My Spider Familia

PS: The woman on the cover is not the female lead! She is not the female lead! She is not the female lead! The author picked a random image from the internet at the last minute.

My name is William Finney. This is the story of how I became a hero. One time, while accompanying my father on an herb-gathering trip, I met a gigantic spider that seemed to be having a bit of trouble. It ate so much that its web couldn’t support its own weight. Feeling sorry for it, I fed it some fries. It seemed to love them, and it followed me around ever since. I thought it was clever, so I took it in as a pet. We became friends, and it wanted to help me become a hero and fulfill my wish. That was how the adventures surrounding us gradually began.
