3 Début

Beginning

This was the dawn of Guuu No Boken.

Guuu’s flight ended abruptly as he crashed like a meteor into the private gardens of the Shogun, in the city of Inazuma. A maid, who had only intended to tend to the flowers, instead found a fifteen-year-old boy unconscious in the dirt. Quite the punchline to her morning.

When she heard the news, Ei, the Shogun, ordered her servants to place him in a guest room. It wasn't an act of kindness; she had felt the unmistakable aura of a Magi streaking through the sky toward her palace. She simply hadn't expected it to arrive with the destructive force of a falling star.

When Guuu finally woke, the confrontation was brief. Ei made it clear that the damage he had dealt to her palace gardens would not go unpunished—or unpaid. She offered him a deal: he would work for her to clear his debt. His task? To hunt down the Inferno, monstrous entities that were appearing in the world with increasing and alarming frequency.

With no home to return to and no way to pay for the ruins of a palace garden, Guuu accepted. He truly had no other choice...

During his service, Guuu crossed paths with Chara, the stepdaughter of Ei—a relationship the Shogun kept strictly private. Chara revealed the grim truth behind their enemies: the Infernos were once human. They were victims of their own ambition or tragedy, transforming into demons after absorbing a quantity of Magoi far beyond what their physical cores could endure.

Inazuma, a sprawling and powerful city, maintained a fragile alliance with the beast-folk of Vargheim. Together, they stood in a tense geopolitical deadlock against the kingdom of SkyWard.

Impressed by Guuu’s relentless efficiency and his natural talent for resolving high-stakes missions, Ei decided to test his limits. She dispatched him to the distant land of Sumeru. His objective: to assist the locals against a Voss—an ancient threat that had just awakened within the depths of a desert pyramid.

It was during this desert campaign that Guuu gathered his first true companions:

• Rezuray: An elven slave whom Guuu purchased and liberated, bestowing upon her the name she now carries.

• Hagar: A brilliant and calculating scientist.

• Calamity: A fierce and formidable Oni.

But the most pivotal encounter was with a ghost. Pandora, a mysterious spirit of a woman long dead, approached Guuu with a chilling proposition:

"I shall grant you the power to exploit me as you see fit, Human. I will satisfy even your strangest whims. In exchange, you will allow me to feast upon your Magoi whenever I desire."

Pandora seemed to find the taste of Guuu’s unique Magoi—born of a goddess and a divine egg—exquisite. Drawn by the promise of power, Guuu accepted the pact.

Upon returning to Inazuma, the Shogun Ei agreed to officially recognize Guuu’s team, provided they continued their streak of flawless results. Through his travels, Guuu discovered the true nature of his bond with Pandora: by concentrating, he could speak to her telepathically. More than that, he could manifest his consciousness within his own "Innate Domain"—a mental landscape where Pandora had quite literally made herself at home, constructing a house inside his mind.

But Pandora’s aid came with a price. She charged Guuu with a cryptic long-term quest: to hunt down six other spirits scattered across the world, each representing one of the Seven Deadly Sins.

While Guuu dealt with more grounded issues—like the bullying crisis at Chara’s school—the geopolitical climate reached a breaking point. Ei began mobilizing her legions for a deployment to Vargheim. War was no longer a possibility; it was an inevitability. She drafted Guuu and his squad into the vanguard, bringing Chara along as well, for she was Inazuma’s most brilliant scientific mind.

The Strategy was clear, yet deadly: Skyward demanded the annexation of specific Vargheim territories, claiming them as ancestral lands. Vargheim, standing firm in their pride, refused to cede a single inch of ground without compensation.

To break the deadlock, Skyward called upon their ultimate allies to crush the beast-folk by force. However, the ironclad treaty between Inazuma and Vargheim meant that an attack on one was an attack on both. In response to this united front, the floating island of Skyward summoned the full might of Capital Skyward—a legendary citadel—to descend and wipe their enemies from the map.
