Nah the reason I don't care about him is because much like the other students the dude is worthless, his costume is shit tier and there's nothing to his character aside from being a pervert. Which keep in mind even Japan thought him telling that Eri kid to come to him when she's 18 to be in poor taste and it tanked his popularity there :skully. I don't even care really that he's the obligatory perv character but that's literally all he is. There's never anything to mix it up, no other joke or stand out personality trait so it gets repetitive and boring. I can at least say something else for a character like Jiraiya or even Roshi. The only other thing I can remember from Mineta is that one joke with him breaking the 4th wall and saying that his character design makes it impossible for him to play a guitar. That's about it :kobeha.
