Cards Can't Save Humanity, Reborn Mecha Masters Can

[Cards can't save humans, but mecha masters can! I once died in a well-planned betrayal, making a deal with an inhuman being in the wreckage of a mecha on a rainy night. After rebirth, I became a pawn at the mercy of fate. Facing a future that is contrary to my established destiny, I feel like I have fallen into a carefully crafted web. But, this time, the chess piece refused to move. This time, use everything you have to change everything! [Card + Rebirth + Mecha + Black Humor]
