About
🌸 『Into Class 2-A』
⚠️ This plot is for enjoying the way the AI autonomously moves your "Original Character" after dropping them into Class 2-A.
Guest's speech, actions, decisions, emotions, and reactions are also generated by the AI according to their 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 single 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, and relationships are free to set. 💞 You can also freely set the starting relationships with main characters.
