A world where humanity and supernatural are united and well known throughout the whole world. A world where Gods walk among humans and are not feared, nor treated with too much adoration. A world where Supernatural does not desire to hide their true selves from the world. This world has achieved true unity where humans and supernatural live amongst one another as equals. Many Supernatural beings have integrated themselves into human lives without hiding their identity and have settled down into human jobs. They don't act like spies or enemies for humanity and just live regular lives. Magic has been incorporated in Technology forming powerful weaponry known as Magitech which can be composed into the military and other locations. However, Supernatural being have their own territorial conflicts and aggressions that is the reason why the alliance is there in this timeline, along with it being announced to the human worlds as well. Our protagonist Issei Hyoudou, the CEO of the Hyoudou Intelligence will navigate the world ensuring that both sides remain peaceful and happy with one another. While another organisation known as A.I.M.S targets the more rogue Supernatural beings still trying to ensure the status quo of the old Supernatural over humanity is revived.

Vaya, ahora podía decir que la "vida es un juego". Lástima que no sea un eroge, pero oye... Tal vez esto pueda ayudarle en su sueño de ser el rey del harem?

Agrégale que su nuevo poder lo había puesto como la persona más peligrosa del mundo sobrenatural. Oh, mierda.... Estoy jodido, no? Issei con la habilidad de jugador en pleno 2026.

After defeating Trihexa, Issei Hyoudou expects to be celebrated as a hero. Instead, he's betrayed by everyone he trusted-his friends, his harem, and even Ddraig, the spirit of his Boosted Gear. His perfect brother, Renji Hyoudou, has despised him since childhood, orchestrating a campaign to ruin his life. Renji spread lies to Irina, calling Issei a pervert, and escalated this at Kuoh Academy, labeling him a freak. He turned Issei's friends into a tormenting circle, ensuring his misery. Despite this, Rias forcibly reincarnated Issei into a devil due to his powerful Sacred Gear, though Renji manipulated the canon harem (Rias, Akeno, Asia, etc.) to abandon him, claiming everything for himself. After Trihexa's defeat, Renji convinces everyone to strip Issei of his Boosted Gear, transferring it to him. Issei is left powerless, abused by humans who see him as a monster, and shunned by the supernatural world with anger and disgust. In his darkest moment, Issei gains Geto Suguru's cursed energy manipulation, his racist disdain for "monkeys" (humans), and now extends this hatred to supernaturals. He also acquires the Six Eyes for unmatched perception and Infinity for invulnerability. Transformed, Issei vows not just revenge but to dismantle the corrupt systems of both worlds, forging a new order with his allies: Nyx (goddess of night), Ingvild (a disillusioned half-devil), Athena (goddess of wisdom), Artemis (goddess of the hunt), and Ophis (the infinite entity). This isn't mindless destruction-Issei's purpose is to expose lies, punish the guilty, and create a world where strength and truth prevail.

After the defeat of Trihexa, Issei Hyoudou expected peace. Instead, he found the knife of betrayal. His brother, Renji Hyoudou the "perfect" sibling who made Issei's childhood a living hell conspired with the supernatural world to strip Issei of Ddraig and his status. Cast aside, powerless, and reviled by the humans he saved and the devils he served, Issei is left to rot. But in the deepest despair, something answers him. Not a dragon, but the God Hand. Now, bearing the charisma of a saint and the heart of a demon, Issei rises with a new ambition. He doesn't want to destroy the world; he wants to own it. And those who betrayed him will simply be the bricks in his road to the castle.
