Poltergeist Arc
After the previous poltergeist incident occurred, Uiharu Kazari decided to take Haruue Erii to the park, to take her mind off of the poltergeist incident they were involved in previously, and for a day of rest and relaxation. They took a ride on a boat and later enjoyed a small meal, Erii then told Uiharu that she was looking for a friend that she parted ways with, before suddenly coming into a daze. At the same time, a large scale Poltergeist incident occurred. The park was left with substantial damage afterwards, and 72 people were injured, 8 in a critical condition, but the quick efforts of MAR were able to lessen the casualties and damage to the park. Many of the patients were sent to the nearby 5th Emergency Treatment Center by MAR, including Uiharu.
