The focus of this series, that some other people have obviously missed, is not disability. At it's core it's a slice of life series about a girl with ESP powers that goes around encountering short stories evolving the supernatural. Each chapter is like a fairy tale, an urban legend, a fable, et. It's almost like Mushishi.
Not every story involving a disabled person is about the disabilities. And if your dismiss a series just because it overlooks the disability after reading merely 2 chapters you should not be writing reviews.
Anyways, if you read Franken Fran by the same author, this series is pretty similar except it take a more lighthearted approach and there isn't nearly as much ironic deaths/tragic ends. Imagine Mushishi + Franken Fran with a kind girl as the MC. It's a nice quick read and definitely accomplished what it set out to do.
