The night air in Kyoto was thick with the scent of rain. The streets shimmered under the pale glow of flickering lamps, casting ghostly reflections onto the slick cobblestones. Inosun Ichiguro kept his hood up as he slipped through the back gate of Kyoto High, heart racing. He wasn’t supposed to be here — not at this hour.

But tonight wasn’t just any night.

Inosun had been dragged into this by Fushigini, the calm but cunning second-year, and Toshimaru, whose piercing eyes always seemed to hide more than they revealed. The three of them stood in the shadow of the old temple building, its wooden walls groaning under the weight of centuries.

In Toshimaru’s hands was an ancient scroll, bound in deep crimson silk and sealed with a black wax emblem shaped like twin serpents devouring each other.

> “This isn’t just some history club project, is it?” Inosun whispered, eyeing the scroll.

Fushigini smirked. “Not even close. They say this scroll is cursed. But if we unseal it… it will grant us a glimpse of power beyond anything we’ve ever known.”

Inosun felt a shiver crawl up his spine. His instincts screamed to walk away. But another part of him — the reckless part — wanted to see. To know.

Toshimaru’s voice was low, almost trembling. “Once we break this seal, there’s no turning back.”

The wax cracked with a sound far too loud for the quiet night. The silk wrapping fell away, revealing strange black ink symbols that pulsed faintly like veins of light. The wind picked up, howling through the temple, and the air grew heavier — thicker — as if the world itself was holding its breath.

Suddenly, the ground trembled.

From the darkness beyond the temple gates came a low, guttural growl. Two glowing, beastly eyes emerged from the shadows. The creature was massive, its body shifting between flesh and smoke, its fangs glinting under the moonlight.

> “We… we woke it up,” Fushigini stammered.

The scroll tore itself from Toshimaru’s hands, floating into the air. Black tendrils lashed out, coiling around Inosun’s arm like chains.

Pain. A burning, searing pain shot through his body, and a voice echoed inside his mind.

> "At last… freedom."

Inosun’s knees buckled, but the voice continued, deep and ancient.

> "I am Rioten Tangent… and now, boy, I live within you."

Visions flashed — an endless battlefield soaked in blood, a man with the same eyes as Inosun but darker, crueler, wielding a blade of pure shadow. Another voice rose, laughter echoing through the chaos.

The beast lunged, but Inosun’s body moved on its own, his hand snapping up. A burst of black energy exploded from his palm, slamming the creature into the temple wall.

The scroll dropped, lifeless and burned.

Inosun gasped, clutching his chest. Fushigini and Toshimaru stared at him, their faces pale.

> “What… was that?” Toshimaru asked, almost afraid of the answer.

Inosun didn’t know. But deep inside, Rioten’s voice whispered again.

> "Collect the fragments… or you will die. My brother rises, and if he returns first… both our souls are doomed."

The wind died down. The night seemed calm again, but Inosun knew it wasn’t over. The seal was broken. The curse had begun.

And somewhere in the darkness, another pair of eyes was watching.

The temple air grew colder. Inosun, Toshimaru, and Fushigini froze as a shadow crawled along the walls — two glowing, blood-red eyes cutting through the darkness.

Before any of them could scream, the creature lunged.

Its jagged maw opened unnaturally wide, and in a horrifying instant, Toshimaru vanished inside. No chewing. No sound. Just gone.

Fushigini’s cry was cut short as the monster’s eyes flashed again. It swallowed her too, as if she’d never existed.

Inosun’s legs moved before his mind caught up. He sprinted toward the exit, panic clawing at his chest. Lanterns crashed against the walls as he threw them one after another — flames exploding, shadows writhing — but the beast was faster.

Its claws scraped stone. Its breath was rancid. It was on him.

Just as its jaws closed, Inosun’s hand brushed against the cursed object hanging at his side. Instinct — or desperation — took over. He smashed it into the ground.

A surge of burning light erupted from the shards, flooding his veins with power. He didn’t think. He attacked.

The next thing he knew, he was inside the beast — no, ripping it apart from within. Blood and shadow spilled in every direction. The monster roared, its body unraveling into smoke.

In the fading darkness, a voice spoke from somewhere deep inside his mind.

"I am Rioten Tangen. You have broken my curse. I will house your soul… to take my revenge on my brother."

Inosun collapsed, gasping. He staggered to where Toshimaru and Fushigini lay on the ground. Their bodies were whole, but they did not wake.

Then came the tearing. A wrenching pain that split him in two. His vision went white.

When it cleared, he was no longer in the temple.

He stood in a vast, endless void. Before him, a throne of black stone rose from the mist. Upon it sat a tall figure, crowned in gold, eyes glowing like the beast’s — yet colder.

"I am Rioten… and you are now bound to me."

The darkness around Inosun began to shift, thick with heat and a strange pulse. A voice echoed inside his skull, deep and ancient.

"I am Rioten Tangen…"

Before Inosun could speak, the shadows parted. He saw a man seated upon a throne of molten rock, a crown of fire burning above his head.

