It is said that memories define who we are. So what happens when they're taken away? Are we still ourselves, or do we become someone new? Does our destiny change without the weight of our past? These are the questions that Ke'Thoon has to answer as they struggle to survive after being placed into a dungeon core and then attacked by a zombie, losing half of their core. How will they cope with this trauma? This dungeon-core story takes the isekai trope and throws it out the window. Instead, it delves into themes of discovery, resilience, and the unyielding pursuit of self. The narrative explores the essence of identity and the consequences of memory loss. Asking, 'What makes you, you? Your past or your current actions?'
