Upon learning of the Bliss Society's plan, Lumian's immediate assumption was that Susanna had made a crucial mistake.

What lay sealed within him wasn't just corruption at an angelic level, but an actual Angel!

While there was still a possibility of explosion, Susanna and the other heretics believed they could manage the situation.
