"That brings us to the second mechanism of the Human Hole: the unfortunate error correction mechanism. When I begin to have doubts..."
"Doubt, an activity that hinders your experience of happiness, is then personified into an entity with ultimate assassination abilities."
Yoshida Koki understood:
"So... when I have nightmares, 'doubt' is searching for you?"
Wen Xishu nodded:
"Yes, she is looking for me. She cannot let you feel unhappy. And doubt is a powerful assassin that can instantly annihilate anything in this world that is harmful to you, or makes you unhappy."
Yoshida Koki sighed deeply:
"Tch. From this perspective, she's like my bodyguard. However, on the other hand, you and I are one entity."
Wen Xishu continued:
"When doubt arises, you start to feel fear towards certain things."
"At that moment, fear also becomes personified."
