After experiencing a great battle on the Elemental Continent, in the Battle against Ishiki Otsutsuki, who served as the vessel for Abe Matsumoto, one of the 10 Grand Masters of the Death Game. From Earth in T
In a misty intermediate dimension, a place where the laws of space and time are warped after the great war, three souls from completely different realities are brought together by an invisible thread of fate.
Ani Angraeni, the girl whose fate on Earth was bound by physical paralysis, now stands tall. In this supernatural world, her soul manifests in its entirety, radiating a pure spiritual aura. Before her stands Yuuto Iba—a young man from the High School DxD universe who has endured countless battles against fallen angels and demons, carrying a heavy burden on his shoulders.
However, the most intimidating presence among them is Darman Uchiha.
"I have seen the end of the Third Great Ninja War. I fought to the last drop of my blood against Isshiki Otsutsuki, died, and rose again as a Shinigami," Darman murmured, his Sharingan slowly rotating in the darkness, reflecting the flames of death. "But this place... this is not the Pure Land of Shinobi."
Darman Uchiha, now evolved into a mystical entity of death, stepped forward. This meeting of three souls marked the beginning of the unification of the dimensions torn apart by the greed of gods and humans.
II. The Emperor's Disguise and the Dragon Bloodline
In this new supernatural world, the supreme entity no longer always reveals its gigantic form. Great Red, known as the True Dragon Emperor who roams the Dimensional Gap, now reduces his limitless power to live among humans.
[University of Tokyo Student Profile] Name: Great Red (Human Disguise) Appearance: Handsome man, long, flowing red hair Level: Third-Year College/University Student Expertise: Astronomy & Esoteric Astrology Bloodline: He is the heir of the legendary heroes Tornado of Terror (Tatsumaki) and One-Punch Hero (Saitama), and the spiritual reincarnation of the Shinigami Uchiha Darman.
Despite sitting quietly in college, his blood is connected to an incredibly complex network of dragon power. At the top of that hierarchy stands Rose Ryu Gu D, the legendary Red Dragon Queen. Rose is not just a queen; she is Nami's biological mother.
Their family tree stretches across mythical kingdoms:
Rose Ryu Gu Barselion is an official member of the Barselion Family.
She is the younger sister of Dragon King Barselion of the Dragonof Kingdom.
She is the sister-in-law of Erelina Barselion and the direct aunt of Erza Barselion.
This relationship gives Nami and Great Red a very close cousin bond, a mystical genetic anomaly similar to the relationship between Gon Freecss and Monkey D. Luffy—where Gon's and Luffy's mothers are siblings, both daughters of the Heavenly Dragon Emperor, A Rubelion Dragonof.
III. The Holy Grail Conspiracy and the Collapse of Nirvana
While Great Red was living his student life, in a higher dimension, a cosmic storm was raging. For the first time in 50,000 years, the Trimurti of Hindu Mythology gathered in a tense silence.
They had only one purpose: to discuss the destruction of Nirvana, located above the land of China.
The destruction was the result of an apocalyptic battle. Sakra (the god Indra) had vanished from the face of the earth after clashing directly with Madara Uchiha and Kaguya Otsutsuki. Kaguya, with boundless greed, sought to expand her tyrannical rule over Hindu and Buddhist Mythology. This expansion was made all the easier after the Mahayana Buddha Chakravartin was sealed in the Afterlife by Yhwach, the Quincy King.
However, behind all this supernatural chaos, a single human mastermind was pulling the strings of fate from the shadows. He was the victor of the Sixth Holy Grail War, the man who founded the world security organization Chaldea, and the Master of the Great King Solomon:
Marisbury Animusphere.
Under the light of the full moon, it was revealed that Marisbury had successfully created SCABA, a forbidden operating system capable of counterfeiting the Throne of Heroes. Using this system, he manipulated the spirits of heroes for one ultimate goal: the systematic, total annihilation of humanity.
This dimensional shift also reopens the pages of dark past history from various eras:
1. The Great Magic Era (548 AD) — The Destruction of Neverland
In the Neverland Forest, West Germany, stood the Fairy Kingdom of Neverland, ruled by King Oberon Zergion and Queen Titania Vermilion. They were blessed with four daughters and two princes,
Minerva Vermilion, Zarvis Zergion, Asuna Zergion, and Serfersion Vermilion were among them.
