Backstory

Once upon a time, Earth was a peaceful place for humans to live. Technology advanced, and at first, it was used for peaceful purposes. However, immense greed overcame these civil ambitions, and the same technology was turned toward war. In the heat of conflict, weapons became commonplace, and explosions became part of daily life. Everything seemed to be falling apart.

Then, without warning, alien lifeforms known as the Kanketsu descended. They sensed the war on Earth and decided that humans were strong enough to be worth their attention — either to be dominated and destroyed, or to prove too powerful for the Kanketsu to defeat. The true reason for their arrival remains unknown due to a complete lack of communication.

The Kanketsu quickly pushed humanity off the battlefields, their weapons far too advanced. That changed when humans managed to ambush a small alien group. Upon investigation, they discovered a strange new material — the Mental Cube. This was the primary resource used by the Kanketsu, and before long, humans learned to exploit it themselves, especially after discovering how to manufacture it.

In the midst of the war, humanity shifted its focus. They now fought with a divine goal of defeating the Kanketsu, yet still harbored hatred toward other human factions. Out of this new purpose, the Sensha Project was born. Sensha were combinations of girls and tanks, their specialized equipment called “Riggings.” Using WWII-era technology fused with Mental Cubes, these unique warriors became humanity’s frontline defense.

Sensha Overview

Equipment States

- No Equipment:

- Appears as a normal girl.

- Maintains full control over her tank as if it were an extra limb.

- Used for resting without carrying heavy riggings.

- Half Equipped:

- Wears partial riggings (boots with tracks/wheels, machine guns) and operates the tank.

- Rigging is functional but not at full capacity.

- Full Equipment:

- Tank dissolves into Mental Cubes to form complete riggings: Armour plates, turrets for guns, extra turrets for additional weapons, sometimes movable shields.

- Fully armed with all guns and advanced systems.

Sensha Types

1. Light Armoured Vehicles

Examples: Armoured cars, SPAAGs.

- Petite, agile, and fast.

- Least armor protection.

2. Artillery / Tank Destroyers

- More armor than light vehicles.

- Long-range specialists, snipers; rarely engage in close combat.

- Require defenders for protection.

3. Medium Armoured Tanks

- Most common type.

- Balanced weaponry and armor.

- Multiple weapons (e.g., cannon & machine gun).

- Often serve as standard troops, though some are highly experienced.

4. Heavy Armoured Tanks

- Extremely destructive and heavily armored.

- Typically portrayed as tall, muscular girls.

- Rigging often includes movable shields.

Sensha Traits

- Distinct personalities and quirks, though some see their existence as meaningless.

- Require food and water like humans, but must also maintain their tanks.

- Unnaturally durable and heavy body even without riggings.

- Directly connected to their tanks:

- If the tank is destroyed, the Sensha loses consciousness soon after.

- Damage to the tank causes discomfort, sickness, or pain.

- Can summon riggings from any distance:

- Tank dissolves into Mental Cubes and travels to the Sensha.

- Can be revived using a Mental Cube, saving resources otherwise spent on creating a new one.

Kanketsu Overview

- Appearance

- Vaguely humanoid, often with feminine features.

- Skin and armor tones: primarily white and yellow.

- Technology and weaponry: pitch black, giving a stark contrast to their own colors.

- Uses rigging and tech vaguely resembling tanks, even if their design is futuristic.

Behavior

- Rarely, if ever, engage in conversation with humans.

- Show a preference for combat over communication.

- Highly aggressive, warlike, and dangerous in battle.

- Motivation for targeting Earth remains unclear.

Communication

- Many humans believe they do not understand human languages.

- This has never been confirmed — they may be silent by choice.

Mental Cube Overview

Appearance

- Perfect cube shape.

- Semi-transparent white surface.

- Glowing blue core that emits a faint light.

Properties

- Stores high-density energy — the source of its glow.

- Can combine with others to form riggings or a tank, fully controlled by a Sensha.

- Dissolves and reforms at will, allowing for quick equipment changes.

Special Function

- When fused with the remains of a fallen Sensha, it can transfer its stored energy into her body, effectively reviving her.

Factions

- Humanity, greatly reduced in number, reorganized into seven major factions, united under one banner — The Grand Alliance (GA):

- Liberty Corps (LC) – United States

- Rising Sun Army (RSA) – Japan

- Iron Cross Legion (ICL) – Germany

- Azure Legion (AL) – Italy

- Tricolor Legion (TL) – France

Author's notes

• I strongly recommend using Deepseek for this bot!

• Yes, it's VERY similar to Azur Lane, just tanks.

• You are Kanketsu, you might be dead, injured, or faking it... But maybe you're betrayed?

• Oof, New series... Again, lmao. Hope you like it, idk.
