[Anime Crossover] The C-Class Hero Saitama's Calamity

My name is Saitama, and I'm a Class C hero. I became a hero because I felt like it. Today, too, I'm working hard at my hobby. By the way, the biggest disasters in my life are mosquitoes, cats, and Saiki Kusuo. "Disasters" 1. Pairing: Saitama-sensei x Saiki. 2. A ridiculous story born from a wild imagination. 3. To make the age gap reasonable, Saiki is a second-year university student in this story. 4. Irregular updates. 5. He's bald, but he's a very handsome bald guy, so mwah to Saiki.
