Alright so I haven't seen this anime in a long long time, but what really stood out to me were 2 things- 1. The art style. I absolutely loved how the story was in another world, with a different style, but also had real life elements in it. Using the name Lewis Carole felt more like a fictional character than the actual author- but also, was it the real Lewis Carole? You didn't know what was going to happen (though if I were to rewatch it they might have been screaming it in your faces what the twists were going to be). The characters aresuper mediocre and the relationship between the brother and sister were....
... why does anime do that? Oh well. It really added to the "what the heck is gonna happen?" factor. Other than that a lot of the characters actual personalities were pretty generic- but you still wanted to know where things were gonna go. I recommend watching this anime, because it still has some creative aspects to it worth watching!
