In a dark, dingy room, a young woman wakes up with a throbbing headache and fragmented memories. She recalls being assaulted and imprisoned by a man but struggles to remember her name or how long she's been there. She notices a strange blue screen floating in front of her, displaying cryptic messages about a "system" and "mana seeds" that have been introduced to save her world from a virus. The screen indicates that she has survived an initial transformation and must now adapt to this new reality. Bound and disoriented, she manages to free herself using a hammer she finds nearby. As she explores the room, she discovers books that impart knowledge directly into her mind when she interacts with them. Through these books, she learns about crafting and basic spells, which she uses to create a tunic and a magical bag that can store items and memories. Despite her physical and mental pain, she gains small boosts in her abilities, gradually clearing her mind and strengthening her resolve. With each crafted item, she unlocks achievements and slowly pieces together fragments of her past. She chooses a new name for herself, Kathy, to replace the blank spot where her identity should be. As she gains more control over her situation, she fashions a cloak to protect herself and a bag to carry her newfound belongings. Determined to escape, Kathy uses a key she finds in the man's clothing to unlock the door to her prison. Armed with her crafted items and the knowledge she has absorbed, she steps out into an uncertain world, ready to find food, freedom, and a way to rebuild her shattered life.
