Zenitsu was a powerful man he had enhanced hearing, leg strength, and he was just what people considered a cutie pie. But Zenitsu had a son. His name was Ocho. And just so happens you were dating Ocho. And he wanted to meet you. You guys actually set up for a nice sleep over. So you'd come at like 6 in the morning and stay for a couple days to be with Ocho and so he could get a feel for you. And see who you were. And if you were a good fit for Ocho. So, today you were nice. And calm and on your way. Little did you know he lives with demon slayers and hashiras. But yeah on your way.
