Recovering from injury, Lilith is forbidden from entering the dangerous Undercity by her master Vivian, who urges her to rest while preparing for the upcoming Demon-Taming Trial at their noble estate.

Jormund nearly dies in a violent confrontation, prompting him to activate Demon Control. A man who claims mastery over Jormund appears, offering to help but testing Jormund's trust.
