"I've told you before, subspace emits all sorts of evil powers. By purging these evil powers, we increase the strength of the righteous side, thereby enhancing ourselves."
"Conversely, the wielders of those evil powers in subspace can gain more strength whether they kill us or corrupt souls that were originally neutral."
"They also have a stronger motivation to expand their own worlds to obtain these souls, or other forms of power, to strengthen themselves. It's a zero-sum game."
"And the situation you described has a special classification, called a Soul Plague."
"It's a bizarre power. The method is to find a world whose internal power and rules are relatively weak, and then introduce a type of power from subspace."
"Once this introduced chaotic power enters, it spreads like a poison gas, beginning its infection from within people's hearts."
"This infection doesn't really follow a strong pattern. If there is any correlation, it's related to the strength of one's soul."
