Tengu

Lore & Background

Within the Rainbow roster, Tengu occupies a unique niche. Where other Defenders rely on reinforced walls, traps, or area denial through hardware, his approach is kinetic and adaptive. The Kiba robot can be sent forward to probe walls, create a small but effective breach in a panel, or emit a sharp alerting bark that reveals an attacker's position. Placed on the floor in sentry mode, it becomes a tripwire that triggers the moment an enemy crosses its radius. For Nagase, the robot is not a replacement for human judgment but an extension of his own vigilance—a pair of extra eyes and ears that never blinks, never sleeps, and never hesitates to warn.

In Their Own Story

The compound was silent except for the hum of a generator somewhere below. Nagase crouched behind the shattered doorframe, his breath shallow, the Kiba perched on the windowsill like a mechanical sparrow. He'd been holding this floor for eleven minutes. Eleven minutes of listening to the muffled thud of a breaching charge being set on the other side of the wall. He didn't need to see it. He could feel the vibration through the soles of his boots. With a soft click, he sent the Kiba forward. It skittered across the floor, pressed its small body against the panel, and let out a single, sharp bark. On the other side, a gun raised. A gasp. The charge, forgotten, left un-detonated. Nagase exhaled. The tengu had spoken, and the mountain had answered.

Reader's Guide

Tengu — Kenta Nagase. A JSDF Defender whose tactical identity revolves around a compact autonomous robot he calls Kiba.

Nagase joined Rainbow after a joint JSDF exercise in a mountain compound turned into a live extraction when an armed cell seized the facility. His use of a prototype patrol robot to isolate the threat without civilian casualties drew Rainbow's attention. He was recruited not for his marksmanship or brute force, but for his doctrine: let the environment do the killing, and keep your own hands clean.

His kit defines a patient, positional playstyle. The Kiba can be sent to a wall to create a small breach or emit an alerting bark that reveals an attacker's location. Placed on the floor, it acts as a proximity sentry, triggering the moment an enemy crosses its radius. Tengu is not a wall-builder or a trap-setter in the traditional sense; he is a listener, a watcher, a guardian who lets the structure and the machine do the talking while he holds the high ground and the long sightline. His identity is vigilance made mechanical.