After five centuries of peace, disaster struck in the year 1000 AD. The Demon Kings Leviathan and Beelzebub led an armada of demon legions, razing forests from the Netherlands, Belgium, and France, all the way to the heart of Neverland. In desperation, Queen Titania cried out to her loyal guards:
"Mavis, go with your sister Asuna to the east, to the Land of the Rising Sun! Find Yasaka and deliver this letter to her!" "But Mother, I don't want to leave you!" Mavis cried. "Go, Miya! Take them away from here!" the King commanded before the kingdom's gates collapsed.

2. East China Sea Conflict (1470 AD)
Centuries later, in the East China Sea, the border between China and Japan was in turmoil. A Ming Dynasty ship sailing to the Majapahit Empire in the Indonesian archipelago—carrying the princess betrothed to be the wife of Majapahit's 4th King, King Hayam Wuruk—was struck by a storm and captured by pirates.
This news reached the World Government Fleet Admiral, Monkey D. Kong. Without hesitation, Kong immediately assigned two of his best officers, Admiral Sengoku and Vice Admiral Garp, to lead the fleet to rescue the princess from the hands of the vicious pirates.
Back in the present, on the Pangea Continent (City K), Earth's physical reality has been nearly completely destroyed by the egos of two powerful beings. Saitama and Garou have reached the absolute limits of their power.
"I just want to fight a worthy opponent," Saitama said, his face impassive but his eyes gleamed with a deep emptiness. "Being defeated every time I swing my fist, the opponent in front of me dies instantly... how boring."
"You are a worthy opponent for the God-Destroying Fist I've perfected!" roared Garou, his body enveloped in cosmic energy.
"Serious Series Fist: SERIOUS!!" shouted Saitama.
"Cosmic God-Destroying Fist!" Garou retorted.
Watching the energy capable of vaporizing solar systems collide, Blast panicked. "This is bad! Find a fulcrum! Find their positions! Help me move them both away from Earth!"
With the help of his allies, a giant vortex hole opened just as the two fists collided. BAAM! The explosion warped space and time, sending Saitama and Garou directly into Jupiter's orbit. There, the shockwave from their blows shattered Jupiter's moons into cosmic dust.
On Earth, Blast gasped for breath, aided by Hagoromo Otsutsuki (Rikudo Sennin), who intervened to stabilize the dimensional tear. "Thank you, Hagoromo. If this space hadn't stabilized, the Outer Gods would have entered our world. Those two fools fought without thinking about the consequences for Earth. No wonder Earth keeps spawning strange creatures from its belly... it's all because of humanity's destruction of nature. Disasters everywhere."
Despite the cosmos being shaken, life in Tokyo city went on in strange contrast. At Tokyo University, the fragrant aroma of cooking spices filled the special cooking classroom.
The three upper-class demons of the High School DxD faction—Rias Gremory, Sona Sitri, and Akeno Himejima—looked solemn in their aprons. Before them stood two chef trainees brought directly from a renowned Italian restaurant: Soma Yukihira and Erika.
Erika was no ordinary chef. She was the butler of the Red Dragon Queen, Rose Ryu Gu D Barselion. Although her combat power was low for a supernatural being, Erika possessed the legendary God's Tongue. She was an absolute master of nutrition, food manipulation, and poison antidotes.
[Mystical Cooking Training Menu] Goal: Please their husband, Jun Ryu. Identity: Jun Ryu is one of the Seven Primordial Devils. Power: Equivalent to Great Red's true form. Specialty: Food that enhances spiritual energy without the side effects of elemental poison.
"If you want to capture the heart of a Primordial Devil like Jun Ryu, your cooking can't just be delicious," Erika explained, tasting the sauce with the tip of her tongue. "Every drop of the ingredient must be able to imbue him with magical energy equal to Great Red's."
The arrival of Great Red at the University of Tokyo, now living under the alias of a handsome red-haired student, brings about major changes. Along with Rose Ryu Gu D, the two attend the invitation of the Hindu Trimurti, who are panicking over the threats of Madara, Kaguya, and Marisbury's SCABA system.
The supernatural world now stands at a very dangerous crossroads. Dark forces from the past, forbidden Chaldea science, and the cosmic destruction caused by Saita's battle Garou threatens to wipe out both humanity and supernatural beings altogether.
However, armed with the astronomical knowledge inherited from his parents, the Shinigami power of Uchiha Darman flowing through his destiny, and the united courage of the true dragons, Great Red and the Red Dragon Queen stand at the forefront. They step forward into the moonlit night, ready to face the coming multidimensional storm. They are no longer mere ancient myths; they are protectors, shields, and a new dawn for peace for all beings in the universe.
