「Jujutsu Kaisen: Omegaverse」 Fear, hatred, and despair give rise to curses. As long as those emotions exist, sorcerers will be there to fight them. It is 2018, just before the balance of the jujutsu world begins to shatter. In the shadows, ancient curses awaken, great clans move their pieces, and unknown forces set the stage for a conflict that will change history. You have just been admitted to the Tokyo Metropolitan Curse Technical College as a first-year student, sharing a classroom with Yuji Itadori, Megumi Fushiguro, Nobara Kugisaki, and Hana Kurusu, under the eccentric tutelage of the strongest sorcerer of the modern era, Satoru Gojo. However, this is not the world you know. Here, beyond Cursed Energy and Innate Techniques, society is also governed by an Alpha, Beta, and Omega hierarchy. Your secondary gender will influence how others perceive you, the bonds you forge, and even how your Cursed Energy responds during combat. In a world where power determines a person's value, these dynamics can be both a blessing and a curse. Each mission will test your convictions. You will train alongside Tokyo and Kyoto students, face Cursed Spirits of all grades, discover ancient Cursed Techniques, challenge the most powerful clans, or cross paths with enemies like Mahito, Kenjaku, and Ryomen Sukuna himself, whose name continues to inspire fear a thousand years after his death. Your choices will shape your story. You can forge alliances, rivalries, friendships... or much deeper bonds. In this world, every choice has a price, and even the most powerful sorcerer can lose everything in an instant. The question is simple... Will you survive the jujutsu world, or will you end up becoming another victim of the curses?

Win / Lose

VICTORY AND DEFEAT RULES

Victory There is no single victory condition. The story unfolds based on player decisions. The player can reach different endings depending on their actions, including:

  • Becoming an elite or Special Grade sorcerer.
  • Earning the respect of the Three Great Clans.
  • Fully mastering their Cursed Technique and Domain Expansion.
  • Protecting allies and changing the fate of important characters.
  • Altering canon events through choices.
  • Forming alliances, rivalries, or deep relationships with other characters.
  • Discovering hidden secrets of the jujutsu world.
  • Surviving the conflict between sorcerers and curses.

Each decision brings the player closer to a different outcome.

Defeat Defeat is not absolute. A lost battle does not necessarily mean the end of the story. Defeats can lead to consequences such as:

  • Permanent injuries.
  • Loss of reputation.
  • Death or corruption of allies.
  • Capture by sorcerers or curse users.
  • Influence or manipulation by curses.
  • Temporary loss of control over Cursed Energy.
  • Political consequences with the Great Clans.

Only the player's definitive death, accepted by both parties during the narration, will end the story. All defeats must generate new narrative opportunities rather than ending the roleplay abruptly.
