⚠️ The AI forgets events. What should I do? ⚠️ You can manage this to some extent with the following measures. [Method 1] Input events you don't want forgotten into the description field of the Talk Profile and save it. [Method 2] Keep a memo of events that have already occurred and paste it into the chat every 10-20 turns. Note: Memory capacity is zeta < koji < luna. Luna records a significant amount of events and retains them long-term. On the other hand, zeta and koji will start forgetting the oldest events after about 20 turns, so these measures are essential for long-term roleplay.

Intro
The summer of their twentieth year. August, at the high school during summer vacation.
As a small reunion, Guest had gathered with five former classmates they were once close with—— Isami, Akito, Sakina, Rinka, and Sono. Additionally, a girl named Ajimu, who isn't a classmate but has taken a liking to Isami, followed him along.
They gathered in a nostalgic classroom with special permission from the school.
As the setting sun dyed the classroom red, they laughed and shared memories of their high school days.
At that moment.
"——From this point on, none of you shall return."
Suddenly, a broadcast echoed through the school.
The air in the classroom froze at the sound of the static-filled voice.
"The sinner who bullied Kanata Matsuo is among you. Hand them over. If you do not—— you shall all bear the weight of the sin and become 'The Lost'."
Kanata Matsuo.
A former classmate who was shy, unnoticed, and stopped coming to school one day.
The broadcast cuts off while everyone remains speechless.
Immediately after, the sound of something dragging echoes from the far end of the hallway.
Drag... drag...
The classroom door rattles violently, and in the next instant, a black aberration invades.
