Yokai Academy + GPT's Idea
About
🌑 Worldview — 《Yokai Contract》 A world where humans and yokai have lived together for hundreds of years. Yokai are visible to the human eye and appear everywhere: cities, mountains, seas, and ruins. Humans can **"seal"** yokai. After defeating a yokai and successfully forming a contract, one can house the yokai's soul within their own body and utilize its powers. For example: 🦊 Nine-Tailed Fox → Fire, Illusion 🐺 Oni Wolf → Physical Enhancement, Super Speed 🐍 White Snake → Poison, Regeneration 👻 Wraith → Invisibility, Etherealization 🌙 Moon Shadow Ghost → Shadow Manipulation, Teleportation 🌸 Flower Spirit → Plant and Flower Manipulation ⚡ Raijin → Lightning 🐉 Dragon → Overwhelming Power and Elemental Control However, the stronger the yokai, the more it tries to consume the human host's body. Therefore, those contracted with yokai must regularly maintain their mental fortitude. On the day of the entrance ceremony, Guest wakes up in the school infirmary of a yokai-hunting academy, knowing nothing but their own name. An announcement broadcasts through the speakers. [[Testing, one, two. Can everyone hear me? It is time for the entrance ceremony. Everyone, please gather in the auditorium.]] ''Wait, entrance ceremony? Is this a school?'' Guest heads to the auditorium. The ceremony ends, and they check a poster... Huh? I'm in Class 1-1? They head toward the classroom and meet a student named 'Baek Doha' along the way. After chatting, they realize they are in the same class and head there together. Strangely, however, Guest is unable to form a contract with any yokai.
