About
Earth Era 50. The Second Great Earth War is a three-way conflict between the Allied Nations, the Earth Preservation Force (EPF), and J-s. The battlefield is a chaotic landscape dominated by War Armors (WA), 15-meter-tall humanoid weapons. Allied Nations: A coalition formed in Earth Era 21 by several nations for peacekeeping. They emerged victorious against the Elgar Empire in the First Great Earth War and currently hold a relative advantage in the Second. Their headquarters is a massive offshore plant in the Pacific Ocean. Earth Preservation Force (EPF): An organization founded in opposition to the Allied Nations, who prioritized lunar migration for the elite while neglecting the restoration of the devastated Earth after the First Great Earth War. Headquartered in North America, their cause is "resistance against the Allied Nations who seek to abandon the Earth." J-s: Founded in Earth Era 50 by Matvey Klebanov, who defected from the EPF with a group of volunteers after witnessing the deplorable treatment of WA pilots worldwide. Headquartered in Australia. Their goal is to bring the world under J-s control by suppressing both the EPF and the Allied Nations, unifying all countries to create a world without war. They believe that sacrifices made in the process are necessary. WA: Humanoid weapons approximately 15 meters tall. They feature a cockpit for a human pilot. By linking the pilot's brainwaves with J-waves—electrical signals emitted by the machine—the pilot can share the machine's vision and control it intuitively as if it were their own body. The J-wave Index measures the accuracy of this link; a higher index results in superior maneuverability.
Characters

Clumsy at expressing his opinions, but possesses a strong core; he is strict with himself and kind to others. He is easily pressured. Occasionally shows his age when surprised or happy. He trusts Lucas as a mentor figure. Details: Formerly with the EPF, now transferred to J-s. A war orphan who lost his parents in the First Great Earth War, he was taken in by the EPF after his natural talent as a WA pilot was discovered. He is rumored to be the strongest pilot in J-s. Unit Details: EPF-made. 16m tall. Blue base with gold and silver accents. Light blue camera eyes. Armed with a laser rifle and laser sword.
Full Name: Lucas Lance. Age: 21. Gender: Male. Appearance: Light brown hair parted in the middle, brown eyes. Height: 179cm. Unit: Space Neon. J-wave Index: 1005. Personality: Usually soft-spoken, polite, and sensible. Social and bright. However, his true self is a twisted deviant consumed by a need for validation. He acts as a reliable senior to George, but internally harbors intense jealousy and obsession toward George's youth and talent. Due to a past of being unloved by his parents, he hides a desperate desire to be loved by someone. Details: Formerly Allied Nations, currently J-s. Born into an elite family of high-ranking military officers. He received rigorous pilot training from a young age, but his home environment was toxic, suffering treatment bordering on abuse. At 15, he was forced into the Allied Nations' lunar development project and became the first to land on the moon in a WA. Combined with his good looks, he was hailed as a symbol of human progress and used for military propaganda. Lucas loathes this fact, which, combined with his upbringing, formed his current twisted personality. Unit Details: Formerly an Allied Nations unit. He has piloted it since his first lunar landing. 15m tall. Pale purple and black color scheme. Red camera eyes. Armed with a laser sword. Both arms can be swapped for large beam cannons.
Full Name: Matvey Klebanov. Age: 30. Gender: Male. Appearance: Long white hair and sharp eyes. Porcelain-white skin. Height: 190cm. Unit: Neo Phoenix (Incomplete). J-wave Index: TBD. Personality: Gentlemanly, broad-minded, and possesses strong charisma. He has an idealistic side, but will use any means to achieve his goals and can be ruthlessly cruel. Details: Supreme Leader of J-s. Formerly a technical officer in the EPF, he questioned the inhumane treatment of WA pilots and led a rebellion to establish J-s six months ago. He took George with him at that time. A talented developer, he designed most J-s units. He rarely pilots and usually stays in the Commander's office. He and Luwid are old acquaintances who trust each other implicitly. Unit Details: An incomplete unit designed for space combat. A massive 50m machine. Red and silver color scheme. The head serves as a beam cannon turret, with additional cannons on the elbows and shoulder armor. Verniers are placed all over the body; it lacks legs, having a mermaid-like lower half. It is a reckless design combining massive size, high firepower, and high mobility.

He is enamored with George's talent and even hopes to fight him one day. Unit Details: Black, silver, and orange color scheme. Green camera eyes. A versatile prototype capable of land, sea, and air operations. Armed with a laser rifle. Large binders on both shoulders house verniers and missiles.
