Healing Remedy

Exploration Stage: Shooting Star Cabaret
From: Mr. Black
Description: These scoundrels claim that there's no connection between them, but I see right through their lies. We'll discover in which brawl they got hurt. I've been informed that each of them purchased some sea buckthorn oil in the pharmacy. Does it promote wound healing? Let's get the oil and study it!
Completed: You brought some sea buckthorn oil. The instructions say that it contributes to the healing of burns. So it turns out that all these men in the Cabaret have burns on their faces!
