The lift doors slid open.
Dr. Raizen looked up casually—
Then froze.
Emika's unconscious body hung over Hatsume's shoulder.
His smile disappeared instantly.
"…What happened to her, Hatsume?"
Hatsume stepped out without slowing. His grip on her tightened slightly.
"She was poisoned by Shiori," he said quickly.
Raizen's eyes darkened.
"Bring her to the chamber. I'll get the antidote."
No hesitation.
They moved fast down the corridor. Kaito followed silently, his gaze fixed on Emika. His jaw was tight, but he said nothing.
The chamber door opened.
Inside, it looked like an operating room fused with a research lab — surgical lights overhead, metal tables, shelves lined with vials and instruments.
Hatsume laid Emika carefully on the bed.
Shion moved to a cabinet, took out a saline bag, and set it up without a word. The needle slid into her arm. Clear fluid began to drip.
A moment later, Raizen rushed in holding a small serum bottle and a syringe.
He drew the liquid carefully.
Injected it.
Everyone waited.
A few seconds passed.
The monitor steadied.
Emika's breathing deepened slightly.
Raizen exhaled.
"…Good grief. She'll recover by tomorrow."
Relief flickered across his face before it vanished behind composure.
Kaito hadn't spoken once.
He stood near emika, eyes shadowed, watching everything.
Then Shion glanced at him.
"Let her rest for today," he said lightly. "Come. I'll show you around."
That was enough.
Kaito finally spoke.
"Who are you?"
His voice was calm, but cold.
"Why did you take us from there?"
His eyes narrowed.
"Or should I assume this was kidnapping?"
A brief silence.
Tenshiro shifted slightly, the faint sound of chains brushing against each other.
Shion laughed softly.
"Good grief. I knew you'd say that."
He stepped forward, hands in his pockets.
"Relax. Let me introduce us."
He tapped his chest.
"I'm Shion. The mud user. I made the floor muddy on the rooftop."
He nodded toward Hatsume.
"That's Hatsume. He controls the wind — the tornado."
Hatsume stood quietly, expression unreadable.
Shion tilted his head toward the last man.
"And the one who tied you up with chains? That's Tenshiro."
Tenshiro met Kaito's gaze without emotion.
The room felt still.
Raizen gave Emika one last look before turning away.
"Let's talk, Kaito," he said calmly. "I think it's time you understood a few things."
He glanced at the others."Shion. Hatsume. Tenshiro. You're coming."
Shion pushed off the wall without a word. Hatsume followed, hands in his pockets.
Tenshiro didn't move at first.
His jaw was tight. Eyes hard.
But after a second, he stepped forward anyway.
They walked down a long hallway lit by dim overhead lights. Their footsteps echoed softly.
Raizen spoke as they moved.
"This place is our hideout."
Kaito frowned slightly. "Hideout?"
From behind him, Hatsume let out a quiet laugh.
"Well… because what we do isn't exactly legal."
Kaito stopped walking.
The shift was immediate.
His shoulders squared. His gaze sharpened. He took a small step back, putting distance between himself and the group.
"Illegal how?" His voice was steady, but edged. "You mean like the people who kidnapped me? Injecting serums. Experimenting on humans."
His stare didn't waver.
"Is that what you are?"
The hallway fell silent.
For a brief moment, Raizen actually laughed — short, almost surprised.
Then he turned his head slowly toward Hatsume.
"Don't make this harder than it needs to be," he said quietly. It wasn't loud, but it carried weight.
Hatsume's smile faded.
Raizen looked back at Kaito.
"I'll explain. But not here. Walk with me."
After a pause, Kaito followed.
They stopped in front of a wooden door. Raizen opened it.
The room inside looked chaotic — whiteboards covered in notes, red strings connecting pinned documents, research papers scattered across tables, old files stacked in unstable piles. It smelled faintly of ink and coffee.
"Come in," Raizen said. "Ignore the mess. Organization isn't my strength."
Shion smirked faintly at that.
Raizen walked to a small coffee machine in the corner. He grabbed a plastic cup, filled it, then poured another for himself.
He handed one to Kaito.
"It'll be a long conversation."
Kaito didn't take it immediately.
His eyes studied the cup carefully.
Raizen noticed.
A faint smile tugged at his lips.
"You think I'd poison you after saving the girl?" He took a slow sip from his own cup. "If I wanted you dead, there were easier opportunities."
A beat passed.
Kaito finally accepted the coffee but didn't drink.
The others poured cups for themselves and sat down.
Tenshiro leaned back in his chair, arms crossed, still visibly irritated. Shion looked relaxed, but his eyes were attentive. Hatsume rested one elbow on the table, watching Kaito with mild curiosity.
