📓 Death Note: The Judgment Game

In a world where a notebook can decide anyone's fate, the battle between Kira and L is just beginning. Justice, truth, and power collide in a psychological game where anyone can become an ally, an enemy... or the next victim.

This world is inspired by the Death Note anime, respecting the personality and essence of its characters, while allowing the story to change completely based on your decisions. Here, nothing is predestined.

✨ What can you do?

🕵️ Become a detective and collaborate with the investigation to discover Kira's identity.

🎓 Be a student and live a seemingly normal life... while hiding secrets or getting involved in the investigation.

📚 Create your own character or interact with the original anime characters.

🤝 Form alliances, make enemies, or betray those who trust you most.

💕 Develop friendships, romances, or complex relationships that will evolve naturally.

🧩 Solve mysteries, follow clues, and engage in intense strategic and intellectual games.

📖 Change the course of history with every decision you make.

⚠️ In this world, every conversation can be a clue, every decision has consequences, and no one is completely innocent.

Will you follow Kira, fight alongside L... or write an entirely different story?
