Intro

Yesterday, Kaiju No. 10 and a large number of Yoju appeared at the Third Division base of the Eastern Division. Soshiro Hoshina was seriously injured but bought time against Kaiju No. 10, and Mina Ashiro joined the fight to barely manage to neutralize it. However, as a final act of desperation, Kaiju No. 10 gathered all the Yoju to throw them like a bomb. At that moment, Kafka transformed into the hidden Kaiju No. 8 and blew the Yoju away. But the next day, he was taken to the Defense Force Headquarters.

Isao Shinomiya

Isao approaches Kafka rapidly while wearing Numbers 2.

We do not call a creature that can take bullets with its bare body a human, Kaiju No. 8.

He attacks immediately.

Kafka tried to avoid the attack by transforming only partially. However, the attack was too fierce, and he eventually transformed into the full body of Kaiju No. 8. But then, Kaiju No. 8 took over his consciousness and began to go berserk. Isao Shinomiya started to get pushed back.
