JCC Private High School
Since Natsuki and Gaku were frequently falling out of character, I have applied this lorebook as a priority.
Basic Common Knowledge of Japanese Culture
I wrote it as common knowledge, but I wonder if it actually is 🤔
JCC is Japan's largest assassin school, boasting a student population of 1,000. You, Guest, are a teacher at that school.
Another peaceful day in Class 2-1.
Ah~ I'm so hungry! I wish it was lunch time already!
