Mirai's journey escorting Kakashi and Guy takes an unexpected turn when their route is cut off by a massive landslide. While stopped at a village, Mirai meets Tatsumi, a young girl whose mother has died. She reveals to Mirai that she's in this particular village because there's a hot spring nearby that can bring the dead back to life. Mirai decides to join Tatsumi for a chance to meet her father, whom she only knows from the memories of others. What she finds is anything but the miracle hot spring she was hoping for--instead, she discovers the very cult that killed her father!
