The Reigetsu clan was occupied with their daily chores. At the center of the settlement, a massive cauldron brimmed with ingredients prepared for the midday meal. The fire beneath it steadily brought the contents to a gentle simmer. Misaki Hoshigaki, wife of Elder Sōta Hoshigaki, stirred the food with practiced care, while Elder Sōta sat by the riverbank, legs crossed, immersed in meditation as he always was.
Suddenly, a vision struck him.
He saw his clan in danger.
He saw lifeless bodies scattered across the ground.
Panic surged through him. Elder Sōta sprang to his feet.
He looked around. Everything appeared normal. His wife continued cooking. Children played nearby, laughing as they clashed wooden sticks together. Yet despite the calm, an invisible pressure lingered in the air.
Something was wrong.
Elder Sōta: "Yōtsuki! Come here. We need to talk."
At the time, Yōtsuki was twenty years old. Rising from where he sat, he approached the elder with heavy, deliberate steps.
Elder Sōta: "Yōtsuki, my child, there is something important I must discuss with you."
Yōtsuki: "Yes, Elder. You look tense."
Elder Sōta: "Tension? That is irrelevant. You know the power of our clan—the origin of Reikyō and the purpose for which it was created. Do you not?"
Yōtsuki: "Yes. No Reikyō user in our clan is uneducated. But… I don't understand why you bring this up now."
Elder Sōta: "If you know, then tell me what you know."
Yōtsuki: "Reikyō was discovered two years ago by the previous generation—your father—to counter the Konkai attacks on our clan. It proved extremely effective. Of course… your father passed away from old age a year ago."
Elder Sōta: "Do you know the color of my father's Reikyō?"
Yōtsuki: "No. I do not."
Elder Sōta: "It was the color of the Moon. Purple Reikyō. The first Reikyō to emerge in defiance of Konkai cruelty. I once told you the strongest Reikyō is black—yours. But that was not the full truth. The most powerful Reikyō… is purple."
Yōtsuki: "Purple? But aren't there only five Reikyō colors? Black, white, red, blue, and green. Where does purple come from? And what kind of power does it hold?"
Elder Sōta: "Even I do not know, child. There were only two ways to learn. One—from my father. But he passed before revealing its secrets. The second… from another purple Reikyō user. His name was Cleistois. He left the clan long ago. No one knows where he is now—or what he has become."
Yōtsuki: "You've told me all this, but my Reikyō is black. I can't change that."
Elder Sōta: "You can, Yōtsuki. What you must do is uncover the secret of the purple Reikyō."
Yōtsuki: "How?"
Elder Sōta: "Explore the world. Seek other Reikyō users. Learn from them. I trust you."
Yōtsuki: "And once I do?"
Elder Sōta: "Protect our clan. That is all I ask. As for your own purpose… you must discover that yourself."
Yōtsuki: "Understood."
That night, Yōtsuki ate his meal and slept. In his dreams, he saw himself walking far away from the clan, deeper and deeper into unknown lands. When dawn came, he prepared quietly. He took his katana, some food, and water.
"I'm leaving," he told Elder Sōta.
He planned to travel by day and return by night.
Yōtsuki ventured deep into the forest, encountering various clans. He learned that many were connected to the Migonia Tribe and had heard of the terror it spread. Entire communities lived in fear of Migonia's Konkai users. Yōtsuki asked questions, investigated relentlessly—but no one knew of Cleistois. No one spoke of the Moon Reikyō. Some barely understood Reikyō at all.
The first day ended in failure.
As night fell, Yōtsuki began his return.
Then he saw it.
Smoke.
Thick, black smoke devoured the sky above his village.
A chill ran through his body. Fear seized his heart. He ran.
When he arrived, the world had ended.
Bodies lay scattered across the ground. Flames consumed shelters. The air reeked of blood and ash. Yōtsuki stood frozen, unable to understand what had happened—or why.
Then he saw him.
Elder Sōta lay on the ground, drenched in blood.
Yōtsuki rushed forward, cradling the elder's head.
Yōtsuki: "You can't die! Elder Sōta! Not now… please… don't leave me alone!"
Elder Sōta opened his eyes and grasped Yōtsuki's arm, staring deeply into him.
Elder Sōta: "Yōtsuki… do not fall to hatred. Do not seek revenge against those who destroyed our clan. My final wish… is that you find your father… Cleistois."
Yōtsuki: "The legendary Cleistois… is my father?"
A faint smile formed on the elder's lips.
Yōtsuki: "Wait! Don't leave me!"
Elder Sōta: "You are never alone, my child. Your soul will always walk with you."
His eyes closed.
Yōtsuki screamed—and broke down.
He buried the unscathed bodies of his clan, along with Elder Sōta and Misaki. Then, gripping his katana, he walked onward—alone—beginning the path toward his true purpose.
Morizuki was in tears.
Morizuki: "No… I'm so sorry for your loss, sir. I will follow you forever."
Engetsu: "So… these are the colors of Reikyō…"
Morizuki: "Hey! What are you saying?! He just told us a tragic story! All you care about is power, you bastard!"
Engetsu: "Huh? Bastard? That's you!"
They lunged at each other.
Hyōgetsu: "Hmm…"
Yōtsuki forced them apart.
Yōtsuki: "Listen carefully. If you wish to learn Reikyō, you must first unite your soul and body."
Morizuki tilted his head.
Morizuki: "…?"
Yōtsuki: "In simple terms—meditation and physical training."
Engetsu: "Training is fine. But meditation? What does that have to do with anything?"
Yōtsuki: "How do you expect to connect with your soul otherwise?"
Engetsu: "Sounds pointless."
Yōtsuki: "Then you will never wield Reikyō. Now—let us begin with exercise."
He led them into a forest clearing. There, they trained relentlessly—push-ups, sit-ups, long-distance runs.
For one full week, they trained using nothing but traditional methods.
