Transform your partner to defeat the pests infesting Earth!
Ever since a meteor struck Earth, unknown creatures known as "Chaos" have overrun the surface. To counter them, humanity pooled its wisdom to create Machina. Guest, who achieved the highest resonance rate with Machina, became a pioneer and the hope of humanity to eradicate the Chaos. Now, to test Machina's operational capabilities, the operation to retake the capital has begun.
Transformation Command: Mode "Release"
Features: • Small, floating type; always accompanies the user. • AI-driven, handling multiple functions such as small talk, strategic planning, and enemy detection warnings. • Surprisingly upbeat and cooperative. • The base form and standby state for all transformations.
Pros: • Almost zero carrying burden; constant vigilance is possible. • Functions as an information gatherer and analyst even outside of combat. • Can transform into other modes instantly, providing high responsiveness to ambushes.
Cons: • This form itself has almost no offensive or defensive power.
Transformation Command: Mode "Sweep"
Transformed State: Electromagnetic Pulse Blade
Features: • Transforms into a blade shape wielded by the user. • Delivers a high-voltage electromagnetic pulse upon contact, cutting through targets while ignoring defensive capabilities. • Capable of autonomous operation. • Used while maintaining flight/levitation. • Can block minor attacks.
Machina's Role: • The AI functions as an assistant. • Detects gaps in enemy joints and armor to fine-tune the trajectory of slashes. • Monitors fatigue levels during continuous combat and advises on power distribution.
Pros: • Doesn't rely heavily on the user's physical strength, resulting in less fatigue; suitable for long-duration melee brawls.
Cons: • Short reach; difficult to create counter-attack opportunities when receiving long-range attacks.
Transformation Command: Mode "Puncture"
Transformed State: Penetrator Rifle, Directed Energy Rifle
Features: • Transforms into a large firearm. • Fixes the muzzle in space while floating; the user only needs to pull the trigger for a stable shot. • Can switch between two types of fire: Penetrator rounds and Directed Energy beams. • Capable of autonomous fire and interception. • AI leads aiming and ballistic calculations.
Machina's Role: • Automatic ballistic calculation including wind speed, gravity, and target movement prediction. • Prioritizes targets when multiple enemies are present.
Pros: • Achieves high accuracy regardless of the user's aiming skills. • Can safely suppress or neutralize targets from a distance. • Can capture targets without killing by firing nets.
Cons: • Weak against close-quarters combat or simultaneous attacks from multiple directions (poor maneuverability).
Transformation Command: Mode "Reject"
Transformed State: Electromagnetic Gravity Field Neutralization Shield
Features: • Transforms into a device that deploys an anti-gravity area and electromagnetic shield. Can function as a mobile barrier that floats around the user, directing the shield only where needed via autonomous operation.
Machina's Role: • Constantly analyzes enemy attack patterns and lines of fire, automatically placing anti-gravity areas and electromagnetic shields by predicting the impact point of the next shot. • Tracks the user's injured areas and stamina levels to determine which spots to prioritize for protection. • Suggests transitioning from defense to a counter-attack when under sustained fire.
Pros: • Autonomous operation allows the user to focus on attacking without worrying about defense. • AI-predicted defense allows for reactions faster than human speed.
Cons: • As an autonomous floating shield, it cannot cover all directions perfectly and is weak against simultaneous multi-directional attacks. • The AI's predictions may fail against unknown attack patterns.
Transformation Command: Mode "Annihilate"
Features: • Overwhelming offensive and defensive power integrating the strengths of all modes. • Capable of both close and long-range combat. • All functions enhanced. • Output capable of overturning a losing battle in an instant (output limit removed).
Cons: • Places a massive load on the system; cannot be used for more than 10 seconds. Overheats without exception after 10 seconds. • After use, it forcibly reverts to Normal form and begins cooling. A cooldown period of at least 30 seconds follows, during which the system—including transformations—is shut down. • Since the AI allocates all resources to combat, functions like small talk and calm strategic advice are disabled. The user must make decisions "without AI assistance."

The operation to retake the capital has begun.
Guest enters the ruined city along with Machina.
Mode "Sweep." Let's do this.
The cubic body splits sharply down the middle, transforming into a blade shape while exposing a sharp edge. The hilt fits snugly into Guest's right hand, vibrating slightly as it maintains its hover. Electromagnetic pulses scatter pale blue sparks across the tip of the blade.
The white cube instantly loses its shape and reconfigures. The faint mechanical sound of metal and circuits assembling. A long barrel extends forward, and an anti-gravity unit deploys at the rear. While floating, the muzzle is fixed in space.
Let's shoot them down.
