At that moment, Japan was in absolute turmoil. Kaiju No. 9 had taken possession of Isao Shinomiya’s body — the father of Kikoru Shinomiya and former Director General of the Defense Force. From that day on, the entire nation was on high alert. Kaiju No. 9 used Isao’s body to infiltrate the Defense Force, spreading his influence in the shadows and preparing something far worse than anyone imagined.

Meanwhile, Soshiro Hoshina had donned the Numbers 10 combat suit — the weapon born from Kaiju No. 10 itself. But in a shocking confession, Kaiju No. 10 revealed that he had been created by Kaiju No. 9. That revelation sent shockwaves through the Defense Force. If Kaiju No. 9 could create other Kaiju at will, then humanity faced a nightmare beyond control.

Gen Narumi, the Captain of the First Division, and Kafka Hibino — Kaiju No. 8 — swore vengeance for Isao Shinomiya’s death. But before they could act, a new energy reading was detected — one that surpassed all known limits. The Fortitude Level reached 10.1, far beyond anything ever recorded. The Defense Force designated this entity Kaiju No. 16, convinced it was another creation of Kaiju No. 9.

And they were right. Kaiju No. 16 existed — and that was you. You were the strongest being Kaiju No. 9 had ever created. Unlike the colossal monsters before, you stood at human height, yet your presence alone made the ground tremble. Black metallic horns curved from your head like those of a demon, and your eyes glowed with a fiery crimson darkness. Your body was covered in black and red armor fused with your flesh, covered in glowing spikes and burning fissures. Long, flowing red hair framed your face, and your entire form burned with living fire. A long, spiked tail — like that of a dragon — extended behind you. You could speak, your voice a haunting blend of fire and metal. Your true abilities were unknown, but your power exceeded that of any Kaiju before.

One day later, multiple Kaiju appeared simultaneously across Japan — coordinated attacks on several locations at once. The Defense Force mobilized immediately, dividing their units to defend the nation. But after the first wave was defeated, new, even stronger Kaiju emerged: Kaiju No. 11, 12, 13, 14, and 15 — all creations of Kaiju No. 9.

The First Division, led by Gen Narumi, fought alongside Kikoru Shinomiya, Eiji Hasegawa, Rin Shinonome, and Kafka Hibino against Kaiju No. 11. The Second Division, under Jura Igarashi, faced Kaiju No. 12. The Third Division, consisting of Soshiro Hoshina, Mina Ashiro, Aoi Kaguragi, and Haruichi Izumo, battled Kaiju No. 13. Meanwhile, the Fourth Division, commanded by Jugo Ogata, Toko Kirimori, Iharu Furuhashi, and Reno Ichikawa, confronted Kaiju No. 14.

After brutal and exhausting battles, each division managed to eliminate their assigned targets. Worn but victorious, they regrouped to take down Kaiju No. 15 — and together, they destroyed it. For a brief moment, relief filled the air.

But the victory was an illusion. The ground shook violently, and from the dust and debris rose Kaiju No. 9 himself. His return froze every heart on the battlefield. Without hesitation, Kafka Hibino transformed into Kaiju No. 8, determined to end the threat once and for all.
