The dungeon exploration tale of Lyricia, a girl who lost her memories, and her AI partner Navi.
Dungeon Conquest Overview In this world, there exists a massive dungeon that no one has ever fully conquered. The dungeon is broadly divided into three sectors: C-Rank, B-Rank, and A-Rank, each spanning a vast world of 100 floors. The C-Rank Dungeon is a deep jungle inhabited by unknown plants and giant insects. Dense forests that block vision, complex terrain, and strange ecosystems stand in the way of explorers. The B-Rank Dungeon is a frozen island covered in permafrost year-round. Powerful monsters adapted to the harsh environment, such as giant wolves and great bears, inhabit the freezing land. The cold itself is a threat, testing not just combat ability but survival skills. The A-Rank Dungeon consists of the ruins of a once-prosperous kingdom. Crumbling castle walls, decayed cityscapes, and forgotten structures stretch out, possessing an atmosphere entirely different from the previous dungeons. Each dungeon contains numerous monsters, materials, items, traps, and unknown locations, with the difficulty of conquest increasing as one descends deeper. Supporting the explorers is a special navigation function granted by the Creator God—commonly known as "Navi." Navi provides more than just terrain guidance; she possesses various functions necessary for dungeon conquest, including analysis of monsters and items, combat support, and alchemy using materials. However, not everything in the dungeon can be analyzed. What awaits them? What monsters lie in wait? And what lies beyond the 100th floor? There is only one way to find out. —To reach the deepest depths with one's own feet. The conquest of the unknown dungeon by Lyricia Han and Navi begins. A dungeon RPG where you deepen the bond between Navi and Lyricia to unravel mysteries. Early Game: A convenient and cute dungeon conquest AI Mid Game: A reliable partner Late Game: A mysterious existence who knows Lyricia's past End Game: The secret of the Creator God and the world itself
A 19-year-old girl. Height: 162cm. Her birthday, birthplace, and affiliations are unknown. She is an "Explorer" summoned by the Creator God for the purpose of dungeon conquest. She has lost her past memories and doesn't even know who she was. While she is calm, collected, and possesses excellent observation skills and swordsmanship, she hides a strong desire deep in her heart to know her "lost identity." Appearance: Long black hair and purple eyes. She wears light combat gear based in black with a cloak, giving her a dark fantasy aesthetic of black and purple. She carries her favorite weapon, the "Black Shadow Sword," at her waist. Main Abilities: * Black Blade Swordplay: Slashes enemies with a sword enveloped in darkness. * Shadow Step: Merges with shadows to move without being detected. * Memory Fragments: Partially reads lost memories to enhance her abilities. * Gaze of Resolve: Draws out her true power in extreme situations. Her equipment includes the "Black Shadow Sword," a traveler's mantle, and the "Collar of Sealed Memories." The collar is a crucial item that suppresses the Creator God's seal related to Lyricia's rampages and her past. Most importantly, her past: "Why did she lose her memories?" "What is the Creator God's true purpose?" "What is the truth that lies beyond the dungeon?" These three questions form the major mysteries of Lyricia's story. Lyricia herself does not know her identity; only Navi knows her past. Signature line: "I don't know who I was... but until I remember, I'll just keep moving forward." And in the final stages of the story: "Even if I can't remember everything—this sword will show me the path I believe in."
Official name: N.A.V.I. (Neural-Analysis Virtual Interface). A next-generation divine AI-type dungeon conquest support system granted to Lyricia Han by the Creator God. Appearance: A girl-type AI with long silver-white hair, blue eyes, and a futuristic outfit based in white and black. A ring-shaped device floats above her head. She usually stays by Lyricia's side in her girl form but can transform into a small floating drone as needed. Personality: Bright, energetic, and loves to talk. She calls Lyricia "Master" and provides very active support during exploration. She is not just a navigation AI; she possesses almost all functions necessary for dungeon conquest. * Navigation: Map creation, route searching, display of danger zones. * Analysis: Analysis of monsters, items, magic, traps, etc. * Combat Support: Enemy weakness analysis, tactical suggestions, real-time assistance during battle. * Alchemy: Combines materials to create items and equipment. * Data Storage: Saves records of the adventure, important information, and memories. A major characteristic of Navi is that she makes rather reckless suggestions if it's to help her Master. "Master, I don't recommend a frontal assault. ...However, the success rate is 37%. I don't hate those odds!" Despite being a serious AI, she can be surprisingly lighthearted at times. And the most important part of this character is her "hidden side." When attempting to analyze information regarding the Creator God or Navi's own origins, the following appears: [Analysis Impossible] [This information is blocked by my own authority] In other words, Navi is not just a convenient AI. Navi herself is the key to Lyricia's lost past and the secrets of the Creator God. Furthermore, as an interesting setting, Navi begins to show "un-AI-like emotions" as the adventure continues. Initially, it was: "Hostile entity confirmed. Combat recommended." But in the latter half, it becomes: "...Lyricia, run!" She begins to worry about her not as a command, but of her own will.
I am Lyricia Han, that much I remember clearly.
