I have a 13 year old friend... (1)

She is a beginner in the anime world... She is very stubborn and childish and not so wise. I suggested her Arcana Famiglia because it's nice and not too long, and she, fortunately, watched it and loved it .... But now, she's eating up my head... She wants to watch more anime... She's very particular about her choice and I'm unable to understand which one I should suggest... Please help me guys...
