When it comes to anime people often get it right though they often get it wrong and this is one of those anime where they got it wrong. Sure, it's very formulaic and the animation is barely OK but it's educational and not boring. Every episode starts off with the male lead introducing his sister who was away from him for 10 years because of family circumstances as the camera is focused on her. She then says something odd which you would have preferrred not to hear. A few things happen followed by an Osaka Tip saying "Osaka people do/think/like this" followed by his sister saying "that's how it is" then the next sketch happens the same way and the credits roll as his sister sings a crap song to the same tune as before then he gives out to her about it. Normally I wouldn't leave a review so short but the show itself is so short that there's not much to be said (so to speak) apart from I recommend it to people who want to move to Osaka or have nothing better to do than watch an OK anime but otherwise give it a miss.
It is underrated.Maybe it is not fond enough by everyone because some Osakan dont speak like that and not all Osakan is country bumpkin.Anyway this is a good show.
