Chise and Teto return to the Wasteland of Nothingness with heavy hearts after being forced to say goodbye to Selene. To curb their loneliness, the pair begin to build a new home while lending their assistance to Prince Gyunton to break up a secret network of slavers in Gald. However, a strange drain on Chise’s mana restoration project in the Wasteland of Nothingness puts all this on hold, and they find a precursor ruin practically underfoot! Homesteading will have to wait as adventure calls, and somewhere in those sunken vaults is an enigmatic new friend in need of mending. Can Chise rise to the task or is it impossible—even for her?!
