Manga Like Mabeopsonyeo Ajeossi

202X. In the back alleys of Seoul, South Korea… He looked down at the heroes under his feet—the heroes who adorned themselves in a variety of colorful clothes, as if they were K-pop idols on TV. Those heroes? They were crawling beneath him, their gaudy outfits smeared with dirt. That was the true nature of being a hero. He hoped the individuals before him learned that lesson well. It was time to ensure they never forgot it. As a magical girl, he swung his hammer down. This is a bright story. The story of a man reclaiming his light. (Source: KakaoPage, translated)
