Not Zach's Problem

Zach didn't waste any time. As soon as the club members gathered, he started sharing with them his plans.

"As our name suggests, this club is about researching and exterminating the Underworld. We shall reach extermination through understanding. Thus, research comes first. We have to understand underworld energy and figure out weapons that work against it. 

"Right now, we have Julius' Mannequin, which is effective against the Underworld since it also uses underworld energy. But it will lose out against enemies stronger than it. My angel also possesses properties that work against the underworld energy to a certain degree.

"The problem is that neither of those are applicable to the rest of the tools in our arsenal. We have to learn more about underworld energy. That's why our first task is to gather and study samples from the forest."
