This is an era where mechas are king and fight against titans.
Chen Mo, a high school graduate with D's in strength, speed, and fitness, is a complete "mecha waste".
Relatives introduced him to drive an engineering mecha, but he unexpectedly dug out a black mecha with a very different style.
It didn't speak, it just asked in his mind: "Link? Boy."
Chen Mo: "... My ratings are all D."
Mecha: "What a coincidence, my rating is EX, specializing in treating dissatisfied people."
When the beast tide came, the black mecha slowly stood up, and Chen Mo realized that he might not be driving a mecha, but a mythical mecha!
