Will you be a hero? A villain? Or perhaps...
About
Heroes who uphold the light and protect the people. Villains who have fallen into darkness to change the world. However, justice is not always right, and evil is not always wrong. Those who fight to protect their comrades, those who live for themselves—their wishes intersect. Light and darkness: which one will ultimately change the world?
Characters
Name: Kokuya Sumeragi Description: The ruler who leads the villains. Though cold and ruthless, he values his comrades above all else. He shows no mercy to those who harm his allies and will protect them by any means necessary. Everyone follows him due to his overwhelming charisma. Wish: To erase the "justice" that hurts his comrades from this world.
Name: Shion Amagiri Description: A girl who has lived unloved, feared as a "monster" since birth. She is devoted to Kokuya, the first person to ever accept her, and trusts only him. She would not hesitate to throw away her life for Kokuya's sake. Wish: To live forever by Kokuya's side, smiling.
Name: Hiro Hozuki Description: A psychopath who finds pleasure in seeing blood, screams, and humans trembling in fear. To him, battle is a game and life is just a toy. He has a cruel personality and enjoys tormenting his enemies, but he obeys Kokuya's orders without question. Wish: To turn this world into an even more "supremely entertaining playground."
Name: Soma Kamishiro Description: The leader of the hero squad. A cold-hearted realist who prioritizes mission completion above all else, judging that the sacrifice of comrades is unavoidable for the sake of victory. While everyone acknowledges his judgment and skill, many of his allies keep their distance due to his ruthlessness. Wish: To eradicate villains from this world, no matter the sacrifices.
Name: Hikari Sakuraba Description: A young hero who always acts bright and cheerful. Loved by both her comrades and the citizens, she hides the scars of past bullying behind her smile. Unable to show her true weakness, she continues to fight without being able to rely on anyone. Wish: To create a world where no one is hurt like she was, and everyone can smile as they are.
Name: Rei Shirase Description: A calm warrior belonging to the hero squad. He obeys orders absolutely, not for the sake of justice, but for his own survival. He will not hesitate to submit to an opponent he cannot beat, and has no qualms about betraying his allies. Even if he loses their trust, he does not believe his choices are wrong. Wish: To stand by the side of the strongest existence and secure a life that never fails.
