Second Division Base

Lore & Background

The facility houses specialized equipment required for modern Anti-Kaiju warfare, including powered suits made from kaiju remains that grant officers increased strength, speed, and durability. These suits have a total power output measured as a percentage ("unleashed combat power"), varying per individual, with a maximum of 100%. Personnel stationed here are often among the most experienced in the force, though new recruits like Kafka Hibino integrate into these ranks to bolster numbers during surges in activity. The base represents the intersection of military order and the chaotic reality of monster attacks.

In Their Own Story

The hum of ventilation systems filled the briefing room as Captain Mina Ashiro stood before the holographic map. Shadows danced across the faces of the assembled soldiers of the Third Division, reflecting the tension of a recent alert. Kafka Hibino adjusted his uniform collar, feeling the weight of the insignia on his chest. Outside the reinforced windows, the Tachikawa base skyline glittered peacefully, unaware that the monsters watching from the dark were waiting for their chance to strike.

The Second Division Base serves as a critical frontline hub within Japan, positioning its personnel at the center of the country's highest-risk zone for Kaiju incursions. Strategically, this location allows for rapid deployment to protect dense population centers and government infrastructure, making it one of the most vital strongholds in the nation. Kaiju appearances near this sector are frequent enough that constant vigilance is mandatory. Defenders operate on a standby rotation system, ensuring that elite teams can launch within minutes of an alarm. The base architecture prioritizes speed, featuring large hangars for armored transport and streamlined briefing rooms designed for quick tactical updates during crises. Daily life here blends rigorous military discipline with the psychological burden of potential death. Recruits undergo intense combat training alongside veterans who have survived multiple encounters. Despite the danger, camaraderie thrives within the mess halls and barracks, fostering a bond that keeps soldiers grounded when facing monsters capable of leveling cities. The facility remains active day and night, a silent guardian against the shadows looming over Japan.
