Hurt has spent years pursuing knowledge and mastery while his childhood friend Hibana drifted away, content in her simple life among flowers. When the village's coming-of-age ceremony approaches, Hurt sees a chance to reconnect, urging her to flee and choose her own path. She refuses to listen, and his words fall flat between them. Then everything shifts. A catastrophic event shatters their small world and forces both into circumstances neither could have predicted. Suddenly thrown together again, they find themselves embarking on an unexpected journey through the sprawling depths of the World Tree, a massive structure that holds secrets and dangers neither is truly prepared to face. What begins as a survival situation becomes something more complicated: a chance to understand each other after years of separation. As they navigate supernatural threats and uncover mysteries woven into the World Tree itself, their connection deepens in ways neither anticipated. Adventure and danger mount with every step, but so does something neither can quite name.