"Let me tell you a story," Rioten said, his voice like crackling embers.

"I was born from the Spirit Realm Orb — created alongside my brother. I wielded fire, he wielded ice. We were brothers not by blood, but by creation itself… and we loved each other.

But the Eight Clans feared us. They knew that if our elements ever fused, it would create the Heaven’s Violet Void — a divine force capable of erasing not just flesh, but soul, spirit… even entire worlds.

So, they tore us apart.

I learned to use my fire to heal — to restore even the cells of the dead. My brother… he used his ice to destroy, freezing kingdoms in his pride. Over time, I grew humble. He… became arrogant.

Six hundred and sixty years ago, we met on the battlefield. Fire clashed with ice, and our powers merged… birthing the Heaven’s Violet Void. The explosion tore open the boundaries between realms, allowing magic beasts to spill into the human world.

The Maru Clan and the Ooni-chan of the Satano Clan sealed us away that day, shattering our souls into twenty fragments, scattering them across worlds.

And now, Inosun…" Rioten leaned forward, his burning eyes locking with Inosun’s trembling gaze. "My mission is to restore my soul. And for that… I need you."

Let's form a pact rioten said allowing inosun to live a normal life in exchange for restoring him to achieve his mission but inosuns brain couldn't carry the meaning of a pact "dumbass a pact is an agreement between us and if you don't adhere to it you will be punished by nature and pick up that scroll it gives me the ability to seal someone in it" rioten tangen said so he let inosun out. He goes back to school at kabusaki high but he never saw fushigini and toshimaru there again he hanged out with his friends reo and yoshino and forgot about the roles that awaits him to play.

Part two at a Tokyo station at night a boy of sixteen years is seen with a scroll and an object his name was toma nishido he had broken the curse of rioten teakuna (tangens brother) he told toma about his brother and his past life. Toma agreed to do it for him to join the Tokyo jinkai high and they forged a pact this episode had triggered the awakening of the twin souls in order to hunt scrolls before it was too late

The late afternoon sun spilled golden light across the quiet Kyoto streets. Inosun, Reo, and Yoshino walked side-by-side, their schoolbags swaying gently. The conversation was warm, casual—just friends winding down after a long day.

“So…” Yoshino sighed, kicking at a pebble on the sidewalk. “Midterm results are out. I don’t think I’ll ever understand physics. Thirty out of a hundred… that’s basically a crime.”

Reo chuckled, pushing his hands into his pockets. “Don’t feel bad. Some of us are born for numbers, some aren’t. Speaking of numbers—top score in math, right here.” He smirked.

Inosun didn’t gloat or tease. Instead, he pulled a rolled-up sketch from his bag. “And some of us are born for art,” he said quietly. Unrolling the paper revealed a bold, perfectly shaded drawing of Sung Jinwoo, every line precise and alive with energy.

“Whoa,” Yoshino’s eyes widened. “You drew that?”

“Hundred in arts,” Inosun replied with a small grin. “Guess I’m the Sung Jinwoo of the pencil.”

They laughed—but far away, in the shadows of an old temple, two cloaked figures watched them. The wind carried faint whispers.

From the alleys, figures in dark robes emerged — members of the Cult of the Twin Soul. Before the friends could react, hands covered their mouths, ropes bound their wrists, and the world went black.

---

When Inosun opened his eyes, he was in a cold, damp room. Dim lantern light flickered over cruel faces.

“They will restore the Twin Souls,” a cultist hissed.

The beating started. Harsh blows, mocking insults, and laughter. Reo’s lip bled, Yoshino trembled, but Inosun’s glare never wavered.

“Enough,” he said through clenched teeth. “You touch them again, and you’ll regret it.”

The cultists dragged him to a darker chamber. There, they drew a syringe and plunged it into his arm. But every time they tried to take his blood, it melted into steam in their hands, burning their skin.

“Impossible…” one muttered.

“His blood rejects us,” another spat.

Frustrated, they stuffed all three into a truck bound for Africa — a one-way trip to execution.

---

What the cult didn’t know was that the miracle talisman hidden in Inosun’s clothes had already activated, sending a silent signal to Vice Captain Yoshini Jinhuu of the Kyoto Jinkai High Defense District.

The truck screeched to a halt as explosions lit up the night. Yoshini stepped out of the smoke, his blade glinting in the moonlight.

“You picked the wrong students,” he said coldly.

But before he could free them, a gun pressed against Inosun’s head. The trigger pulled.

---

When Inosun awoke, he was lying in a hospital bed, the scent of antiseptic filling the room. Reo and Yoshino were beside him, both bandaged but alive.

The door slid open. Vice Captain Yoshini entered, his sharp eyes studying them.

“You,” he said to Inosun. “You broke the Rioten Curse… didn’t you?”

Silence.

He finally sighed. “Then you have no choice. All three of you will transfer to Kyoto Jinkai High Defense Training Base. You’re targets now — and the war has just begun.”
