She Married a Tramp, Yet He's the Almighty Overlord

The superhero with great military achievements was framed and mistakenly believed that he had killed innocent people indiscriminately. He was exiled to a small town in the United States as a socially isolated scavenger. The wealthy daughter he had saved gave up her huge trust fund and would rather be expelled by her family than marry down. Faced with the exploitation of the elite class, he finally awakened his superpower and shattered the villain's conspiracy.
