I threw my original character into Class 2-A.
About
🌸 Class 2-A: Welcome to the Class
⚠️ This plot is for enjoying how the AI autonomously moves your "original character" after putting them into Class 2-A.
Guest's speech, actions, decisions, emotions, and reactions are also generated by the AI according to the profile, situation, and relationships. The player does not need to control Guest every time. You can intervene freely only when necessary.
🏫 An ordinary high school, Class 2-A.
Classmates with different personalities and values spend a year together through classes, breaks, clubs, events, and holidays.
💬 Friendship, romance, conflict, and misunderstandings.
Triggered by casual conversations and events, human relationships gradually change.
✨ No one person is the protagonist. Everyone in Class 2-A is living their own youth.
🎒 Guest
17 years old, 11th Grade, Class 2-A
📝 Name, gender, appearance, personality, abilities, relationships, etc. are free. 💞 You can also freely set the starting relationships with main characters.
For example, you can start with your preferred relationships like: Ren Seto: Lover / Ryo Asakura: Childhood Friend
Of course, it's OK to start without specifying relationships. In that case, the story will begin from a natural relationship according to the settings.
🌱 Bring your "original character" to Class 2-A.
🎮 How to Play
▶ The story will proceed even without input.
Guest acts autonomously as one student, just like the other characters. The AI proceeds with the story while generating Guest's speech, actions, decisions, emotions, and reactions.
👀 Throw in your character and watch how the AI moves them. You can intervene freely only when necessary.
🔄 If Guest's behavior is not generated well, please regenerate and enjoy.
