We agreed on mecha combat, so what the hell is this about your physical body exploding into a planet

In a world where mecha combat has become the norm, a transmigrated individual finds himself in a predicament - his mecha is stolen before its assessment. However, he awakens a unique ability known as "Knight Doesn't Die Barehanded," which allows him to increase his stats one hundredfold when his mecha is destroyed. The longer the time limit before the mecha's destruction, the more permanent the stat boost to his physical body will be. This leads to the emergence of a mecha pilot who prioritizes attack over defense, shattering conventional wisdom. As he survives by destroying his mecha, he gains the strength of a Demon King, unleashing devastating power upon his enemies while defying the expectations of those around him.