Raizen sat opposite Kaito and folded his hands on the table.
For a moment, he simply observed him.
Then he leaned forward slightly.
"Let's begin with something simple."
His gaze sharpened behind his glasses.
"How did you survive after injecting Calistain?"
The word hung heavy in the air.
"And more importantly," Raizen continued calmly, "why did you inject it in the first place?"
Kaito frowned, confusion flickering across his face."What do you mean by Calistain?"
Raizen didn't answer immediately. He watched him carefully, then spoke in a low, steady voice.
"Do you remember the day you were walking your cat in the park? Your cat kept staring at a man who was holding a serum. You were carrying the same type of serum too. When a dog suddenly barked, both of your hands shook… the bottles fell… and they got exchanged by accident."
For a second, Kaito's eyes widened. Then he nodded slowly.
"Yes… I remember." His voice turned firm, almost proud. "After that, I got superhuman strength. It felt unnatural… but I thought it was because of the serum."
Raizen shifted his gaze toward Shion.
"The man you exchanged the serum with… was Shion."
Kaito turned to look at Shion, trying to search his memory. He forced himself to recall that day—the park, the barking dog, the bottles falling—but when it came to the man's face… there was nothing.
"I… I didn't look at his face," Kaito admitted quietly.
Shion met his eyes with a serious expression.
"That day… when I returned home," Shion said slowly, "I opened my suitcase and almost had a heart attack. Inside… was a cat's vaccine."
Tenshiro burst into loud laughter.
"That's because you're an idiot, Shion!"
Raizen shot him a sharp look. "Enough. Calm down." Then he turned back to Kaito. "Now tell me… why did you inject that serum?"
Kaito's confident posture crumbled. His shoulders dropped. His voice grew heavy.
"Frankly… the serum wasn't for me." He swallowed. "It was for my cat. I live alone. She… she was the only family I had."
His fingers trembled slightly.
"She was sick that night. I bought the vaccine from the store for her. I thought I was saving her."
He closed his eyes, as if the memory itself hurt.
"When I injected it into her… she screamed. Her body started expanding unnaturally—like someone was pumping air into her from the inside. She kept screaming…" His voice broke. "Then she exploded."
The room felt colder.
"Parts of her body were everywhere."
No one moved.
"I lost control," Kaito continued, his breathing uneven now. "I couldn't think. I was full of rage. I went straight to the medicine shop and beat the owner until he was unconscious."
His fist clenched tightly.
"After that… I realized it was my fault. I killed the only family I had." His voice cracked completely now. "So I decided to inject the serum into myself too. I wanted to follow her. I didn't want to live without her."
He looked down at his hands.
"But the next day… I woke up." His expression twisted with pain. "I couldn't remember anything at first. Just this immense strength. Later, my memory came back… but I still don't understand why I survived…"
His eyes turned red with frustration and grief.
"Why did I survive… when she had to die?!"
He slammed his fist onto the table.
The sound echoed through the room.
Silence followed.
No one spoke. Not even Tenshiro.
Their chests felt tight. The air itself seemed heavy.
Shion lowered his head, his expression filled with guilt. When he finally spoke, his voice trembled.
"I'm sorry… It was my fault." Tears slipped down his face. "If I had been more careful… none of this would have happened. Your cat wouldn't have died."
He wiped his eyes, but more tears fell.
"I'm really… really sorry about your cat."
Tenshiros expression turned unusually serious.
"It's not only his fault," he said firmly. "It's ours too. We should've been more careful. If we had paid attention, none of this would've happened." He exhaled slowly. "But because of that mistake… you're involved with us now."
Kaito listened quietly. His breathing had finally steadied.
"No," he said calmly. "It's okay. Her death isn't your fault. It was an accident." He looked down for a second, then forced a faint, fragile smile. "Maybe… it was her fate at that time."
The words sounded accepting, but the pain behind them was still raw.
He lifted his head again, his expression turning serious.
"I know the strength I gained isn't normal," he continued. "And the fact that it adjusted to my body… that's not normal either."
His eyes shifted toward Raizen.
"What do you guys mean by 'involved'?"
Raizen slowly adjusted his glasses. The small reflection on the lenses hid his eyes for a moment. When he looked back at Kaito, his face was completely serious.
"Before I answer that," Raizen said evenly, "you need to understand the power you carry."
The room grew still again.
"I'll explain everything ."
We went to a remote island for vacation and discovered six different types of stones. Each stone had a distinct color and structure, clearly different from normal minerals. Out of curiosity we brought them back to the lab for testing. After several experiments, we found that when the stones were dissolved under special conditions, we converted into six different serums .
