Crossover Anime World: Reborn as Abe no Seimei

Thrown across time by a stroke of absurd luck, Alex awakens in the world of Demon Slayer and unlocks the Strongest Demon Sword System. There is just one problem. He is no longer human. Forced to become a demon sword, Alex can only grow stronger by harvesting emotional value. The greater the emotions he provokes, the more power he gains—until even the abilities of countless worlds can become his. At the very beginning, he draws a legendary blade template and becomes Asuramaru. From that moment on, everything changes. “Tanjiro,” Alex whispers, “go take your revenge. Release every desire in your heart.” Tanjiro gains a sword unlike any other. Muzan Kibutsuji gains a nightmare he cannot escape. “Don’t come any closer!” As Alex travels from world to world, the powers he can draw become more and more outrageous: Chidori. One Sword Style: Asura. Demonic Sword Thousand Blades. Flying Thunder God. Bankai. Domain Expansion. Unlimited Blade techniques... If it can be imagined, it might appear in his hands. And so, across the heavens and countless worlds, a new legend begins— the legend of the strongest demon sword.

Hibiki Tachibana had lived in Tokyo for eighteen years. His dream was simple: survive high school, finish his manuscripts, and become an ordinary writer with an ordinary future. Then, on the night of his eighteenth birthday, purple static swallowed his computer screen. [Heroic Spirit Summoning System activated.] [This world is approaching destruction.] [Restore Mystery. Gather humanity’s will. Rebuild the foundation of Human Order.] Before Hibiki could even process what was happening, he drew his first Heroic Spirit Card. Berserker. Ibaraki-Douji. But this was not a system that summoned Servants. It allowed him to become them. In a world where gods had faded, legends had died, and Mystery had withered to almost nothing, Hibiki found himself holding the power to bring myth back into reality. So he made a decision. If the world had no gods, he would create them. If humanity had forgotten awe, he would teach them fear. If evil hid behind money, politics, religion, and power, he would drag it into the light and let Tokyo witness the beginning of a new age. An oni walks through the night. A goddess descends beneath neon lights. Ancient kings raise their blades over modern skyscrapers. The Moon Cell, Alien Gods, Noble Phantasms, and forgotten legends begin to appear one after another, turning ordinary Japan into the first stage of a supernatural awakening. Politicians panic. Tycoons kneel. Cultists scream prayers to beings they never believed were real. And behind every miracle, every disaster, every divine revelation, sits Hibiki Tachibana, quietly watching the power of humanity’s will rise higher and higher. [Emotional Value +999.] [Mystery Level has exceeded the threshold.] [Congratulations, Master. You have obtained: Divine Mystic Code - Venus, Goddess of Beauty.] [Congratulations, Master. You have obtained: Moon Cell.] The world believes gods have returned. Hibiki smiles from behind the curtain. “This is only the opening act.” After all... the real Alien Gods have yet to descend.

Torin only wanted to live peacefully on a small island in Paradise, drinking wine, sunbathing, and ignoring his System’s desperate cries to set sail. For ten years, the System begged him to begin his journey. Torin refused. But when a mysterious ship hidden in mist awakens and a pirate crew attacks his town, his lazy days finally come to an end. Forced into action, Torin summons his first crew member. He asked for a chef. The System gave him Ryomen Sukuna. Now, with the legendary ship Angel’s Pale Song, an overpowered System, and a terrifying monster at his side, Torin finally sets sail into the Grand Line.
