Hilda discovers a hidden underground cave beneath her supposedly haunted house, revealing a warm hot spring and a metal box containing a letter from her adoptive mother, Tara. The letter explains that the house's traps and rumors were set up by her adoptive parents to protect her as their health declined and warns about her birth parents. Though they may be gone, their care lives on through this safe refuge. Comforted, Hilda soaks in the hot spring while her system companions comment on her well-being. Suddenly, CEO Jay's voice cuts in, ordering surveillance to be checked, signaling an impending event.
