I'll admit I made a mistake, the anime translation makes him say something drastically different. However, you know he's trying to be a pro hero right? They have agencies, interns, and sidekicks. Why jump to the conclusion it's perverted? On top of the fact he's always beaten whenever he says something perverted, and no one beats his ass for this. I can comfortably say this was mere advertising for his hero agency in the future, NOT an attempt at hitting on a child.
