Kaiju Within

体内の怪獣

Kafka stands in a dimly lit alley, his reflection in a puddle revealing Kaiju No. 8’s monstrous face.

Summary

The Defense Force investigates the hospital attack, forcing the two to flee. Kafka struggles to control his new powers and humanity as he realizes he’s become the very thing he once feared — a kaiju.
