Nagisa is a social coward. Similarly to the sleuth, he is affected by atmosphere. In high atmosphere (or medium), Nagisa will run to the nearest group and call the cops. In low atmosphere or having witnessed the murder of 2 people before he can reach the destination, he will pray for safety and promise not to call the cops. He will talk to the murderer if the school atmosphere was low, but will lower your reputation if other students notice his fear
