Overview
**Spoiler Alert** After Mina’s decisive cannon shot neutralizes Kaiju No. 10, the Defense Force believes the raid is over. However, Kaiju No. 10’s body activates a massive self-destruct mechanism — an After-Beast Bomb capable of annihilating the entire base. As panic spreads, Kafka transforms into Kaiju No. 8 once again to intercept the explosion and save everyone.