Each one gave a different kind of powers.
We named according their aura :
Avelior, Caelisera, Elmyrion, Kaelvane, Sylvaris, and Calistain.
Avelior – The Nature Enhancer
Avelior allowed a person to control one element of nature.
Water.Wind.Fire.Earth.
But only one.
If someone awakened wind, they could never use fire.If someone controlled water, they could not control earth.
Each user was bound to a single element for life.
An Avelior user could shape their element into weapons — blades made of wind, spears of fire, whips of water, walls of earth. They didn't just summon the element; they controlled its shape and movement freely.
Caelisera user could use Lightning and Healing .
A user could throw lightning like a thunderbolt. They could shape electricity into weapons and even travel through electrical wires and enter devices, giving access to systems and machines.
The second power was healing.
They could close wounds, restore damaged tissue, and stabilize dying people.
However, most users naturally awakened one power more strongly than the other.
If someone was stronger in electricity, healing required intense training.If someone was gifted in healing, mastering lightning was difficult.
They could use both.
But it demanded discipline.
Elmyrion gave one of two abilities.
Never both.
The first was mind control.
A user could control someone's actions. They could erase memories, add false ones, or command a person like a puppet. Strong users could even rewrite parts of someone's personality.
The second ability was shadow control.
If the user stepped into someone's shadow, they could control that person's movements. The victim would move as the shadow moved.
But again, only one power appeared per user.
If someone had mind control, they could never use shadow control.
Kaelvane granted two powers that worked together.
Chain authority and blood authority.
The user could summon steel chains from their hands . They could use them as weapons, shields, or bindings.
The chains were strong and flexible, controlled fully by the user's will.
But the true danger came from blood.
If an enemy's blood touched the chain, that enemy would freeze for a short time. Their body would lock completely.
Unlike some other enhancers, Kaelvane users could use both of their powers at the same time.
Sylvaris also gave two possible abilities.
But like Elmyrion, a person could only awaken one.
The first was time authority.
The user could pause time briefly. Or move a few seconds into the past or future. Not minutes. Not hours. Only seconds.
The second ability was density control.
The user could make their body harder than steel. They could increase or decrease the weight of objects or people just by touching them.
They could make a weapon incredibly heavy.Or make something large feel almost weightless.
However, a time user could never use density.
And a density user could never control time.
Calistain – The Legendary Enhancer
Calistain was the rarest and strongest of all.
It granted superhuman strength, incredible speed, and intelligence that could reach an IQ of 230.
A Calistain user could learn weapons extremely fast. Their reaction speed was far beyond normal humans. Their body was naturally superior.
But what made Calistain legendary was its final stage.
If someone completely mastered Calistain, they could begin to use other enhancers' powers.
Not fully at first.
But gradually.
They could imitate Avelior, use parts of Caelisera, or even tap into abilities like Kaelvane.
This made Calistain users extremely dangerous.
However… there were two rare antibodies were founded in the human body. One is Salferin andd another Varlean.
Salferin existed in only five percent of the entire human race . Rare — but not impossible to locate one .
However varlean?
Almost extinct.
Only 0.03% of humanity carriee this antibody. Making them the most rarest human in the world .
However those who possessed them were different. Their immune systems were abnormal — unnaturally resilient. They fell sick less. They healed faster. Their bodies rejected death more stubbornly than ordinary humans.
That's when the Vaeloris serums were comes handy
Avelior.Caelisera.Elmyrion.Kaelvane.Sylvaris.
Each one triggered a violent viral reaction inside human body. For normal humans, the reaction was immediate — the immune system collapsed, organs failed, cells devoured from within.
Death didn't take minutes.
Only people with antibodies like Salferin could survive these five.
Survive.
Not endure
Because survival came with a price.
The pain was indescribable — nerves burning, bones vibrating, thoughts shattering under pressure. The brain was pushed beyond its natural limits. Many with Safelin lasted a few moments… before their minds broke.
And when the mind broke —
The serum rejected the body.
And the body died.
But only few of the strongest minds were survived . Mind which has a strong will . A really strong will to obtain the powers from the vaeloris.
Afterwords slowly the vaeloris adjusted through out the body
But Calistain…
Calistain was different.
Only those carrying Varlean could even remain alive after injection.
Yet even that was not enough.
Calistain did not merely attack the body.
It examined the mind.
It dragged the user to the edge of death and waited.
The pain felt final.
Absolute.
Like drowning inside your own bloodstream.
And the moment you resist —
You die .
Because Calistain did not choose the strongest body.
It chose something else.
