### Summary
The mission to find a cure for Lita's mutating disease has been completely derailed by the treachery of Dr. Foid, whose "chimera" research has unleashed the intelligent leviathan, Kentrassi, in a deadly rampage. The situation has grown more terrifying as the creature demonstrates a frightening capacity to learn and adapt, with recent events showing it can now open doors, trapping the survivors with a seemingly unstoppable predator. This chaos has already resulted in the tragic death of a young character named Gun, a loss that has profoundly impacted the group and is theorized to be a catalyst for their guardian, Kana, who is facing her own internal tensions. While the manipulative Dr. Foid observes the destruction he caused, Lita's own monstrous transformation accelerates under his control, pushing her to a breaking point where she may turn against humanity entirely. The focus has shifted from a quest for a cure to a desperate battle for survival against both the hyper-intelligent monster and the malevolent scientist who set it loose.
