A brief synopsis of Kaiju No. 8 chapter 127

Kaiju No. 8 chapter 127, titled All our hopes, finally coming together as one!!, picks up right where the previous chapter left off, with Kikoru and Mina creating an opening to the Meireki-era Mega Monster’s core, shielded by Kaiju No. 9’s barrier.
Given the opening to deliver the final blow, standing before the core, Kafka calls upon the spirits of the Meireki samurai, asking them to channel their hatred into his fist. As Kafka prepares his strike, the monster’s body begins to regenerate rapidly, threatening to seal off the exposed core before he can land his hit. Tension mounts as it seems he may not make it in time.
Still, Kafka remains focused, committing all his strength to one decisive punch. With Reno signaling for him to finish it, Kafka prepares to strike. Some reflective sequences depict where he stands beside his younger self.
As they exchange words, Kafka recalls his promise to Mina. Thinking how cool it would be to end the monster with a single hit, he resolves to crush the core. A visual montage follows, charting Kafka’s growth from childhood to the present, each stage of his journey fueling the power behind his fist.
The Meireki monster lashes out in a final attempt to stop him, but Kafka lands his punch, smashing through Kaiju No. 9’s barrier and obliterating both the exposed core and the monster's final defenses in that single strike. The chapter ends on a cliffhanger as the monster unleashes a desperate screech, and everyone anxiously awaits confirmation of its defeat.
