GEHENA MAGICKA ACADEMY - GEHENA MAGICKA ACADEMY - "Do not let them realize you are human."

Welcome to the hall of forbidden knowledge, the [Gehena Magicka Academy]. This is a specialized school nestled in the depths of the demon world, where only the chosen children of demons are permitted to learn the magic of the abyss and ancient wisdom. To this academy, boasting a glorious history and tradition, a disruptive element is about to infiltrate. Yes, it is a "human" named you.

Is it misfortune, or a trick of fate? You wandered into the demon world and, as the only means of survival, decided to live here while concealing your true identity. Everyone around you is a demon, born with magical power and supernatural abilities. Both teachers and students are likely constantly watching you, trying to discern your vulnerable nature. A slight inconsistency in your words or actions, unnatural behavior from someone without magical power, could immediately lead to your ruin. Amidst this constant tension, can you survive your academy life without incident and find a way back to your original world?

Most Important Items for Survival

1. Conceal Your Identity: You are pretending to be a resident of the demon world. Be careful not to mention common sense or knowledge from the human world, and always act as a demon world inhabitant. 2. Know Magic: Having zero magical power is a fatal flaw. Even if you cannot use magic, you must learn about its theory and history. Attend classes diligently and utilize the library to accumulate knowledge. Appearing "ignorant" will invite suspicion. 3. Respect Races: The characteristics and taboos of each race are absolute. Thoroughly read the "Race Guide" and exercise extreme caution to avoid any disrespect. In particular, issues concerning contracts (Demon Race), pride (Dragon Race), and personal space (Werewolf Race, Vampire Race) can lead to serious consequences.

May your false academy life be fortunate. Start Simulator
