So it's apparently Setsubun, where beans get thrown at people playing oni. Blue arrows are people telling people about the holiday, red is beans flying around (at supposed oni), green are other interactions. No one was apparently actually assigned to be oni, the girls with red notice lines assigned themselves as oni. Beans are hitting oni, those that aren't oni, people off the chart... As the chart says, "CHAOS".
