With the golem situation resolved and the slums safe, it’s time for Zenos to take a well-earned vacation to the hot spring town of Flamme! When Krishna, Lily, and even Carmilla decide to tag along, Zenos realizes this trip is bound to be less relaxing than he hoped... Meanwhile, volunteer healers visit the slums to offer their aid. When they find no injured people in need of assistance, people in high places begin to suspect that something is amiss—and coincidentally, one of those individuals just so happens to be in Flamme on healing duty. Will Zenos be able to relax and stay in the shadows? Or will his brilliance be revealed, kick-starting a whole new adventure?
