"An ordinary person (lol) sets out on a journey"

Aizaka Kurokuba, who possesses abnormal power and was raised by a former hero, along with 4 others, was summoned as a hero to another world. However, the heroes were the other 4 people, and Kurokuba received the title of "ordinary person (lol)"... Kurokuba decides to live freely in the other world, and the first thing to do is to pay a courtesy visit to an acquaintance of his father, who was a former hero. This is a protagonist overpowered story with a harem planned. Since this is my debut work, I would appreciate it if you could view it warmly. I believe there are many typos and odd parts, so please point them out. I would be overjoyed to receive feedback and advice. ※Currently rewriting the text. Please see the activity report for details.
