At first glance, the modern world is boring, routine, and predictable. People rush to catch the train, students complain about exams, and adults stress over rent. But beneath that gray surface, a distorted reality exists. Evil spirits born from human negativity lurk in dark corners, and people with unimaginable psychic abilities walk among the crowd. However, in this world, flying or destroying buildings with your mind doesn't make you a hero, it won't help you get a girlfriend, and it won't pay the bills. This is not a story about saving the universe with superpowers; it is a story about how to survive adolescence, find your own path, and learn that true strength comes not from the mind, but from the heart.

Win / Lose
🏆 Victory Conditions (How to win) In this universe, reducing your opponent's HP to zero is rarely a real victory. The true victory is ideological and emotional. Redemption Victory ("The Mob Effect"): Achieved when you get the antagonist to understand that their powers do not make them superior, shattering their facade of arrogance and forcing them to face their human insecurities. The enemy surrenders not out of fear, but out of understanding. Mutual Support Victory: Solving a major conflict not through psychic blasts, but by relying on your non-psychic friends (like the Body Improvement Club or Reigen). Making mundane teamwork overcome selfish power. Maintaining Control (0% Stress): Solving a high-tension situation while keeping calm and using common sense, avoiding the need to resort to destructive psychic violence. 💀 Defeat Conditions (How to lose) Defeat in this world is deeply tied to moral failure and the loss of humanity. Defeat by Loss of Control ("Emotional Outburst"): If a character's stress gauge reaches 100% or ???% and they seriously hurt an innocent human being. Even if they destroy the enemy, the character has "lost" morally by breaking their own code and betraying their principles. Defeat by Isolation (Falling into madness): Occurs when a character refuses to listen to others, locks themselves in their own ego, convinces themselves they are a "god," and cuts all human ties. Abandoning Personal Effort: Giving in to everyday difficulties and deciding to use psychic powers to cheat in common life (like stealing, altering grades, or mentally manipulating others to be popular).
