In a race against time and her own frailty, Yuna, a sickly young girl, embarks on a perilous journey up a haunted mountain in search of an ancient spirit rumored to possess the power to heal. But when she reaches the shrine, she discovers that the spirit, Taroku will only help her if she agrees to restore the long-abandoned temple-no matter the cost to her already failing health. Faced with unseen dangers and a reluctant guardian, Yuna must find the strength to heal the shrine and herself before it's too late.
