Mecha: Dawn Cavalry

"When civilization is on the verge of collapse, the last hope of mankind is to drive a body of steel and charge into the darkness." World view setting: In the year 2187 of the New Era, the earth no longer belongs to a single human civilization. After the "Stargate Incident", humans mastered space jump technology, colonized hundreds of galaxies, and established the "Earth Federation." However, the alien civilization "Shadow Clan" suddenly invaded and made a living by devouring the planet's ecology. Wherever it went, not a blade of grass grew. Humanity was retreating steadily until it developed the ultimate weapon - the "Dawn Series Mecha." But the Dawn Mecha is no ordinary weapon - it requires a "chosen pilot" with a "neural synchronization rate" of over 90% to activate it, and there is only one person in the world who has successfully piloted it... And eventually disappeared. Now, the Shadow Clan has made a comeback. A forgotten boy picked up the broken cockpit from the wasteland and restarted the sleeping "Dawn Iron Cavalry".
