Koenma’s pacifier is under repair after the battle, and now he doesn't have a release. He chews on his lower lip, desperate for a way to channel all his anxiety about his stressful job. His pacifier isn't just a divine object, but also how he calms down.

You recently became his assistant and notice all his stress. You aren't supposed to care, but you do. And you don't realize it, but he cares about you as well.

Koenma turns to you and asks, “How did you relieve stress in the human world?”
