Twenty million years ago, there was the Great Earth, which was the junction of three planets, including Earth.
On that large planet lived the Osmo and the humans. Humans were living under a great persecution: the Osmo fed on their energy to grow stronger. The more human energy they consumed, the stronger they became.
The Osmo born from the death of a human were already of a superior class, as they possessed immense strength from birth.
This superior being had a more human-like appearance and could speak like humans. During this period, the Creator-Father, as the Osmo called him, was the great lord Oki, the creator of all Osmo.
The Infinires, three supreme beings, emerged. After a brutal 10-day battle, they used their bodies to seal the great lord Oki. Without lord Oki, the Great Earth split into three planets: Venus, Earth, and Mars.
The Osmo were no longer being born, and the living Osmo began to die without the great lord Oki's energy.
But before being sealed, the great lord Oki preserved a bit of his energy—so little that it could barely be felt—and hid it inside a wooden frog.
The Earth was already reverting back to forest.
Fifty years later, with no Osmo remaining, the energy inside the wooden frog began to grow little by little, capturing energy from human beings. Two children were playing, and one of the boys found the wooden frog. When he touched the frog, the energy transferred into his body.
Twenty years passed. The energy remained in his body, growing. He could not have children, which was his wife's dream.
They prayed intensely for a child, seeking a miracle, until she became pregnant. At that moment, she was carrying Oki's first child, created from his energy.
When the child was born, it was stillborn. It remained so for 30 minutes and then came back to life. The child grew, its energy grew and was passed on to its own child, and from child to child, generating many Sons of Oki. Osmo began to appear again, feeding on human emotions.
As time went on, the Osmo had to adapt to the new world. At the moment of the sealing, the Infinires gave a bit of their energy to create their Osmo descendants with good energy. These were created from people who had suffered a violent death and endured much in life, but who had always been good people. This type of Osmo would fuse with human beings.
"Welcome to TATORO Elementary Preparatory School! Here, you will all learn how to control your powers."
"I am your teacher, Yagato Matsuki, but you can call me Sensei."
Sensei Yagato gave a warm smile, trying to diffuse the stiffness in the room.
"Come on, everyone! Don't be shy, you can introduce yourselves and show a little bit of your style!"
"I am Zaren Agarin, from the Agarin clan, an elite spirit controller, class 3."
Zaren had the naturally active posture of his clan, the Agarin. They are capable of controlling elite spirits, which are classified according to their strength.
"I am Zulian Wang, from the Wang clan."
The Mixed-Blood Clan of Zulian carries the honor of being able to control the rare Celestial Dragon Spirits.
"I am Nanai, I don't come from a clan."
Nanai was an Osmo, a person who connects with spirits, and his power was undeniable. His spirit was classified as elite level 4.
"I am Fukuoka."
Fukuoka's voice was a hoarse whisper, carrying a weight that went beyond his years. Another elite Osmo, he connected to a spirit at the moment darkness was about to swallow him, on the verge of suicide on the train tracks. With an alcoholic father who marked him with violence and a younger sister who killed herself at 14, he carried countless scars on his skin, not just physical ones.
His negligent mother worked the streets of Tokyo in prostitution and was killed by an obsessed client. The spirit that saved him has no classification; it is of a special level.
"And this is Sensei Nobaru Monuki."
Yagato introduced her with a flash of caution in his eyes.
Nobaru stepped forward, and the room's temperature seemed to drop.
"Hello, you bastards."
The greeting was sharp.
"There are a few ways to connect with an Osmo:
An Osmo connects to you
You are from a clan
You are the child of a spirit and a human."
Nobaru was the third option. She possessed power that defied logic. Her mother, a human, fell deeply in love with her father. He tragically died in an accident, but their love was so intense that he manifested as an Osmo, retaining all his memories, and fathering Nobaru: a human with supernatural powers, capable of controlling any spirit. She was one of the 26 elites in the academy, boasting position 18.
"Agarin, one step forward. Your power even resembles mine."
Nobaru's tone was pure challenge.
"Summon your strongest spirits. Let's do a recognition for your clan."
Zaren Agarin felt a shiver of nervous excitement run down his spine. The woman's arrogance was palpable, and he accepted the challenge instantly.
"Summon, Seal Break."
The spirit materialized with the fury of a storm.
"Your spirit is quite strong."
Nobaru showed no fear. She grabbed her axe, and a dense, crushing energy burst forth, making Zaren gasp for breath. She handled it with the indifference of someone crushing an insect and shattered his spirit in a second. The sound of the impact echoed like thunder.
Zaren stood paralyzed, eyes wide, watching the remnants of his strength be swept away like dust. The defeat was instantaneous and humiliating.
Nobaru lowered her axe, a cold, sadistic smile spreading across her face.
"He's quite strong, but it's a shame his controller is so weak." Chuckle