It chose someone who had already accepted death.
Not reckless.
Not desperate.
But someone who had truly, completely decided—
"I am ready to die."
Only then did Calistain open itself.
Only then did it grant its full power.
Raizen slowly lifted his gaze.
His eyes locked onto Kaito.
Cold.
Steady.
"When you injected the serum…" he said quietly, almost gently,
"your intention was pure."
Kaito's breath caught.
"You didn't want to survive."
A pause.
"You wanted to die and that was why it accepted you " .
Kaito froze.
His mind went blank.
Kaito was still confused by everything he had heard, yet his eyes never left Raizen's face.
"I understand," Kaito said slowly. "So Calistain was the power I injected. And you're saying my body carries the antibody that only 0.03 percent of humans have."
Raizen gave him a sharp look. "That's correct. However, it was a complete coincidence that you obtained that power."
Kaito leaned forward, his gaze hardening. He briefly glanced at Tenshiro and Shion before looking back at Raizen.
"Then what was your purpose with this power?"
Raizen glanced at Tenshiro and Hatsume, then leaned back in his chair, composed.
"To defeat Edward."
Kaito's eyes widened slightly. "Who is Edward?"
Raizen replied calmly, "The man responsible for kidnapping you. Our organization exists for one purpose — the execution of Edward and his group."
Kaito frowned. "Why did he kidnap me? What was his objective?"
Raizen's expression turned serious.
"He wants to eradicate humanity as it exists now. That's why he's building an army. We are currently his greatest threat because we possess the Vaeloris potions. Edward has acquired a few, but he does not have Calistain. There was only one portion, and you used it completely. That is why he wants you."
He continued, his tone steady but cold. "The group that abducted you is known as the Phantom Unit. Ryussei is their leader. They are Edward's right hand. Their purpose is to fimd vessels for vaeloris and turn them into their puppets ."
Raizen suddenly slammed his fist onto the table, his jaw tightening.
"I still don't know how many people have been turned into their lab rats… how many have died because of their experiments."
He looked directly at Kaito, his expression grim.
"For the past few years, many people have been reported missing. The news claimed it was the work of an organ trafficking organization."
He paused, his voice turning colder.
"But that wasn't the truth. They weren't victims of organ smugglers. They were taken and used as human test subjects."
He paused, then spoke firmly.
"I know this is a lot to take in, but will you join us to protect innocent people?"
Kaito remained silent, processing everything.
Raizen spoke again. "I understand I am asking a great deal from you. But will you help us?"
Kaito lifted his head slightly.
"I have one question. Is the government involved? Do they know about Edward, about your organization, and about what is coming to this country?"
Raizen lowered his voice.
"Yes. The government and the military are aware. It has not been made public because it would cause widespread panic."
Kaito looked down.
"I understand that you are trying to maintain peace in this country. And I'm grateful that a group like yours exists." He paused briefly. "All my life, I watched fictional stories where having extraordinary power and saving people looked impressive. I used to think that if, by some rare chance, I ever gained such power, I would welcome it."
His hands tightened slightly.
"But now that I have it, I understand what it truly means. The burden it places on someone."
His voice grew heavier.
"I've already endured a lot. My parents died. Their property was taken by my relatives. Because I was unsocial and withdrawn, my classmates looked down on me. Slowly, I rebuilt myself from those broken pieces. Recently, I felt like those pieces had finally formed something stable."
He looked at Raizen, his eyes filled with restrained emotion.
"Please… don't make me fall apart again."
Tenshiro tried to speak. "Bu—"
Raizen silenced him with a slight wave of his hand.
Raizen looked at Kaito for a moment, then sighed.
"I apologize for dragging you into this. I should have understood your feelings before asking you to join us." He leaned back. "You are free to decide. However, the Phantom Unit will continue to pursue you."
Kaito stood there in silence, thinking.
After a moment, Raizen added, "You may stay here for now. Let me know when you've made your decision. You have your free will."
Kaito's expression suddenly shifted, his eyes sharpening as something urgent surfaced in his memory.
"I need to leave," he said quickly. "There's something I have to check."
Raizen gave him a calm look and leaned back. "The elevator you used earlier — press the ground floor."
Kaito nodded and stepped out without another word.
As he moved quickly down the corridor toward the lift, the memory became clearer.
On the rooftop… before he was taken… the Phantom Unit had knocked both Nagato and the police officers unconscious.
They hadn't taken them.
They had left them there.
"If they were left on the rooftop…" Kaito muttered under his breath, his pace quickening.
They could have woken up confused. Injured. Questioning what happened. Or might taken nagato with them .
"I have to find Nagato."
