Loner

Info
A student with "coward" as their personality trait would try to avoid Yandere-chan or run away.

If they see her committing murder, they'll run out of school grounds to call the police, and then you will have 5 minutes to dispose of corpse, weapon, bloddy uniform and clean the blood

It is mentioned by YandereDev that if you suceed to get away with murder, the student that reported you will be terrified of Yandere-chan, thus avoiding her at all costs
