eyes,” she said.
Her fingers were gentle as she lifted his eyelids.
For a second, her eyes weren’t brown.
They were gold. Like sunlight through leaves.
Sora.
The healer.
She let go and stepped back. “You’re fine. Physically.”
“Then why do I feel like I’m losing my mind?” Ren asked.
“Because you are,” Sora said quietly. So only he could hear. “Two lives in one head will do that.”
Ren stared. “You remember too?”
“I never forgot,” she said. She poured him tea. “You saved me, remember? In the last life. You pulled me out of the fire.”
Ren didn’t remember. But something in his chest hurt like he did.
“Don’t trust R,” Sora whispered. “He’s not one of us. He’s something else. Something that’s been feeding on us for 800 years.”
“Then who is he?”
“I don’t know,” she said. “But he’s why we’re all waking up at the same time.”
The door opened.
Kaito.
He looked at Sora. Then at Ren.
His expression didn’t change. But his hand twitched toward where a sword would be.
Sora smiled at him. “Kaito. Still playing the villain?”
“Still playing the saint, Sora?” Kaito shot back.
The tension was so thick Ren could taste it.
Sora turned to Ren. “Go to class. And Ren? If you see Hayato again, don’t fight him. Run. He’s not stable yet.”
“Why are you helping me?” Ren asked.
“Because someone has to,” Sora said. “Now go. Before Kaito does something stupid.”
Ren left. Kaito followed.
In the hallway, Kaito grabbed Ren’s arm.
“She’s lying,” he said.
“About what?”
“About everything,” Kaito said. “Especially about you.”
*3:40 PM. The walk home.*
The sky was that wrong red again.
Ren could feel it in his teeth. Something was coming.
“Don’t go the main road,” Kaito said. He was walking half a step behind, eyes scanning rooftops.
“Why?”
“Because he’s already here.”
As if on cue, the streetlights flickered and died.
Every car alarm in a 3-block radius went off at once.
And from the alley between two buildings, he stepped out.
Hayato.
No glasses. No school uniform. Just armor. Black. Cracked.
And no face. Just smooth skin where eyes and mouth should be.
The nodachi in his hand dragged on the pavement, leaving a line of frost.
“Ren,” Kaito said, drawing a wooden practice sword from nowhere. It ignited with blue flame. “Run.”
“I’m not running anymore,” Ren said. His voice was steady. Too steady.
Hayato tilted his head. Like he was listening to something.
Then he charged.
No warning. No words.
Just 200 kilos of rage moving at the speed of a car.
Kaito intercepted.
Their weapons met with a sound like thunder.
The shockwave blew out windows.
“Go!” Kaito shouted, already being pushed back.
Ren didn’t.
Because this was his fault.
This was the boy he’d led to die 800 years ago.
This was the friend he’d left faceless.
_“FIGHT,”_ the old voice said.
_“RUN,”_ the new voice said.
Ren chose a third option.
He stepped forward.
Hayato’s nodachi came down.
Ren raised his hands.
And the air _answered_.
Blue light exploded from his palms. Not the faint glow from before. This was real.
It formed a wall.
The nodachi hit it and stopped.
Hayato recoiled. For the first time, his head tilted the other way. Confused.
Ren felt it now. The memories weren’t just memories.
They were power.
800 years of war. 800 years of guilt.
All of it was in his blood.
He slammed his hands down.
The blue light shot along the ground and erupted under Hayato’s feet.
Hayato was thrown back into a wall. Concrete cracked.
But he stood up. Slowly.
And the blank face turned toward Ren.
Then it _opened_.
A mouth tore itself across where none had been.
And it screamed.
It wasn’t human. It was every soldier who’d died on that battlefield, screaming through one throat.
Ren dropped to his knees, hands over his ears. Blood ran from his nose.
“Ren!” Kaito was at his side, shielding him. “You have to get up! He’s not done!”
Hayato raised the nodachi for a finishing blow.
And then —
“Stop.”
The word was soft. But it cut through the scream like a blade.
Everyone froze.
Standing on top of a parked car was R.
School uniform. Glasses. Hands in pockets. Smiling.
Like he’d been waiting for this exact moment.
“Hayato,” R said. “Stand down.”
Hayato lowered the sword. The mouth on his face closed.
R jumped down. Walked between them like this was a normal Tuesday.
He stopped in front of Ren.
Crooked down to eye level.
“You did good,” R said. “Really. Most people would’ve died there.”
“Who are you?” Ren gasped.
“Me?” R pushed up his glasses. “I’m the reason you’re all back.”
He looked at Kaito. At Sora, who had just arrived at the end of the street. At Yumi, watching from a rooftop.
“800 years ago, you five generals killed each other over a war that didn’t matter. And your hatred was so strong, it tore a hole in the world.”
R tapped his chest. “I fell through that hole. And I’ve been hungry ever since.”
Kaito’s sword went out. “You’ve been feeding on us.”
“Feeding, guiding, reb
