About KAMUI
KAMUI drops players into a 2D arcade shooter where a massive man‑made craft, built on Xaffiquel Theory brain‑fusion, threatens humanity. The story spans six meticulously designed stages that alternate between high‑ and low‑altitude combat.
Score is driven by an auto‑targeting Lightning Attack that builds a multiplier, while the Lightning Katana destroys enemy bullets. Players may choose fixed difficulty levels or an adaptive mode, and a new TATE (rotated) display option adds a vertical view.
01 / THE GUIDE
Story and Setting
Centuries after the events of RefleX, civilization rises again only to confront KAMUI, a fighter craft based on ‘Xaffiquel Theory’ brain‑fusion technology. The narrative frames an ancient structure once worshiped as a god as the source of divine retribution.
The craft carries a paradoxical secret that becomes humanity’s only hope for salvation, guiding the player through six stages that echo the lingering legacy of the twisted mind behind the technology.
- Observe the brief story interludes between stages for visual cues that echo the lore.
- Note recurring ancient design motifs; they often foreshadow enemy patterns.

Core Gameplay Mechanics
Gameplay consists of 2D arcade shooting across high and low altitude planes. An auto‑targeting Lightning Attack generates a score multiplier, rewarding continuous hits on enemies.
The Lightning Katana provides a defensive option by destroying incoming enemy bullets, allowing players to clear dense bullet fields while maintaining offensive pressure.
- Practice timing the Katana to remove bullets without breaking your attack rhythm.
- Maintain a steady stream of hits to let the multiplier climb as high as possible.

Difficulty and Rank System
Players can pick from several difficulty settings that adjust enemy placement and algorithms, or enable an adaptive mode that tailors difficulty to the player’s skill level.
The game includes a rank system alongside its difficulty settings, giving players a benchmark to pursue as they seek mastery.
- Start on a lower difficulty to learn enemy patterns before trying adaptive or higher settings.
- Focus on consistent accuracy rather than risky high‑score tricks to improve rank.

Display Options
The English version adds a TATE (rotated) display mode, which presents the game in a vertical orientation without changing core mechanics.
This mode can be useful for players with tall monitors, offering a fresh visual perspective on enemy approaches and stage layout.
- Try TATE mode on a monitor that can rotate to see how enemy entry points shift.
- Compare comfort and reaction timing between standard and TATE layouts.
