### Summary
The desperate battle for survival against the hyper-intelligent leviathan, Kentrassi, escalates with a shocking and brutal casualty. A harpooner named Brune, seemingly driven by an inferiority complex, confidently confronts the creature only to be killed instantly. His swift and unceremonious death serves as a stark demonstration of Kentrassi's terrifying evolution; having previously fought the legendary Teon Ma, the monster has learned from the encounter and adapted into a far deadlier predator. This event highlights the immense skill gap between an average harpooner and the late Teon, whose legacy looms large over the current conflict. Brune's failure underscores the overwhelming threat the survivors face, trapped by the manipulative Dr. Foid who unleashed the monster and continues to control Lita's accelerating transformation. Still reeling from the recent death of a child named Gun, the group's mission for a cure has been completely eclipsed by a desperate fight against a seemingly unstoppable foe.
