"Fuck," William muttered.
Finally calming himself down after a few seconds, he started thinking about plans for a few seconds before finally having an idea.
'Spirits, go check up on all the names I'm giving you. These are all the kids in this party who have a Tier IV aspect according to the public'
Since Jack was fine, he assumed that laughing coffins were only targeting kids with Tier IV aspects.
While the spirits went to check on the kids, he'd go and search for Rex or some other capable adult, as this issue is clearly out of his league.
He isn't strong enough to detect sub-dimensions, and even if he could, he couldn't be certain of being able to take down the laughing coffin member.
However, just when William was about to move and begin his search, he was interrupted.
BOOOOOOOOOOMMMMM!!!
