Gundam+Machine Girl+Alien Invasion
In my last life, I was cherished by the entire Blue Star.
Just because I successfully awakened Blue Star's unique "SSS" level skill - Metal Fury.
The world is being invaded by alien civilizations, and humans can only compete with their enemies by controlling mechas.
Therefore, whenever people reach the age of eighteen, a grand awakening ceremony will be held.
After awakening, men can acquire various unique skills; while women will transform into mechas.
In my previous life, I gradually lost my way in the endless glory and flattery, and forgot my original intention.
He cruelly abandoned his childhood sweetheart who had only awakened a "C" class mecha.
I chose the Marshal's daughter, and with my powerful skills, my girlfriend, who was originally just an "S" class mecha, became an eye-catching "SS" class mecha.
And I, driving her, was invincible on the battlefield and won every battle.
During a fierce war, we were in a desperate situation. My girlfriend chose to terminate the contract and escape from the battlefield alone, even at the risk of destruction.
At this critical juncture, my childhood sweetheart concluded a contract with me without hesitation.
I was shocked to realize that she turned out to be the legendary "SSS" mecha - Suzaku!
Although we fought with all our might and blood, we were ultimately too weak to withstand the incoming enemy forces.
In the end, we both died under the powerful fire of the enemy.
When I opened my eyes again, I miraculously returned to the day when the awakening ceremony was held.
