It's not quite as over the top as Nichijou gets but it's still girls being cute and funny with occasonal
And while Hakase and Kanna are both cute lolis, I'd say they're different kinds of cute. Hakase acts her age and is more rambunctious. Kanna is more mature and is actually kinda stoic in how she presents herself.
They're both cute and deserve protection and head pats though.
