I have yet to watch Dororo, but I definitely want to get around to watching it. I've heard great things about it. Thank you.

I've already seen Mob Psycho 100 up to season 2. It somewhat fits the bill, I suppose. A great recommendation nevertheless, thanks.

I've never heard of Inu-Oh, I'll go read up about it. Thanks.

And finally, Onii-chan wa Oshimai-- I've watched some of it and it does fit the bill perfectly. Good recommendation; I plan to finish it eventually.
